Free Agent Faceoff: Back Of Rotation Starters

With another quiet day turning into an even less eventful evening, I thought we’d spice things up with a look at a particularly interesting segment of the free agent market: innings-eating veteran starters.

Sure, I’m joking. Almost by definition, a back-of-the-rotation innings eater is not a very exciting pitcher. But, then again, perhaps there is something to the idea that this corner of the universe has more intrigue than it might seem at first glance.

Targeting top-end players is fairly straightforward, whereas figuring whether to pursue one or another back-end arm involves much more careful parsing to find value. The fact that most such pitchers sign for short-term deals means that clubs must be right on the player in the immediate term; there is no time to fix them for the future. And then there is the fact that the performance of these players matters a great deal; unlike a utility man or reliever, innings-eating arms are expected to occupy full-time roles. Racking up losses because your number 4 and 5 starters are not competitive is a great way to dig a hole in the standings.

The potential impact of this type of player is evidenced by the list of the best durable, veteran starters still available, several of whom played for contenders in 2014 and one of whom even pitched in the World Series. For better or worse, all of the players listed were allowed to throw at least 150 innings last year, creating plenty of opportunity to add or subtract value.

Kevin Correia: The results are not usually that exciting, but Correia has logged at least 100 innings in every season since 2007. He delivered an average of 178 innings of 4.19 ERA pitching over 2012-13 before suffering through a rough 2014.

Aaron Harang: Last year’s shining example of the importance of choosing your innings eaters carefully, Harang put up 204 1/3 frames with a 3.57 ERA. Sure, there’s a lot baked in there other than his pitching, but the bottom line is that Harang rated amongst the game’s fifty best starters in terms of preventing runs and among its 25 best in logging innings.

Roberto Hernandez: The results haven’t been there for Hernandez, and there is not much silver lining given that he has seen a steady decline in fastball velocity. But he is quite a steady groundball inducer, and showed enough that the Dodgers traded for him and gave him nine starts down the stretch.

Kyle Kendrick: At some point, 199 innings is 199 innings, and that’s what Kendrick delivered last season. He is also a fairly youthful 30 years of age, and is not far removed from producing serviceable results.

Ryan Vogelsong: Though his peripherals are somewhat less promising, Vogelsong has posted pretty darned useful bottom-line results in three of the past four seasons. And he had enough in the tank to run his fastball up to the mid-90s in the postseason.

Chris Young: ERA estimators view Young’s 3.65 earned run mark last year as a mirage, but then again he has always outperformed his peripherals. It had been quite some time since the towering righty had handled a full season in a rotation, but Seattle happily converted his 165 innings of work into a 12-9 record in 29 starts.
