The Mariners have announced that they’ve designated infielder/outfielder Richie Shaffer for assignment. The move clears roster space for incoming starting pitcher Chris Heston, who was acquired in a trade with the Giants that is now official.
The Mariners acquired Shaffer (along with Taylor Motter) in a small deal with the Rays last month. The 25-year-old Shaffer was the 25th overall pick in the draft in 2012. He’s spent parts of the past two seasons in the big leagues, batting .213/.310/.410 in 142 plate appearances. He was unimpressive in a larger sample this year at Triple-A Durham, batting .227/.329/.367 in 496 trips to the plate. He had a strong year on the farm in 2015, swatting 26 homers, and he’s capable of playing first base, third base or right field, so it’s not impossible a team could take a chance on him as a waiver claim.
