SEATTLE -- After the Mariners beat the Indians, 3-0, on Sunday, they optioned rookie outfielder Stefen Romero to Triple-A Tacoma.
The move was made to clear room on the 25-man roster so the club can recall hard-throwing, right-hander Taijaun Walker, the organization's top pitching prospect. Walker has yet to be promoted from the Rainiers, but he'll make his 2014 Major League debut Monday night when the Mariners begin a three-game series against the Astros at Minute Maid Park.
Getting a start Sunday against Cleveland left-hander T.J. House, Romero, 25, went 0-for-3, which dropped his batting average to .196. The Oregon State product had just three home runs and 11 RBIs in his first 51 games with Seattle after using a strong Spring Training to make the team.
