I don't think speed has ever been one of his strong points, so I'm not sure what happened in that particular game. Last year was his big breakout year, I think he hit almost .350 between high A, AA, and the majors. He also started showing some power for the first time in his career. He also tore up the Venezuelan League over the winter, and has been hitting like crazy this spring. Dude swings at almost every pitch he sees though. I think he walked 4 times in 140 at bats in the majors. I figure pitchers will eventually start working against that.
He also doesn't really seem to have a position. He came in as a really good defensive catcher, but I think there are concerns about his ability to be a catcher long-term because of his size (5'11" and about 250). In the minors they took him away from catching one entire season before putting him back and bouncing him between there and first base. He's supposed to play third this year, but he has pretty limited experience there, so we'll have to see how that goes.
