That we’re not selecting the best players. We’re constructing the lineups which carry the most leverage without sacrificing many projected fantasy points.
Both sites are very different on this slate because of pricing, but the overall slate is such that there are no truly great aces. Without ownership data, we’ll focus more on matchups to narrow our pool:
| FD | DK | SIERA | K/9 | BB/9 | HR/9 | Barrel% | Opp | Opp wRC+* | Opp K% | |
|---|---|---|---|---|---|---|---|---|---|---|
| Freddy Peralta | $10,200 | $9,300 | 3.32 | 12.60 | 3.76 | 0.72 | 5.9% | STL | 91 | 22.2% |
| Nathan Eovaldi | $9,100 | $9,800 | 3.61 | 9.33 | 1.49 | 0.91 | 6.9% | CLE | 91 | 23.8% |
| Shohei Ohtani | $10,800 | $8,700 | 3.89 | 10.97 | 3.97 | 0.93 | 7.0% | TEX | 80 | 23.2% |
| Adam Wainwright | $9,600 | $10,000 | 4.06 | 7.99 | 2.10 | 0.99 | 6.5% | MIL | 93 | 24.6% |
| Kyle Gibson | $9,400 | $8,100 | 4.64 | 7.21 | 3.44 | 0.95 | 5.1% | MIA | 82 | 25.4% |
| Glenn Otto ** | $6,700 | $5,000 | 1.76 | 12.60 | 0.00 | 0.00 | 20.0% | LAA | 103 | 23.6% |
TIER ONE: KINDA’ ACES — Peralta and Ohtani
Freddy Peralta is the best pitcher on the slate, but he’s projected at only 75 pitches coming off of the IL. This doesn’t take him out of play if there’s an ownership gap between him and Ohtani that supplies us leverage. If Peralta is rolling — translation: throwing strikes — then, 75 pitches can get us some game depth to compile Ks with his elite K/9. His ceiling is capped at under 30 points, but his median projection might be good enough if we can get 15-to-20 from our SP2, as well.
Recently, I started working through predicting which pitchers limit hard contact and by how much. Today, I dive into if contact out of the strike zone can be predictable and if that contact is weaker than contact in the strike zone. First, I need to go over a couple of concepts
The division of credit for WAR goes with 50% to hitting and 43% to pitching and 7% to fielding. People way smarter than I have determined that split.
Major Note: For simplicity, I’m going to adjust the pitching percentage up to 100% so the fielders are allocated 14% of the credit for what happens when a pitcher is on the mound.
On top of the fielding allocation, not every batter puts the ball in play with the league at an 8.7% BB% and 23.4% K% this season. So now, 68% of all at-bats end with a ball in play with 14% points of that 68% goes to the fielders and 54% (68%-14%) to the pitcher’s batted ball talent. So it works out that 79% (54%/68%) of a pitcher’s batted ball results should be attributed to him. Read the rest of this entry »

Our pitching in MLB DFS isn’t just a source of fantasy points. The price tags on pitchers make it so they shape they dictate the freedoms and restrictions of building our lineups. Before reading this article, it’s highly suggested that you read my article, “DFS Pitching Primer,” so the concepts discussed here make more sense.
That we’re not selecting the best players. We’re constructing the lineups which carry the most leverage without sacrificing many projected fantasy points.
We’ll look at the three aces, the primary pivot off of the aces, and some DK SP2 options. Here’s my preliminary pool:
| FD | DK | SIERA | K/9 | BB/9 | HR/9 | Barrel% | Opp | Opp wRC+* | Opp K%* | |
|---|---|---|---|---|---|---|---|---|---|---|
| C. Sale | $10,700 | $10,200 | 2.43 | 11.70 | 0.90 | 1.80 | 3.8% | MIN | 87 | 24.3% |
| M. Scherzer | $10,500 | $10,400 | 3.17 | 12.17 | 2.48 | 1.35 | 9.6% | SDP | 109 | 20.5% |
| Y. Darvish | $9,900 | $9,900 | 3.26 | 10.90 | 1.91 | 1.13 | 7.1% | LAD | 116 | 21.2% |
| E. Hernandez | $7,600 | $7,600 | 3.33 | 11.09 | 1.67 | 2.09 | 8.8% | WSN | 89 | 23.6% |
| Z. Gallen | $7,900 | $7,200 | 3.95 | 10.52 | 3.54 | 1.30 | 7.6% | PHI | 96 | 22.6% |
| Y. Kikuchi | $7,700 | $7,300 | 4.06 | 9.49 | 3.51 | 1.46 | 9.5% | KCR | 99 | 20.4% |
The blue bar represents the START of a new tier.
