"I'm definitely excited," he said. "This is why you put in all the hard work, to get to this level. I think it was beneficial for me to go down to Oklahoma City and work on some things and play every day and do all that stuff to get my confidence and rhythm back. I feel good. I wish George wasn't hurt. A lot of people are in that boat, but it's part of the game, and so I'm going to try to step in and do what I can to help the team win."
Krauss figures to get most of his playing time in left field, starting against right-handers while L.J. Hoes will start against lefties. Krauss can also play right field, first base and serve as the designated hitter. He hit .173 with four homers and 14 RBIs in 39 games with the Astros earlier this year and was hitting .289 with five homers and 38 RBIs in 42 games at Oklahoma City.
"I became more aggressive at the plate," he said. "I was just trying to get my pitch and not miss it. For a while there I was doing pretty well. I was trying to continue to work on that and I'm going to try to use that same approach when I'm up here, and hopefully I can help the team any way I can."
While he gained confidence with consistent playing time, Krauss also worked on his mechanics, getting his front foot down early to be ready for the fastball.
"I'm trying to focus on staying back more and putting more of an effort into that," he said. "It's more of that approach and stuff and trying to be aggressive from the first pitch."
