Darrell Rasner’s numbers with various catchers

by on Apr.26, 2010 @ 2:05 pm, under NPB

Unlike the States, catchers tend to have a greater responsibility in Japan.  If a pitcher gets shelled, they're part of the reason.  Likewise, if a pitcher does well, it's usually because they did a good job leading the pitcher.

Darrell Rasner hasn't found a lot of success in Japan.  Rasner currently owns a 6.11 career ERA which works out to 71 earned runs allowed over 104.2 innings of work.  He has faced a total 469 batters and given up 122 hits (13 homers) and walks 32 for a 1.47 WHIP.  His BB/9 works out to 2.75 and his SO/9 to 5.7.  Both of these numbers are actually higher than what he was putting up back in States (1.72 BB/9 and 5.05 SO/9 in the Majors).

A newspaper article recently pointed to Rasner's catcher as being a reason for the success he found during his most recent start that ended in a complete game victory.  While I'm still on the fence with regards to how important a catcher is to the relative success of a pitcher, I thought it might be interesting to provide a table of catchers that have caught Ranser since he signed on with the team last season.

Catchers that have caught Rasner since 2009

Player W-L G IP BF NP H HR SO BB/HBP R ER ERA
Shima 2-6 10 50.0 232 1024 63 5 27 25 36 36 6.48
Fujii 1-2 4 21.0 94 350 27 4 16 3 21 20 8.58
Nakatani 1-2 4 24.2 108 419 26 4 17 9 14 13 4.74
Ino 1-0 1 9.0 35 126 6 0 6 3 2 2 2.00
Totals 5-10 19 104.2 469 1919 122 13 66 40 73 71 6.11

So, just how important is a catcher to a pitcher's relative success?

    I would say that the start with Ino was more of an outlier than anything else. Unless the catchers are telling Rasner to lob 80-85 MPH fastballs down the middle of the plate, I think it’s quite a stretch to blame them. He had a 5.52 ERA in yesterdays game, and his ERA probably would’ve been higher if not for Ino’s numerous throwing errors.
