he's still extraordinarily patient. 4.3 P/PA is in line with 2010 and 2011, but down from the 4.5 / 4.6 he had from 2005 to 2009. His BB% is a tick below his career average (11.5% v. 12.1%), but the drop in Ks is dramatic, as LostY says.
Looking at his BR page, his swung at strikes are at a career high (68%). the next closest year is 2010 (67%) while last year was 64%. First pitch swing % is also like 2010 and at his career high (19%, v. career avg. of 15%). Strikes looking declined this year 4% and is closer to 2010. 2011 more closely resembles 2007 - 2009.
