Pereira and Doyle both have the same 13.3% walk rate vs. LHP in the majors this season (small samples for both). EP K's a lot more (40% vs. 27%) while having a lower barrel% and hard hit% but better surface numbers. His .462 BABIP, a 90 point gap between his actual and expected wOBA, and a 30%+ HR/FB rate vs lefties suggests there's room for some regression in those numbers. In a weird coincidence, both guys have 43 ABs overall in AAA this year so at least their small sample sizes are easily comparable: Doyle: 17-43 with 5 2B, 2 HR, 8 BB and 19K Pereira: 10-43 with 1 2B, 4 HR, 6 BB, 15K Don't know enough about Doyle to speculate on if he made some changes while rehabbing at AAA, but he was super productive in his most recent stint there to end July: 10 for 21 with 3 2B, 1 HR, 2 BB, 4K. (Pereira was 4-25 with 1 2B, 1 HR, 2 BB, 10 K in his rehab stint around the same time). Pereira obviously took a bit to get going until his great day yesterday (2-11 since returning with 1 2B/HR, 0 BB, 7K) Doyle hasn't been back up as long but is 2 for 6 with a 2B, BB, and 2 K in two games. If they buy into the flashes with the bat and really believe in Doyle as a plus defender, it could work out. One assumes that must be the case given the cost. Hope they're right (though I also hope EP sneaks through waivers anyway). Wish the kid had options, this would bug me less if it was like a Junior Perez DFA instead.
