Villar has shown some life of late. Hitting .280/.366/.402 in August, now up to .268/.369/.361 in 49 games at OKC, with 34 Runs, 29 BB, 57 K, 22 SB, 6 CS. Somewhat bizarrely has only hit 2 doubles.
In the field, he's made 6 errors, for a very decent .969 FLD% (2014 AL average is .973), so he looks to be continuing his improvement there. Despite his forgotten-man status, he won't turn 24 until next May, so perhaps there's hope for him yet.
Santana is also ending strongly. Had 2 hits, including a HR, and 3 BB last night to bring his numbers up to .302/.390/.485 for the season, with 16 HR and 79 RBI (along with 141 Ks...) in 117 games. August has actually been his best month - a terrific .383/.508/.660 with 19 RBI in just 15 games, and a much better 14:16 BB/K ratio. Domingo just turned 22 a few weeks ago. Most teams would be ecstatic with those numbers from a kid so young in AAA.
