Let’s start talking pitchers. It’s time to move on to the wackiness that is starting pitcher metrics. So who is part of the weird and the wonderful as April’s books have closed? Let’s find out.

Using baseball-savant data and some Python code, I have written a script that will loop through a pitcher’s three most recent appearances and flag any pitcher who has shown an increase in their fastball velocity. In raw form, it looks something like this:

Looking at the table above we can see that each of these three pitchers increased their fastball (“FF” in savant data) consistently over their last three appearances. Don’t believe me? You can check my work with Savant visualizations:

While I wrote more specifically about the merits of paying close attention to game-by-game fastball increases, quoting many other studies and great pieces along the way, I won’t be writing about it again here. Instead, I’ll simply show you a list of the starters and relievers who have increased game-by-game average velocity on their four-seamers and hope that you can take it from there. Sure, you could scroll through stacks of player pages to find players who have increased velocity until the cows come home, or you could write some code that will detect those increases and flag those players for you. I chose the second way. If you find it useful, I’ll do it on a more regular basis. That’s it. This post is more about the data than the words:

Welcome back to the SP Drip. My goal for this bi-weekly column is to comb through the upcoming schedule each week to find a few under-owned pitchers (less than 50% ownership across Ottoneu) who could be used to help you hit your games started cap in head-to-head leagues or to make sure you’re hitting your innings pitched cap in points leagues. Tuesday’s article will cover the weekend (Friday, Saturday, Sunday) and Friday’s article will cover the upcoming week (Monday, Tuesday, Wednesday, Thursday). That way, you’ll have time to start your auctions in time to actually drip these pitchers into your lineup.

Upcoming Schedule:

Teams with favorable schedules next week include the A’s, Braves, Mariners, Mets, Orioles, Padres, Reds, and Tigers.

Teams with tougher schedules include the Astros, Blue Jays, Diamondbacks, Dodgers, Nationals, Phillies, Red Sox, Rockies, and White Sox.

Highlighted matchups:

The Orioles visit the expansive ballpark in Kansas City and get to face the punchless Royals offense next week. There are two starters who I’m recommending: Tyler Wells and Kyle Gibson (again). The former has pitched particularly well this year and pitched a seven inning shutout against the Tigers a week ago. In his last start against the Red Sox, he struck out seven — a season-high — and allowed just two runs on four hits in 5.2 innings. Gibson has been a common recommendation in this column and he has continued to provide serviceable production when the matchup is right.

Outside of a seven run blowup in his first start of the season, Drew Smyly has pitched phenomenally this year. He took a perfect game into the eighth inning against the Dodgers a week ago and then held the Padres to two runs on four hits in five innings his last time out. A matchup with the Nationals should be a piece of cake after suppressing those two offenses.

The last two recommendations are pretty risky considering the number of home runs each of them has allowed. Still, both Domingo Germán and JP Sears sit within the top-20 in the majors in strikeout-minus-walk rate. Despite their issues with the long ball, they’re striking batters out and aren’t allowing too many free passes; that’s certainly a sign of better things to come for both of them. Of the two, I’d be more inclined to start Sears since his home ballpark is a haven for fly ball pitchers like him.

Recap: April 24–27

Woof. That start from José Suarez against the A’s was absolutely brutal. It completely wiped away any positive vibes from Gibson’s gem or Canning’s solid start. Brad Keller continues to struggle with his command, which means he’s bleeding points despite allowing just a single home run this year.

We’re a month into the season and the average points per inning pitched for the recommendations in this column sits at 3.24. That’s not great, but it’s not a disaster either. The 50% ownership threshold really puts a strain on the kinds of pitchers I’m able to include since Ottoneu has such deep rosters. Have these targets been helpful for you, dear reader, or do I need to be a little more discerning with my recommendations week in and week out?

Welcome back to the SP Drip. My goal for this bi-weekly column is to comb through the upcoming schedule each week to find a few under-owned pitchers (less than 50% ownership across Ottoneu) who could be used to help you hit your games started cap in head-to-head leagues or to make sure you’re hitting your innings pitched cap in points leagues. Tuesday’s article will cover the weekend (Friday, Saturday, Sunday) and Friday’s article will cover the upcoming week (Monday, Tuesday, Wednesday, Thursday). That way, you’ll have time to start your auctions in time to actually drip these pitchers into your lineup.

Upcoming Schedule:

I’ve started pulling current season data for team offenses to assess matchups rather than continue utilizing the rest-of-season projections. That means there are a bunch of teams who were projected to be good who are currently underperforming and vice versa.

It’s a pretty rough slate of matchups this weekend. It doesn’t help that the Giants and Padres are playing in Mexico City which is at a higher altitude than Denver. The ball should be flying in that short two-game series.

