Likely? If only there were a place to look such things up. http://www.baseball-reference.com/leagues/split.cgi?t=b&lg=AL&year=2014 League-wide, batters had a .341 BA on first pitches put in play, if I'm reading that correctly. Overall BA was .253. League wide, it looks like about 10% of PA were decided on the first pitch. For Mauer, it was only 5%. So we're not imagining that. However, the ratios of 1-0 versus 0-1 pitches look about the same for Mauer as for the league, so (again if I'm not misinterpreting) it's not as though Mauer is just standing there looking at strike one, PA after PA. It's really unclear from the stats that swinging more at the first pitch will solve anything. Pitch recognition and selection would seem more the issue, based on the higher number of strikeouts and the way he looks when making those strikeouts.
