Plenty of compelling bullpen activity around the major leagues on a busy Sunday afternoon…

Koda Glover was brought into an existing eighth inning with a 6-4 lead, two outs, and a runner on second. He retired Jed Lowrie to end the inning, then the Nationals proceeded to score five runs in a long top of the ninth. Despite the 11-4 lead and lengthy half inning, Glover came back out for the bottom of the ninth, and he allowed four straight singles and a walk before being replaced by Shawn Kelley with the bases loaded, no outs, and two runs already in. After retiring Rajai Davis on a shallow fly ball, Kelley served up a grand slam to Matt Joyce that made it 11-10 Nationals. Kelley retired the next two batters he faced to secure the victory. When it was all said and done, Glover was charged with five earned runs in 0.1 innings, and Kelley was charged with one earned run in one inning.

Despite today’s craziness, Glover has brought much-needed calm to the Nationals bullpen as of late. He has four saves since May 24, and before today, he had recorded saves in four straight appearances. This was the first time Glover has allowed a run in 10 appearances since he landed on the disabled list with a left hip impingement in late April. Even with today’s meltdown, Glover has a 1.74 FIP and 3.21 xFIP on the season. A 3.21 xFIP is hardly something to scoff at, and it seems as if the Nationals have finally found their ninth-inning man (although it remains probable they’ll target bullpen help before the trading deadline). The home run Kelley gave up was the seventh he’s allowed in 15 innings this season, and overall, he has a 5.40 ERA and 5.37 xFIP. As such, he has been surpassed on the grid by Matt Albers, who boasts a strong 1.29 ERA and 3.14 xFIP in 21 innings this year. Read the rest of this entry »

As a RotoGraphs reader, I’ve always enjoyed Joe Douglas’s “Buying Generic” series. In past articles, he has compellingly compared “generic” players like Ryon Healy, Logan Forsythe, and Justin Bour to “brand name” ones like Jake Lamb, Jason Kipnis, and Carlos Santana.

The fantasy relevance of the exercise is obvious: Buying generic allows owners to acquire players cheaply and with relative ease, instead of paying a premium (whether in a trade or in a draft or auction) for a brand-name player.

For today’s comparison, we’re going to analyze two players who have played in parts of the last three seasons, but neither has eclipsed 350 plate appearances in any one year. Both appear on their way to full-time jobs in 2017 and beyond.

Here’s how Mr. Generic and Mr. Brand Name have fared since 2015:

Plenty of bullpen-related news and notes on a busy Sunday afternoon. A few noteworthy items from Saturday are mixed in as well…

• With a 5-3 lead against the Nationals, Brad Hand struck out one in a scoreless eighth, and Brandon Maurer retired Trea Turner, Daniel Murphy, and Anthony Rendon consecutively in the ninth to secure his sixth save of the season. Maurer was temporarily removed from the close’s role, during which time Hand filled in respectably, but at least for today things went back to normal. Although Maurer has a 6.52 ERA on the season, his peripherals suggest he’s been much better than that. He has an excellent 2.59 FIP and 2.66 xFIP on the season thanks to the fact that he’s only allowed four walks and two home runs in 20 innings this year, to go along with 23 strikeouts. While Hand is an excellent reliever in his own right, Maurer still appears to hold the edge in save opportunities, at least for now. If Maurer falters, however, it appears that the Padres are willing to pivot to Hand at a moment’s notice. As such, Hand worth targeting for those speculative on saves, and he’s certainly worth owning in holds leagues, as he’s on of the better set-up men in baseball.

I wanted to take a break from my Effective Velocity research, and so, in honor of Anthony Rendon, I decided to take a look at streaky hitters. Before this season, I did not have a perception of Rendon as streaky. But so far this season, he has produced 5 of his 7 total home runs, 7 of his 21 total runs, and 15 of his 28 total RBI in just two games. That’s insane. It may not mean anything in this case; however, it makes intuitive sense that some hitters would be more consistent than others. And beyond even the desire to roster consistent hitters over streaky hitters in weekly formats, I think it is at least worth exploring whether it is possible to identify hot and cold streaks as they are happening and make start-and-sit decisions with them in mind.

The first step toward that goal is defining what hot and cold streaks are. Rendon probably isn’t the best example of that. In general, I think of a hot hitter as one who produces well above his typical level of production for an extended period. As a starting point, I decided to look at players who produced a wOBA over seven consecutive games or more that was either 110 points above their seasonal line (hot) or 110 points below their seasonal line (cold). That 110-point threshold is fairly random, but it is based on the difference in the glossary markers for an excellent and awful player over a full season.

Back in early April, I wrote a Five Under 50% post in which I implored fantasy owners to invest in the likes of Nick Franklin and Dan Altavilla. I urged readers to steer clear of Marwin Gonzalez, and promised that Edwin Diaz’s job was as safe as they come.