Teams with easier schedules include the A’s, Cubs, Orioles, Twins, Red Sox, Reds, and Royals.

Teams with tougher schedules include the aforementioned Giants and Padres and also the Angels, Astros, Brewers, Cardinals, Diamondbacks, Dodgers, Guardians, Mariners, Mets, Nationals, Rockies, White Sox. and Yankees.

Highlighted matchups:

Despite all those poor matchups, there are a handful of starter’s I’m comfortable recommending. All three of the A’s starters scheduled to take the mound during their home series against the Reds fall below our 50% owned threshold. I’m recommending Kyle Muller again, but if you want to roll the dice with Ken Waldichuk or possibly even Drew Rucinski 루친스키, you could drip them into your lineups.

Nick Pivetta bounced back after a rough start against the Angels a few weeks ago. Last weekend, he held the Brewers to three runs in 5.2 innings, striking out seven and walking just one. He draws the Guardians at home this weekend and that should be a pretty easy matchup for him since Cleveland’s offense hasn’t really started clicking yet.

Dean Kremer followed up his gem of a start against the Nationals with a decent start against the Red Sox yesterday. He allowed four runs in 5.2 innings, striking out five. He did allow a pair of home runs which has been a huge issue for him. The Tigers simply aren’t hitting for power right now and the Orioles will be playing in cavernous Comerica Park. This is a matchup that should go the way his one against the Nationals did.

After two rough starts to open the season, Vince Velasquez has actually been pitching pretty well for the red-hot Pirates. He shut out the Cardinals and Reds and escaped Coors Field with just three runs allowed. Across his last three starts, he’s earned 6.7 points per inning pitched. He’s scheduled to start against the Nationals on Saturday.

The final recommendation is a little up in the air. The Cubs will need to call up a starter to take Jameson Taillon’s spot in the rotation this weekend but it’s a little unclear who it’ll be. Caleb Kilian or Adrian Sampson 샘슨 make the most sense with the former being listed on the Roster Resource Probables Grid. Whoever it ends up being, they’ll have a nice matchup against the Marlins in Miami.

Recap: April 21–23

Two clear wins from the two Orioles starters make this a pretty good week. Hunter Gaddis ended up relegated to long relief and then to the minors and Bailey Falter’s start was pushed back to today.

Yesterday, I identified and discussed the starting pitchers with at least 20 IP this season and last who have raised their SwStk% marks most. Today, let’s now look at the decliners, the pitchers who have suffered the largest SwSk% declines. We’re still in small sample size territory, but such significant declines are still worrisome, especially if paired with a velocity drop.

It’s still quite early to evaluate outcomes like strikeout and walk rates, so let’s stick with underlying drivers of those metrics, like SwStk%. Typically, the higher a pitcher’s SwStk%, the better the pitcher and the lower the ERA, though obviously that’s not going to be the case 100% of the time since we’re ignoring walk rate. But SwStk% gains are almost always a good thing, as that should result in a higher strikeout rate, which means fewer balls in play and therefore fewer hits allowed. So let’s dig into the starting pitchers (with at least 20 innings pitched both this season and last season) that have raised their SwStk% most.

On Tuesday night the first round of the “Beltway Series” kicked off in D.C. and O’s fans showed out. It was a fun night all around. “Fired Up Guy” battled beltway traffic and came down to D.C. to give his support:

Heck, Yennier Cano even road the bullpen cart:

But the real fun was watching Dean Kremer work. Let me take you into a tense moment. It begins with no outs in the bottom of the third inning. CJ Abrams knocked a leadoff single into center field and waited patiently on first base. Next, Victor Robles reached, not first, but second on what was ruled an error by Gunnar Henderson. Take a look:

Upcoming Schedule:

I’ve started pulling current season data for team offenses to assess matchups rather than continue utilizing the rest-of-season projections. That means there are a bunch of teams who were projected to be good who are currently underperforming and vice versa.

Teams with easier schedules include the Braves, Brewers, Cardinals, Diamondbacks, Guardians, Mets, Royals, and Yankees.

Teams with tougher schedules include the A’s, Mariners, Marlins, Rangers, Reds, Tigers, and White Sox.

Highlighted matchups:

Brad Keller sits just below our 50% ownership cutoff and he’s been a common recommendation in these columns this year. He’s continued to struggle with his command early this season but he’s also only given up a single home run and just 14 hits in 21 innings. He gets a nice matchup against the Diamondbacks in their dinger suppressing ballpark next week.

Another common recommendation, Kyle Gibson lines up to face the Tigers two starts in a row, once this weekend and again on Thursday. His last start against the White Sox didn’t go super well — four runs on seven hits and two walks with just a single strikeout in 5.1 innings — but the other three starts he’s made this season have been solid. His two-step against Detroit is just too good to pass up.

