Houston first baseman Chris Carter is expected to be a mainstay in the middle of the Astros lineup this season, reports MLB.com. "[Carter] will be a run producer in our lineup, one way or another," Astros general manager Jeff Luhnow said. "And a guy that we really needed, who we didn't really have last year -- a dangerous part of our lineup. We had some good hitters at times, but you never would face two or three guys that would really potentially scare you."
