Bunts and pitchers’ fielding

Beware of trying to bunt on Kenta Maeda.

There was a nice blog post the other day on Baseball Labo about fielding bunts and the huge difference in the record between last year’s Golden Glove Winners, Kenta Maeda of the Hiroshima Carp and Chihiro Kaneko of the Orix Buffaloes. While it didn’t go on to question Kaneko’s award — which it could have, it pointed out that the Buffaloes ace never defeats a sacrifice bunt by getting the lead runner.

In 51 sacrifice situations between 2010 and 2014, Maeda fielded 51 bunts and got one of the lead runners 11 times, for a Japan-best 21.6 percent. Kaneko, on the other hand had fielded 48 such bunts and never prevented the runner on first from reaching second.

Before last year’s Golden Glove voting, I had few tools with which to appraise pitchers — something that was annoying ever since voters handed the Central League’s Golden Glove in 2011 to setup man Takuya Asao, a strikeout pitcher who fielded a grand total of 16 balls that season. But since the sites I scrape to get my play-by-play data have noted bunt attempts since 2012, we can have perhaps a better sense of who the best fielding pitchers in NPB are.

The data set does not have base-out situations, so we are limited to total number of bunts fielded, the number of bunts in which no out is recorded and the number of sacrifices credited.

Since 2010, opponents have been credited with sacrifices on 81 percent of the bunts against Maeda which is among the best. But his teammate, right-hander Yusuke Nomura has allowed a sacrifice rate of 70 percent, the best in NPB. Considering both pitchers have allowed runners to reach safely on bunts (about 5 percent),  one might be tempted to think Nomura and his .985 fielding percentage would give him the edge over Maeda and his .939 fielding percentage.

Hiroshima’s Yusuke Nomura is not known for his fielding, yet.

Yusuke Kikuchi of the Pacific League’s Seibu Lions is also a candidate for NPB’s top fielder, with a no errors over the past four seasons, one bunter reaching safely in 44 attempts and a sacrifice rate of .84.
