Giants Acquire A.J. Pollock, Mark Mathias From Mariners


On the eve of the trade deadline, the Giants swung a deal with the Mariners to improve their roster by nabbing outfielder A.J. Pollock and utility infielder Mark Mathias from Seattle.

Neither Pollock nor Mathias has been particularly productive in 2023, but each adds a little versatility to a San Francisco roster that has leaned heavily on rookies, including top prospects Luis Matos, Casey Schmitt and Marco Luciano.

In return the Mariners will receive a player to be named later. The move helpfully clears 40-man roster spots for Arizona.


Mark Mathias, INF
Age: 28
Mathias was selected by Cleveland in the third round of the 2015 draft out of Cal Poly. He made his big league debut with Milwaukee in 2020 and has made stops with Pittsburgh and Texas as well. He was claimed by Seattle off waivers from the Pirates on July 2 and had been playing with Triple-A Tacoma. He fits best as a bench player who can fill in at a number of positions. He has big league experience at every position except catcher and shortstop.

A.J. Pollock, OF
Age: 35
Pollock is a journeyman outfielder who has speed and has been dangerous against lefthanders throughout his career. He’ll add a bit of punch to a Giants team that has produced a .672 OPS against southpaws this season, second-worst in the big leagues in front of only the Twins. He is currently on the injured list with a left hamstring strain.
