After missing his first game of the season in the Mariners' 3-2 loss to the Yankees last night, first baseman Justin Smoak has been placed on the 15-day disabled list with a strained left quad.

After hitting .250 with 15 RBIs in Seattle's first 25 games, Smoak has cooled off by hitting just .180 over the team's last 38 games.

Replacing Smoak in the lineup for tonight's game against New York is utility player Logan Morrison. Morrison hasn't suited up for the M's since April 14 when a strained right hamstring forced him the the disabled list. Playing in just nine games so far this season, Morrison has hit just .150 without any home runs or RBIs.

The Mariners, who have won eight out of their last 10 games, could use a little more help on offense. Seattle is tied for eleventh in the A.L. with 49 home runs and tenth in the A.L. averaging 4.12 runs per game.
