Reliever Efficiency

and Game Notes

In the Twins run of success over the past six or seven seasons, one constant has been the effectiveness of the bullpen. From Eddie Guardado and LaTroy Hawkins to Pat Neshek and Joe Nathan, the Twins have had some really strong bullpens that could be counted on. But it was more than those guys, there was always a group of four or five guys in the bullpen who just got the job done. Names like Tony Fiore and Juan Rincon, Matt Guerrier or even Hector Carrasco, Mike Jackson and Bob Wells. Getting the job done on a nightly basis is really important for a team that does not typically score a lot of runs and gets good starting pitching. The Twins bullpen has been a huge reason that the Twins have outplayed their Pythagorean Number over those years.

Last year when I did monthly grades, I started showing a statistic that I called Reliever Efficiency. Simply put, I look at the box scores and situations of each game played and look at whether or not each relief pitcher got his job done. For a closer, his job is to get a save and pitch well. An eighth inning set up man could be brought in with the bases loaded and a two run lead. If just one of the inherited runners score, he got his job done. Maybe Brian Bass comes into the game in the 2nd inning and gets the team to the 6th inning. Even if he gives up two or three runs, he does his job on that day. On the other side, a lefty specialist could be called upon to get the other team's top lefty hitter out with runners on 2nd and 3rd and two outs. If he gives up a two runs single, he didn't do his job on that day even if he gets the next guy out and his line score says 1/3 of an inning and no runs scored. Or, how about a pitcher comes in to start an inning. He gives up a hit and two walks but no runs... did he do his job? I don't think so. 

Reliever Efficiency is a debatable statistic. It's something I made up. It's something that isn't necessarily consistent from person to person. What I consider doing a pitcher's job (or not) may be slightly different that what you consider doing (or not doing) his job. So of course these percentages are subject to debate, but I think in general, it can tell a story. My main reason for it is because I think that ERA is vastly overrated for relievers. If a reliever has one of those games where he faces six guys and gives up three hits, a walk, hits a batter and all six score, his ERA will skyrocket. Even if he has ten or fifteen straight perfect innings, his ERA will still be high, so I don't think it's a good number to look at when in reality, he has done his job 10/11 or 15/16 appearances. So, take the statistic (a simple equation showing successful appearances divided by total appearances) for what it is worth. I do happen to think it's more valuable than ERA.

Why am I showing this today? Well, of late, there has been talk about how poorly Juan Rincon has pitched, not only this season, but really the last two years. Some think that he has actually not been too bad, so I quickly looked through Rincon's game log to see how he had done in this category. Last night, I actually went through the box scores from each of the Twins games through last night's loss and graded each relief pitcher in each game. They got either a G (for Good outing) or a B (for Bad outing). I think what I found is that this year's bullpen has definitely not been as consistent and trustworthy as it has been in the past. There are several reasons for that which I will talk about later, but first, let's take a look at how the Twins relief pitchers have done to this point:

*Through the Game played on May 21st.

Name April Good April Bad May Good May Bad Total Good Total Bad Reliever Efficiency
Joe Nathan 10 1 6 1 16 2 88.9% (16/18)
Pat Neshek 10 3 0 2 10 5 66.7% (10/15)
Matt Guerrier 7 4 5 4 12 8 60.0% (12/20)
Dennys Reyes 9 3 4 5 13 8 61.9% (13/21)
Juan Rincon 6 3 3 6 9 9 50.0% (9/18)
Jesse Crain 5 2 3 5 8 7 53.3% (8/15)
Brian Bass 4 3 5 1 9 4 69.2% (9/13)
Bobby Korecky 1 1 3 2 4 3 57.1% (4/7)
TOTAL 52 20 29 26 81 46 63.8% (81/127)

 So, what do we see here? First of off, overall, this bullpen has been bad. But looking specifically through 19 games in May, the bullpen has been horrible. Here are a couple of notes:

So, when Scott Baker comes back to the rotation, the Twins really have a couple of options. First, they could option Kevin Slowey or Glen Perkins to AAA. Option Number 2 is to move Boof Bonser (who is out of options and certainly would be claimed) to the bullpen. If that is the answer, then something needs to give in the bullpen. Brian Bass could be sent down, but he would have to clear waivers first. I don't think he would, and I don't think they should try it. Bobby Korecky could be optioned to Rochester. Jesse Crain could be optioned to Rochester. But again, my thought is that the Twins should eat the remainder of Juan Rincon's contract and Designate him for Assignment.

Those are the options for when Scott Baker comes off of the DL. Then realize that at some point Francisco Liriano will come back to the starting rotation and a second move will have to be made. Fortunately those are decisions that do not need to be made yet, and it is possible that by that time, there could be an injury or someone will make the choice obvious.