I generally don’t include IL’d guys. It’s especially precarious this late when guys could just be shutdown if they are on bad teams.
I view these as 2-3 week rankings given the volatility of pitching so I will include at least 1 and probably 2 more updates on the site before season’s end, but I am updating them regularly on our Patreon.
FYI: instead of updating the rankings in September, I started the Daily SP Chart.
Sometimes conclusions to tough questions just don’t sit right, especially when the answer is “We don’t really know.”. How pitchers control batted balls has never had a simple definitive answer. I’m going to give it another shot.
I have some ideas of what might be a cause, but I want to start with a blank slate. What’s got me diving back in is the following table from a recent article of mine.

While a few percentage points of difference may not seem like much, I expected a lot more regression to the mean with my limited sample size. With just the above information, I felt I needed to re-investigate the subject. I know that some of the regression amounts have previously existed, but I wanted to dive in with some fresh eyes and new batted ball data. Read the rest of this entry »
Cleveland has become something of a starting pitcher factory. It really started with the emergence of Corey Kluber and reclamation of Carlos Carrasco in 2014 and has continued through this year despite a bevy of injuries. Their best starters – Shane Bieber and Aaron Civale – have spent months on the IL and derailed Cleveland’s season, but there has been plenty of opportunity for the likes of Triston McKenzie, Cal Quantrill, and Eli Morgan, showing that Cleveland is likely to remain a pitching force for years to come. I want to focus on McKenzie today.

That we’re not selecting the best players. We’re constructing the lineups which carry the most leverage without sacrificing many projected fantasy points.
We’ll look at the current pool I’m using — the chalk and pivots — and then, cover some questionable plays I’m avoiding for the most part at this time. Right now, this is what I’m looking at:
| FD | DK | SIERA | K/9 | BB/9 | HR/9 | Barrel% | Opp | Opp wRC+* | Opp K%* | |
|---|---|---|---|---|---|---|---|---|---|---|
| Burnes | $11,500 | $10,600 | 2.76 | 12.68 | 2.27 | 0.34 | 4.0% | CIN | 108 | 23.7% |
| Morton | $9,600 | $9,000 | 3.66 | 10.42 | 2.88 | 0.81 | 5.6% | NYY | 107 | 23.9% |
| Flaherty | $10,300 | $9,600 | 3.80 | 10.15 | 2.91 | 1.18 | 7.5% | DET | 90 | 26.0% |
| Megill | $7,300 | $6,900 | 3.81 | 9.64 | 2.41 | 1.13 | 6.5% | SFG | 112 | 24.0% |
| Márquez | $9,000 | $8,200 | 4.03 | 8.82 | 3.03 | 0.83 | 4.7% | CHC | 90 | 25.6% |
| Berrios | $8,500 | $8,600 | 4.05 | 9.31 | 2.88 | 1.05 | 7.8% | CHW | 108 | 24.9% |
| Morgan | $6,800 | $7,700 | 4.27 | 8.94 | 1.99 | 1.99 | 11.0% | TEX | 76 | 23.4% |
TIER ONE: ACES — Burnes and Flaherty
Jack Flaherty sticks out like a sore thumb because he’s a legitimate ace and is facing a terrible Tigers team that strikes out a ton. They strike out more often than any other pitcher’s matchup on this slate. He’s also pitched six-plus innings in nine of his 13 starts, so he’s staying in if he’s rolling — and he should roll through Detroit tonight for a quality start, a win, and a shot at nine-plus strikeouts.
THE BAT has Flaherty projected for the most raw points and lower ownership on FD, but pretty high ownership on DK. Sucking the air out of the room is the 500-pound gorilla looming over this slate with another idiom that slips my mind.
Corbin Burnes is the best pitcher on this slate and it isn’t close at all. This season, he’s fine-tuned his control and been a friggin’ serial killer:
2.57 SIERA
12.40 K/9
1.63 BB/9
35.1% K-BB rate
0.35 HR/9
2.7% barrel rate
These are the only Cy Young digits on the slate. That said, we’re paying for it.
