Mariners outfielder/first baseman Mike Morse has been claimed off revocable trade waivers by the Orioles, according to Jon Heyman of CBSSports.com (via Twitter). Morse is the second notable player claimed by Baltimore in as many days – last night they had the winning claim on the Twins' Josh Willingham.

Morse, 31, has struggled this season, posting a .226/.283/.410 slash line with 13 homers in 307 plate appearances. It's a significant dropoff for Morse, who boasted a career .295/.347/.492 line heading into this sesaon.

The 70-61 Orioles are in need of an offensive upgrade as they look to make their playoff push. They're not likely to leapfrog the Red Sox and Rays for the AL East crown, but they are just 4.5 games back of the A's for the final Wild Card spot. In total, Baseball Prospectus' number crunch gives them an 8.8% chance of making the postseason.

Morse's teammate Kendrys Morales was claimed by an unknown club earlier this week but no deal was made within the allotted time, Heyman notes (via Twitter).
