We're at the point where I think the only Astros player who may still be playing in the winter league finals is Aneury Rodriguez. He pitched 4 innings on Saturday and 4 innings on Tuesday so as long as he didn't wrap things up early to come home, he'll probably be pitching again this weekend for Escogido. (Escogido leads the best of 9 finals 3-2 over Aguilas after losing to Aguilas last night.)
Aneury Rodriguez has had a very strong winter. During the regular season for Escogido, he had a 2.48 ERA, 0.857 WHIP and 5BB:32SO over 8 appearances (32.2 IP). During the finals, he has a 1.56 ERA, 1.269 WHIP and 3BB:13SO over 17.1 IP so far.
