Robertson, 30, totaled 80 plate appearances with the Halos last season and has logged 277 trips to the plate in parts of two big league seasons split between the Rangers and Angels. He’s a .274/.324/.325 hitters as a Major Leaguer and is capable of playing all three outfield spots. Robertson has a nice track record in the minor leagues as well, where he has authored a .288/.364/.385 batting line in parts of four seasons at the Triple-A level.
Mariners general manager Jerry Dipoto is obviously quite familiar with Robertson, having acquired him from the Rangers while serving as general manager in Anaheim. This marks the second time that Dipoto has acquired Robertson, who fits the on-base percentage/athleticism mold which Dipoto has voiced a desire to add throughout the organization.
The 26-year-old Ramirez came to the Mariners from the Diamondbacks in a minor mid-season exchange, marking his second stint in Seattle. The Mariners were the team to initially sign Ramirez out of Nicaragua, but they traded him to Philadelphia along with Tyson Gillies and Phillippe Aumont in the now-lopsided Cliff Lee trade back in 2009. Ramirez has a 6.42 ERA in 47 2/3 Major League innings and a solid but unspectacular 3.80 ERA with 7.0 K/9 against 3.9 BB/9 in parts of four Triple-A seasons. He can refuse the outright assignment and elect minor league free agency.