Burnes is $1,200 more than Flaherty on FD and $1,000 more on DK. Instead of facing the bum-assed Tigers in a pitchers’ park like St. Louis, Burnes has to face a strong Reds lineup in a hitters’ park like Milwaukee. So, there is added risk.
I don’t — personally — think this risk is enough to sway me from the best pitcher on the slate. Flaherty is a really good pitcher. But it would take a great pitcher or maybe 150% of Flaherty’s ownership to take me away from Burnes on either site in single-entry.
In MME play, there’s a decision to be made. I expect the field to spread ownership around to a lot of good pitching that we have on this slate, I’m taking a strong stance by going overweight on both guys. The field wants to have enough lineups to spread exposure. I want to counter that by being potentially overexposed to the two cleat-cut aces.
TIER TWO: THE DK SP2 — Márquez
Germán Márquez isn’t cheap in a vacuum, but he’s way too cheap for the skillset and situation. This is a Coors Field pitcher with only 0.83 HR/9 on a 4.7% barrel rate and near 9.00 K/9. This is a really good pitcher. Add that he’s facing the Cubs and their high strikeout rate against right-handed pitching and I DGAF how the wind is blowing; he’s the best SP2 play on DK.
That said, everyone is seeing this terrible Cubs dynamic and will jam him in, which forces us to call back to savings on Flaherty from Burnes. More importantly, it raises the necessity for us to not play Flahety-Márquez or Burnes-Márquez lineups too freely, as those will be the two chalk combinations. We can play them; we just need to stack off the board when we do.
And we don’t have to play those pairings. There is a wealth of pivots on this slate.
TIER THREE: PIVOTS — Morton, Megill, Berrios, Morgan
Charlie Morton is still a really good pitcher. Where he ranks on this slate among qualified pitchers:
3rd in SIERA
4th in K/9
4th in K-BB%
2nd in HR/9
5th in barrel rate
Morton faces a tough power matchup in the Yankees, but he neutralizes power. The key to this play is that the Yankees have a few guys who strike out a bunch and Morton has baked-in strikeouts. No one’s gonna play him.
Tylor Megill is more than just a background Game of Thrones character. He’s a pretty good pitcher with baked-in strikeouts, decent control, and strong power prevention, who can go six innings, if he’s rolling. The Giants are a really tough matchup, but Citi Field is a great pitchers’ park. There aren’t any good SP plays under $7,000, so we have to consider sprinkling him around.
José Berríos is probably the pitcher after Morton in a bad matchup that I’m considering most. The White Sox are about as bad a matchup as the Yankees, but they strike out more often. This is a guy who can go seven innings against anyone any given night. Remember that more innings equals more strikeout opportunities and, hell, we get fantasy point for innings, too.
Last and certainly least, we have to discuss Eli Morgan. He isn’t any damn good. He walks too many guys and is a launching pad when contact is made. But this is a great run prevention situation. The Rangers are worse than the Tigers and Cubs and we’re considering passing over Burnes for Flaherty and Márquez. We can save a lot of money in some lineups and get the nut matchup. Sure, it can blow up in our faces, but this is baseball.
Baseball is a risky game on which to make wagers of any sort. The temptation on a slate where there is really good pitching is to eliminate all of the high-risk situations as unnecessary. This is incorrect.
Tournaments are won by calculating when to embrace variance. Doing so at SP2 with a guy who struggles to prevent power because he can strike out a man per inning is totally fine. Especially on a slate where the cheapest guy we want to play is $8,200.

We are only a month into the “second half” but we are already seeing some pitchers turn their season around. I put it in quotes because it’s obviously not a pure 81/81 game split, but rather the halves are determined by the All-Star break. I’m sure some players use the time off to dig into their numbers and come up with a gameplan to improve while others likely just relax and enjoy the breather. These three arms have been markedly better since July and I wanted to investigate what changed to bring about these turnarounds.
Marco Gonzales, SEA
1H: 5.88 ERA/1.46 WHIP in 56.7 IP | 2H: 1.67 ERA/0.90 WHIP in 32.3 IP
While few fully believed Gonzales’s 2020 (3.10 ERA/0.95 WHIP) since it was just two months, he was still drafted for useful ratios over a good number of innings. At no point in the first half was his ERA below 5.00 and his 2.4 HR/9 was seeing him hit more waiver wires with each passing week. He opened the second half with a trip to Colorado which was sure to be a disaster given how his season was going to that point… so of course he put up a 5 IP/2 ER outing, notching his second win of the year.
