On Monday, the Seattle Mariners sent outfielder AJ Pollock and utility player Mark Mathias to the San Francisco Giants in exchange for a player who will be named later.

Pollock is on the injured list with a strained hamstring. Before that, he had been struggling after signing a one-year, $7 million contract with Seattle as a free agent in the offseason. The 35-year-old joins his third National League West team after spending the first ten years of his career in Arizona and Los Angeles. He is hitting.173/.225/.323 with five home runs in 138 plate appearances and lost his starting job in mid-May.

Pollock is known for beating up on left-handed pitchers, but this season he has a.378 OPS against them and a.762 OPS against right-handers.

Farhan Zaidi, president of baseball operations for the Giants, said, “We were looking for guys who could help us right now because our position players are a little banged up. You’re always returning to your list of guys you’ve been interested in in the past or the offseason.” “He hasn’t had a great season in Seattle, but we look at how he moves around the field and how fast he sprints. We think he would be a great change of pace candidate.”

Mathias, who is 28 years old, joins his fourth team this season. In spring training, Texas traded him to Pittsburgh. Pittsburgh put him on waivers in early July, and Seattle picked him up. Mathias hit.299/.405/.427 in 47 Triple-A games between Pittsburgh and Seattle. He had four home runs and 20 RBIs.

The Giants have been seeking help in the infield and outfield through trades. However, the return of second baseman Thairo Estrada should help them since they already have the best wild-card spot in the NL.

Mike Yastrzemski, an outfielder, went on the injured list Monday after hurting his left hamstring again. He had already been on the IL twice this season because of the same problem.
