The Giants have sent Mark Mathias outright to Triple-A, according to his player page on MLB.com. Having been outrighted previously in his career, he is eligible to reject the assignment in favor of free agency, and at this point in the year, it’s hard to see why he wouldn’t do so. There was no previous announcement that Mathias had been designated for assignment or placed on outright waivers. He was on the 60-day injured list for the final six weeks of the season, so the move doesn’t free up a 40-man roster spot for San Francisco.
The 29-year-old spent the first three months of the year with the Pirates, bouncing back and forth between the majors and Triple-A. He was designated for assignment in late June and scooped up by the Mariners in early July, who stashed him at Triple-A for a month before trading him to the Giants at the deadline, along with AJ Pollock. Mathias played just five games for San Francisco, after which the utility player landed on the IL with a right shoulder strain. He would not play for the remainder of the season.
Overall, Mathias hit .226 with a .591 OPS in 27 games with the Pirates and Giants. In other words, he was unable to rediscover the success from his brief stint with the Rangers last season, when he hit five home runs in 24 games down the stretch, driving in 16 and posting an impressive 159 wRC+. Nevertheless, his strong performance at Triple-A for a second consecutive season (.813 OPS in 51 games) should earn him a minor league contract with a new club this winter, barring another setback with his shoulder.
