Bill James thinks Sabermetrics has overrated ground ball pitchers

34 Comments

Rob Neyer expounded on a Bill James piece (here, behind a paywall) at SB Nation in which James says that proponents of Sabermetrics have “horribly overstated” the case for ground ball pitchers. He cites a handful of elite pitchers — Tom Seaver, Bob Gibson, Randy Johnson, Justin Verlander, among others — and points out that they weren’t very good in the ground ball department. He also cites a handful of ground ball pitchers — namely Chien-Ming Wang and Brandon Webb — who have had serious issues with injuries.

What I have never understood about ground ball pitchers, and do not understand now, is why they always get hurt. Show me an extreme ground ball pitcher, a guy with a terrific ground ball rate, and I’ll show you a guy who is going to be good for two years and then get hurt.

They’re great for two years, and then they blow up. Always.

The one exception to James’ analysis is, of course, Derek Lowe, who made at least 32 starts in each season from 2002-11.

I don’t think we have the capability to make a strong conclusion one way or another based on the quality of data we have right now. Presently, there is no differentiation between types of batted balls. There is a vast difference between a dribbler down the third base line and a screamer up the middle. FanGraphs differentiates between infield and outfield flies, which has helped us to better appreciate pitchers like Matt Cain and Jonathan Papelbon. No such distinction is made for ground balls.

There is no way of knowing now, of course, but there may be a link between injury risk and the types of ground balls a pitcher induces. Basing analysis on data that utilizes binary qualitative groups — “on the ground” and “not on the ground” — is far too broad.

(Tip of the cap to David Schoenfield at ESPN Sweet Spot for directing me to Neyer and James.)

Per ESPN’s Jesse Rogers, Jake Arrieta‘s agent Scott Boras says they’ll discuss a potential contract extension with the Cubs when they meet in January to hammer out arbitration figures.

Arrieta, 30, is entering his third and final year of arbitration eligibility after earning $10.7 million in 2016. The right-hander followed up his Cy Young Award-winning 2015 campaign by going 18-8 with a 3.10 ERA and a 190/76 K/BB ratio in 197 1/3 innings during the regular season. Arrieta pitched well in the postseason, helping the Cubs win their first World Series since 1908.

While Boras clients tend to go to free agency, it’s not always the case. Stephen Strasburg inked a seven-year, $175 million extension with the Nationals earlier this year.

Report: Koji Uehara close to signing with the Cubs

Evan Drellich of the Boston Herald reports, citing a source as well as Nikkan Sports, that reliever Koji Uehara is close to signing a one-year, $4.5 million deal with the Cubs.

Uehara, 41, finished the 2016 season with a 3.45 ERA and a 63/11 K/BB ratio over 47 innings. He missed some time in the second half with a strained right pectoral muscle. When Uehara returned from the disabled list on September 7, he tossed 11 scoreless innings with 12 strikeouts and two walks through the end of the regular season. So there’s at least some evidence, albeit in a very small sample size, that Uehara has stuff left in the tank.

The Cubs recently acquired closer Wade Davis from the Royals. Uehara would join Hector Rondon, Pedro Strop, Carl Edwards, Jr., Justin Grimm, and Mike Montgomery in what is once again a very deep bullpen.
