SEATTLE -- The Mariners called up top prospect Jonatan Clase on Monday, looking to help spark an offense that has underperformed in the first 2 weeks of the season.

Clase, a 21-year-old switch-hitting outfielder, was batting .311 with 4 doubles, 2 triples and 2 homers in 12 games with Triple-A Tacoma. He spent last season split between Single-A Everett and Double-A Arkansas, and he appeared in 15 spring training games with the Mariners, who so far are batting .204 in the regular season and have an .590 OPS.

Clase, who is ranked as the No. 10 prospect in Seattle's organization, is batting eighth and playing left field in Monday night's game against the Cincinnati Reds.

He takes the roster spot of outfielder Dominic Canzone, who landed on the 10-day injured list with a sprained AC joint in his left shoulder suffered after crashing into the outfield wall while making a catch in Sunday's loss to the Chicago Cubs. There's no timeline on Canzone's recovery, but manager Scott Servais said after the game it would be a significant chunk of time missed.
