1. The flights of the balls are, completely the same...they are just mirror images. There are sliced balls to left field from LH hitters, and hooked balls from RH hitters. In RF, same balls, just from opposite handed hitters... sliced balls from RH hitters, hooked balls from LH hitters. The number of PAs by RH hitters in the AL last year was higher than by LH hitters, but not by a lot: 49467 to 42723. The number of balls put in play to RF and lF were very similar: 15268 to LF, 14762 to RF (hat tip to baseballref). If you look at putouts by RFers and LFers each year, they are very similar...I'm not going to do that research again, but we had this discussion a few years ago on BYTO and I am confident I remember that correctly. All of which means RFers and LFers are going to see a similar number of chances. There are quirky ballpark differences in RF and LF, but other than that, there just isn't much difference between playing one or the other. Better arm usually plays right. Personal preference and/or familiarity maybe. 2. I didn't say you wanted Arcia in right. I said you've called him a bad OFer unlikely to improve. So if, as you've stated, RF is more difficult, I don't understand why you are against moving him to left.