Naturally, Franklin has a 38 wRC+, Altavilla has a 6.60 ERA, Gonzalez has a .419 wOBA, and Diaz is no longer the Mariners closer. Sorry about that.

Before you quit reading this post because, really, why should you trust me, just know that my predictions weren’t all terrible. I also forecasted success for Scott Schebler (.365 wOBA), Mark Reynolds (.419 wOBA), and Ryan Zimmerman (.469 wOBA), who have been among the best hitters in baseball this year.

Not every gamble will pay off. But when it does, it can transform a fantasy team. It’s been about a month and a half since my last Five Under 50% post, and with renewed confidence, I’m prepared to do it again now.

Below are five (actually seven; I cheated) players owned in less than 50% of Ottoneu leagues whom I think may be worth an add in most leagues. There’s no need to jealously yearn for these players later when you can win them now for pennies on the dollar.

To date, all of my Effective Velocity research has centered on pitchers. That is probably because the story that introduced me to the concept of EV focused on Trevor Bauer in the narrative, which tied the concept to the position in my mind. However, the more I’ve thought about it over the last several weeks, the more convinced I’ve become that catchers would likely share the responsibility for their pitchers’ EV adherence. After all, for every Bauer, there are probably dozens of pitchers who rarely if ever shake off the signs their catchers throw down. Meanwhile, the concept of EV falls into the game-calling strategy bucket that we more typically associate with catchers than pitchers.

The research I’ve done on Effective Velocity to date has led to some interesting examples that in many cases suggest the strategy has an impact on pitcher success.  But to be able to really take advantage of that implication, I felt I needed to create an ERA estimator that would apply to all pitchers.  If that metric were more predictive of future performance than our current best ERA estimators like FIP, then fantasy owners could systematically use it to make better decisions based on pitchers’ adherence to the philosophy of Effective Velocity.

It’s a well-established fact that AT&T Park is one of the worst ballparks in the major leagues for offense. That’s why, despite putting up a 132 wRC+ over his last 1,500 or so plate appearances, Brandon Belt is not a very valuable fantasy first baseman. It’s also why Buster Posey, a catcher with a career 136 wRC+, has never really been worthy of a top-10 pick on fantasy draft day.

In recent years, however, a new and troubling trend has emerged for the Giants offense. While the league has been on an historic home run tear the last year and a half or so, the Giants have not kept up. In fact, they’ve done the opposite: they’re hitting more ground balls (and fewer fly balls) than just about any other team in baseball.

Ground balls are almost always worse than fly balls, even for a team that plays in a cavernous ballpark like the Giants. Since 2014, Giants hitters have a .245 AVG, .263 SLG, .223 wOBA, and 45 wRC+ on ground balls at home. On their fly balls at home, however, they have a .226 AVG, .598 SLG, .332 wOBA, and 119 wRC+ since 2014.

While the team batting average is actually higher on ground balls, the slugging percentage, wOBA, and wRC+ are so, so much worse. This is strong evidence to the effect that even a team that plays in an extreme pitcher’s park is not better off hitting ground balls — flies seem to be indisputably better no matter what.

Yesterday, I discussed 10 hitters whose FB% has increased the most compared to last year. So now let’s check in on the other end of the list — the hitters whose FB% has declined the most versus last season. These hitters may be in danger of disappointing in the home run department.

At the time of this writing, there are 37 major league hitters with a wRC+ of 150 or higher. There are the usual suspects: Bryce Harper, Mike Trout, and Nolan Arenado are on the leaderboard to no one’s surprise. There are exciting young prospects, including Mitch Haniger, Aaron Judge, and Joey Gallo. Then there are unexpected names like Eric Thames, Cesar Hernandez, and Robbie Grossman.

Lengthy articles could be, and have been, written about any of the players above. One player who hasn’t received much publicity despite some relatively prolonged success is Grossman.

He checks in with a 158 wRC+ in 67 plate appearances so far this year. Steamer projects a .322 wOBA and 99 wRC+ for the rest of the season (ROS), and that projection puts him just a few ticks behind his highly-touted teammate Max Kepler. Although Kepler is three years younger and may have a higher ceiling, the point is that name recognition can play a pretty big role in how we analyze players.

Also, Grossman used to be bad. From 2013 to 2015, he had just a .281 wOBA and 77 wRC+ in 202 plate appearances against left-handed pitching, despite being a switch hitter. Since 2016, however, Grossman has a .417 wOBA and 166 wRC+ in 170 plate appearances against lefties. Even with his early-career struggles against lefties, Grossman now has a lifetime .344 wOBA and 118 wRC+ against them. Read the rest of this entry »
