The Mariners have announced that the club designated outfielder Dan Robertson for assignment to clear space for the signing of Hisashi Iwakuma. And the team further announced that previously-designated lefty Tyler Olson has been dealt to the Dodgers for a player to be named later or cash.
The 30-year-old Robertson spent the 2015 season with the Angels, where former Anaheim GM and current Seattle GM Jerry Dipoto had acquired him from the Rangers. He logged 80 plate appearances with the Halos, upping his big league total to 277. In that time, Robertson is a .274/.324/.325 hitter. He also boasts a solid minor league track record and is capable of playing all three outfield positions, making him a valuable depth option for a big league team.
Olson, 26, made his big league debut with the Mariners last season, pitching 13 1/3 innings out of the bullpen. The results weren’t particularly encouraging, as he surrendered eight runs on 18 hits and 10 walks, although in one of the more bizarre stats you’ll come across, seven of those 10 walks were intentional in nature. In 54 1/3 Triple-A innings, Olson managed a more palatable 4.47 ERA with 8.8 K/9 against 2.8 BB/9. However, after holding lefties to a .206/.280/.279 batting line in 2014, the Gonzaga product yielded a .253/.340/.448 slash to lefties between the Majors and minors in 2015.