Colin Rea is also lined up to face the Tigers next week. He’s been a serviceable starter for the Brewers after Brandon Woodruff went down with his shoulder injury. He had a pretty good season in Japan last year and has looked decent in his return to the States. He held the Padres to a single run across 5.2 innings in his first start but was knocked around by the Mariners in his second.

José Suarez and Griffin Canning are scheduled to face the A’s at home next week. That’s a pretty juicy matchup, but beware the high home run park factor of Angel Stadium. Suarez hasn’t been good this year, with a walk rate that matches his strikeout rate. A date against Oakland seems like a good candidate for a get-right start. Canning is a bit more interesting. Injuries derailed a very promising start to his career over the last few years. He’s healthy and has made a couple of solid starts so far this year.

Jhony Brito bounced back from his ugly start against the Twins by holding the Angels to just a single run across 4.1 innings on Wednesday. He’s scheduled to face Minnesota again next week and will be looking to improve on his seven-run disaster the last time he faced them.

Recap: April 17–20

A really good week with four clear wins and no obvious losses. Keller’s start against the Rangers was dragged down by the five walks he allowed and Michael Wacha just hasn’t been able to replicate the magic he showed in his second start of the season against the Braves.

Welcome back to the SP Drip. My goal for this bi-weekly column is to comb through the upcoming schedule each week to find a few under-owned pitchers (less than 50% ownership across Ottoneu) who could be used to help you hit your games started cap in head-to-head leagues or to make sure you’re hitting your innings pitched cap in points leagues. Tuesday’s article will cover the weekend (Friday, Saturday, Sunday) and Friday’s article will cover the upcoming week (Monday, Tuesday, Wednesday, Thursday).

Upcoming Schedule:

I’ve started pulling current season data for team offenses to assess matchups rather than continue utilizing the rest-of-season projections. That means there are a bunch of teams who were projected to be good who are currently underperforming and vice versa.

Teams with an easier weekend schedule include the Marlins, Nationals, Orioles, Padres, Phillies Rangers, Reds, and Twins. The Diamondbacks and Giants are both playing at home in their cavernous ballparks but they’re facing the Padres and Mets, respectively. On paper, it’s a decent matchup for Arizona and San Francisco because their opponents are underperforming a bit, but be weary.

Teams with tougher schedules include the Astros, Blue Jays, Brewers, Cubs, Mariners, Red Sox, Rockies, Royals, Tigers, White Sox, and Yankees.

Highlighted matchups:

I’ve only got a handful of recommendations this weekend. The Orioles are hosting the Tigers who currently have the worst offense in baseball by a wide margin. That means it’s a great opportunity to drip Tyler Wells and Kyle Gibson into your rosters. The former has had a decent start to the year, allowing just a single walk in three starts with an acceptable amount of strikeouts and hits allowed. Gibson has been a successful recommendation twice already this season and this matchup is his best yet.

The Guardians will host the hapless Marlins offense this weekend, giving you another opportunity to drip Zach Plesac and Hunter Gaddis into your rosters. Plesac has been fine after his implosion in his first start of the year against the A’s. The strikeouts aren’t there but he isn’t walking anyone either. Gaddis has only allowed a single home run this season, relying on weak contact in the air to get many of his outs. His xFIP is an unsightly 5.74, however, so start him at your own risk.

The Rockies will travel to Philadelphia this weekend and Bailey Falter might be lined up for a start on Saturday or Sunday. The Phillies have a double-header today and don’t have an off day this week so their rotation might need to be reconfigured over the weekend. Keep an eye on whether or not Falter is listed as a probable for that series against Colorado.

Recap: April 14–16

A couple of recommendations ended up missing starts last weekend — Dylan Dodd was sent back to Triple-A when Kyle Wright was activated from the IL and Matthew Boyd had his start delayed by rain two days in a row. I think we can call Anthony DeSclafani and Michael Grove’s starts wins with Jhony Brito and Nick Martinez’s clear losses. Seth Lugo also struggled through his start, but ended up earning enough points to call it a wash.

It’s been about a week since I last reviewed the starting pitcher fastball velocity gainers, so let’s take another look. Velocity does fluctuate from start to start, so even though it’s far more meaningful in one game than a pitcher’s walk rate in that game, it’s still subject to the same small sample size caveats as any other metric. So with a bunch more innings in the books, let’s revisit the fastball velocity gainers. It’s also important to check the game logs and see if the velocity has been consistent, or if the average was inflated by just one outing. Finally, it’s helpful to check the maxVel, because a pitcher might not actually be throwing harder, but instead the smaller sample has reduced his lower velocity fastballs that over a season would bring down his average.
