Actually, place his BABIP from last year at his career average of .295, and it takes his batting average down to .287, which is extremely consistent with his career average of .275.
Total Hits (189) less HR (28) = 161
Total AB's (589) less HR (28) less K's (82) = 479
Multiply .295 (career BABIP) * Total AB's for BABIP Purposes (479) = 141 Hits, a difference of 20.
Take 20 hits off of his total hits column (189-20 = 169) and divide by the 589 and you get .287.
To put this into perspective, to go from .275 to .287 in 589 AB's, it requires only 7 more hits. That's miniscule.
If we are going to debate whether or not a player can affect his BABIP on command solely by motivation, then we're just going to agree to disagree. There are plenty of players who receive bonuses for achieving offensive goals, which provides them with plenty of motivation and you don't see their BABIP fluctuating significantly in bonus induced seasons.
