This season, Red Sox left fielders as a unit are 15th in the league with a .739 OPS, and haven’t been very good with the leather. Brock Holt has been trying to fill in for Chris Young’s .288 TAv, but neither his .259 mark or Bryce Brentz’s .257 TAv have come close to replicating that. It’s been a long, gradual slope downhill for that position.
That’s where Benintendi comes in. The Red Sox probably didn’t want to bring him up this early, but with no clear options available to them and Chris Young still a ways off, it was worth a shot. He immediately gives the Red Sox an outfielder who can actually play the position. Holt’s value comes in playing multiple positions acceptably, not a single one well, and Brentz, well……let’s just say fielding isn’t his strong suit. Benintendi has much better chops than both of them in the field.
Speaking of Holt, Benintendi’s call-up might have shown that the Red Sox have finally learned their lesson with Brock Holt in the second half. See, he’s usually pretty good for three months, give or take a couple weeks. Once the second half starts, he’s not so great:
I endorse this article by Baseball Prospects; What's troubling is John Farrell fully endorsing Holt as the starting LF in April. Maybe he just didn't mention that it's only good until the All Star break.
