The Mariners have acquired a number of players that could compete for time at first base and designated hitter, which means this will be a big spring for Justin Smoak.

Seattle added Kendrys Morales, Mike Morse and Raul Ibanez this offseason.

"I'm excited," Smoak said. "We've got some guys who can hit, and that's what you want. For me, personally, I know if I just play like I should play, I've got nothing to worry about. I know for a fact, this is most confidence I've ever felt going into a season."

Smoak, 26, hit just .217 with 19 home runs and 51 RBIs in 132 games last year.
