When the Yankees hired Larry Rothschild away from the Cubs to be their new pitching coach yesterday, Ben noted that his staffs tend to boast high strikeout rates. Earlier this summer a poster on the FanGraphs Community blog looked at exactly that, and found out that pitchers did in fact improve their strikeout rates with Rothschild, close to 2.5% as a group. But what about walks? Another Cubs Blog tackled that a few days later and found that yep, pitchers improved their unintentional walk rate with Rothschild as well. More strikeouts and fewer walks is a great recipe for success.

The Yanks as a group struck out 0.62 fewer batters and walked 0.19 more (per nine innings pitched) in 2010 than in 2009, with CC Sabathia‘s rates taking a hit in particular. With any luck, Rothschild will help get the staff back into strikeout mode, which would be a tremendous help.
