Fangraphs looks at Votto:
For his career, 45.3% of the pitches Votto has been thrown have been in the strike zone, though that number has been dropping for each of the past few years as pitchers have figured out how good he really is. This year, only 36.2% of the pitches Votto has seen have been strikes, the lowest total of any hitter in baseball. Rather than getting frustrated by the lack of pitches he’s being given to hit and expanding his zone, Votto has actually gone the other way – he’s cut his O-Swing% to 23.1%, down from 29.9% last year.
