Astros first baseman Jon Singleton is ready to put the 2014 season in his rear view mirror. Singleton hit a woeful .168 with 13 home runs and 44 RBI in 310 plate appearances in 2014.

"To be honest, I believe the only competition I have is myself," Singleton said. "I feel like I'm the only person who can prevent myself from reaching the potential I need to reach or getting out of the game what I need to get out, but if I prepare and I work and I leave it all out there, there's nothing really else to worry about."

Manager A.J. Hinch thinks Singleton is a threat to hit 30 home runs this year.

"He's done what he needs to do this offseason to come in and improve off of, not only a tremendous Minor League career, but his start to the Major League career last year, which was mixed," general manager Jeff Luhnow said. "My money's on Jon Singleton to do the things he needs to do to make this club."
