OF George Springer (Arizona Fall League)
Springer had a particularly good fall campaign. In 21 games, he hit .286/.412/.600 with four doubles, three triples, four home runs and five stolen bases. His OPS was fourth in the league and his SLG was third in the league. He was the only Astros winter league player with an OPS over 1.000.
SS Jio Mier (Arizona Fall League)
Jio Mier was designated as a taxi squad player (only intended to play twice a week), but ended up working his way into regular playing time later in the season and played some third base as well as shortstop. In 17 games, he hit .297/.333/.422 with eight doubles. This was particularly good to see since Jio missed a large chunk of the season due to injury. Also, it's harder to discount Jio's good stats at Lancaster this season when he was able to repeat good numbers against some of the best players in the minor leagues.
2B Jose Altuve (Venezuelan Winter League)
BREAKING NEWS!!! Jose Altuve can hit. What else is new? .336/.406/.441 with 10 doubles, a triple, a home run and eight stolen bases in 35 games sounds about right.
2B Enrique "Kiké" Hernandez (Puerto Rican Winter League)
I was very pleased to see Kiké build on his 2012 comeback season. In 39 games in the regular LBPRC season, he hit .320/.379/.469 with 12 doubles, two triples, two home runs and four stolen bases. He was sixth in the league in BA, 13th in OBP, eighth in SLG and fifth in OPS. Watch out Altuve, Kiké is catching up to you (and he's just as big a hit with the fans!). Although he primarily played second base, he also played several games at third.
OF Brandon Barnes (Venezuelan Winter League)
And speaking of fan favorites, Brandon Barnes quickly wowed the LVBP fans with his style of play. Brandon only played in 28 games and was back in the States in time to spend Thanksgiving with his wife and daughter, but the Caracas crowd had already adopted him as one of their own. He hit .292/.353/.491 with three doubles, three triples and four home runs.
Others of Note
2B Jose Martinez hit a healthy .287/.358/.401 with seven doubles and four home runs in 46 games and ranked in the top 20 in BA and OBP in the LVBP. C Carlos Corporan hit .293/.377/.466 with four doubles and two home runs in 23 games in the Puerto Rican Winter League regular season. C Carlos Perez hit a more than respectable .324/.398/.500 with 13 doubles and two home runs in 32 games in the Liga Paralela. And last, but certainly not least, C Luis Alavarez not only hit a robust .340/.398/.474 in 28 games in the Liga Paralela, he also went 6-for-7 with two home runs, five RBI and three runs scored in the playoffs as his Magallanes team won the Liga Paralela crown.
