Twins reliever Glen Perkins is a stat-head

7 Comments

Twins left-hander Glen Perkins is one of the American League’s best relievers and anyone who follows him on Twitter knows that he’s also a funny, interesting guy who likes to interact with fans.

And now thanks to this interview with David Laurila of Fan Graphs we also know that Perkins is into sabermetrics:

I like a lot of stats and go onto FanGraphs pretty much every day. I like FIP and xFIP, which give you an idea of whether you’re doing the right things. Not that it’s something you can control, but you know that if it’s down–and you keep doing what you’re doing–the balls are going to find fielders. If your FIP is one thing and your ERA is higher, they’re probably going to meet in the middle. My ERA this year started out high and came down to closer to what my fielding-independent is.

I didn’t get frustrated with my bad ERA. I had given up a couple of home runs and felt that maybe some balls were finding holes. You can’t start thinking, “Now I have to strike every guy out.” Understanding that things should even out gives me confidence in what I’ve done. [FIP] shows that I should be here, and not here.

Perkins also went on to make some interesting points about the issues with judging relievers by Wins Above Replacement and … well, you really should just read the whole chat.

And now I’m regretting not asking Perkins to come hang out at the annual SABR convention when it was in Minneapolis two weeks ago.

Mets pitcher Zack Wheeler will be placed on the 10-day injured list due to fatigue in his right shoulder, Newsday’s Tim Healey reports. The roster move is retroactive to July 12. Steven Matz will open up a two-game series in Minnesota, starting in Wheeler’s place on Tuesday.

As Healey notes, the soonest Wheeler can return is July 23, which would give him at most two starts ahead of the July 31 trade deadline. Wheeler has frequently been brought up in trade conversations as he can become a free agent after the season and the 42-51 Mets have been freefalling.

Wheeler, 29, owns a 4.69 ERA with 130 strikeouts and 34 walks across 119 innings of work this season.
