FOX Sports first reported Saturday that LaHair, 27, will compete for a spot on the Cubs' bench. The left-handed hitter has spent his entire career in the Seattle Mariners' organization. Last year at Triple-A Tacoma, he batted .289 with 26 homers, 28 doubles and 85 RBIs. He hit .313 and 21 of his total homers against right-handed pitchers.
In 2008, LaHair appeared in 45 games with the Mariners and batted .250 with three home runs and 10 RBIs.
The Cubs do have an overload of right-handed bats in the lineup and one of the matters to be resolved this spring is which left-handers will be on the bench. Micah Hoffpauir began the 2009 season on the Opening Day roster, but hit .239 in 105 games.
The Cubs are expected to announce their non-roster invitees later this month.
