RF gets about 360 chances in a season and LF gets 300 (roughly 2 per game). RF has more difficult chances. CF gets 450 (3 per game) 2B 600, SS 650, 3B 450. 1B gets 1400, but over 1100 of them are catching a thrown ball. Overall, the defense creates about 19 of the 27 outs in a game. OF gets 7 and the infield gets 12 (averages).
I think spin might be the answer for why he moved from 2B to RF, but long-term he needs to figure out spin in LF.
