Finding Borowski’s Replacement

The DL bound Joe Borowski has apparently had soreness in his right triceps that the Indians staff decided to let him pitch through for weeks. I guess that helps explain his 18.00 ERA and super slow fastball.

Despite leading the AL with 45 saves last year, he also led it in blown saves with 8 and his ERA of 5.04 was by far the highest of any closer last year. He did have pretty decent peripherals though, with a K/9 of nearly 8 and a BB/9 of 2.33. His season was mainly marred by an extremely high .348 BABIP and a pretty sub par LOB% of 68.4%. Typically both of these will regress toward the league averages in following years.

The main problem with Borowski is that he’s a bit of an extreme fly ball pitcher and will be prone to giving up home runs. Last year he allowed 9, which was just 4 home runs shy of Al Reyes‘ reliever leading 13.

So the question is, if Borowski is out for an extended period of time, who will get his job?

Rafael Betancourt is the obvious choice. He had a gaudy K/BB of nearly 9 last year, and a 1.47 ERA in 79+ innings of work. He also entered games in high leverage, non-save situations last season with a gmLI of 1.78. Borowski entered games in slightly higher leverage situations with a gmLI of 1.94. Even though he has an ERA over 5 this year, his strikeouts and walks are almost identical to last year, so there’s probably not much to worry about.

Rafael Perez had nearly as great a season as Betancourt did in 2007. He struck out over a batter an inning and had a BB/9 of just 2.23, which led him to a career low 1.78 ERA. This year his ERA is over 8 and he’s allowed a few more walks then he should. But, he’s only pitched 4 innings this year and allowed his only 4 earned runs in one of his appearances so definitely take those numbers with a grain of salt.

Masa Kobayashi has had a solid season so far with a with a 2.08 ERA and 3 strikeouts and 1 walk in 4+ innings. He amassed over 200 saves in Japan, and technically has more career saves than anyone on the Indians. Kaz Sasaki and Takashi Saito had zero problems stepping right into the closer roles when they first arrived in the majors.

Finally, there’s Jensen Lewis who last year had a 34/10 strikeout to walk ratio in 29 innings pitched with a 2.15 ERA. This year, it appears to be more of that same excellence, though his K/9 is down to 8 from 10, but small sample size and all that….

Here’s how they’ve been utilized this year so far, according to gmLI:

Joe Borowski – 1.86
Jensen Lewis – 1.61
Rafael Perez – 1.48
Rafael Betancourt – 1.27
Masa Kobayashi – 0.23

Borowski should have the highest gmLI as the closer and does. Oddly enough, Jensen and Perez have entered the game in higher leverage situations than Betancourt has, despite his reputation as a fire putter-outer. Kobayashi is clearly not used in confidence, but there are only so many high leverage situations and he just hasn’t had the opportunity with such an overall excellent bullpen.

Judging from tonight’s game, Betancourt was being “saved” to close out the game and was not utilized in a tie game in the 8th. Nor was he used in the 7th with the Indians up 2-1 and the Red Sox threatening with a man on 1st and 2nd.

So for the moment, it looks like Betancourt is going to get to close out games, but the Indians have a pretty stellar bullpen and I think if needed any of these guys could handle the closer job.

When Borowski comes back and if he’s healthy, chances are he’ll be given a shot to reclaim his role as closer. And while he’s not as bad as he’s often made out to be, he really is one of the worst options in what appears to be a very stacked Indians bullpen.
