Glen Perkins, stat-head closer

3 Comments

Parker Hageman at Twins Daily has an excellent article about Twins left-hander Glen Perkins, who went from injured, mediocre starter to excellent late-inning reliever and now full-time closer.

Perkins talked about how he started getting into sabermetrics when he was hurt in 2010 and has embraced statistical analysis ever since:

I didn’t get into any advanced stats until 2010 when I was in Triple-A and struggling. It was a combination of [Ryan] Vogelsong and when Brandon McCarthy came back and I started to hear about those guys who were injured or unsuccessful and then they adjusted their pitch selections and focused doing different things. That got me thinking, maybe it’s something I should do.

Since then Perkins has 132 innings with a 2.52 ERA and recently signed a $12 million contract.

There’s also some interesting stuff from Perkins about the unreliability of Pitchf/x classifying his pitches and whether or not he believes the numbers when they show he’s getting squeezed by umpires. Definitely worth checking out the whole article. Good stuff.
