The Giants announced they’ve acquired outfielder AJ Pollock, utility player Mark Mathias and cash considerations from the Mariners. Seattle receives a player to be named later or cash in return. San Francisco optioned Mathias to Triple-A, placed Mike Yastrzemski on the 10-day injured list, and transferred right-hander John Brebbia to the 60-day injured list in corresponding moves.
Jon Morosi of MLB.com tweeted this afternoon that San Francisco was among the teams looking for right-handed hitting. They add a pair of righty bats in this trade, although neither is necessarily a surefire offensive upgrade.
Mathias, whom the Mariners acquired off waivers from the Pirates earlier this month, departs the organization without ever joining the big league roster. The 28 year old offers experience all around the diamond, though he has primarily played second and third base throughout his career. Initially drafted by Cleveland in the third round of the 2015 draft, Mathias has bounced around the league since making his big league debut with Milwaukee in 2020, with stints in Pittsburgh and Texas over the past calendar year.
In 68 career games at the big league level, Mathias’s .249/.323/.402 slash line is good for a slightly above average wRC+ of 104, though that overall line is primarily carried by an excellent 24-game stretch with the Rangers where he slashed a whopping .277/.365/.554 in 74 trips to the plate. While the journeyman has yet to stick in the big leagues for a significant period of time, that hot stretch in Texas and a career slash line of .289/.383/.458 at the Triple-A level indicate Mathias has the potential to be a useful big league utility piece.
The veteran Pollock, 35, has struggled considerably to this point in the season, slashing a brutal .173/.225/.323 in 138 plate appearances. He’ll provide the Giants with outfield depth as they look to weather injuries to Mitch Haniger and Yastrzemski, the latter of whom is expected to miss a couple weeks with a left hamstring strain.
Pollock had mashed left-handed pitching as recently as a season ago. He provides an outfield rotation option and experienced clubhouse presence alongside the presumptive starting group of Michael Conforto, Luis Matos, and Austin Slater, at least while Yastrzemski gets healthy.
The Mariners continue to move some short-term players following this afternoon’s trade of closer Paul Sewald to Arizona. The player to be named headed back to Seattle figures to be a relatively minor piece. Of greater import is that San Francisco might be taking on some of Pollock’s $7MM salary. The precise amount of the cash being sent from Seattle to the Giants remains unreported. Pollock is owed around $2.33MM through season’s end, at which point he’ll be a free agent.
Jeff Passan of ESPN first reported the Giants were finalizing a deal for Pollock and Mathias. Daniel Kramer of MLB.com reported the M’s could receive a player to be named later.
