The Giants have designated outfielder Aaron Altherr for assignment and activated left-hander Drew Pomeranz from the 10-day injured list, Maria Guardado of MLB.com was among those to report.
This is the second time this month that a team has booted Altherr from its 40-man roster. The Phillies did it previously when they designated Altherr on May 4, leading the Giants to claim him off waivers last weekend. Even though San Francisco’s outfield has been a mess this season, the club didn’t give Altherr much of an opportunity, allowing the 28-year-old just one at-bat before cutting him.
In fairness to the Giants, Altherr hasn’t exactly made a case for a big league roster spot over the past couple years. Altherr was a solid offensive producer in Philadelphia in 2017, when he hit .272/.340/.516 (121 wRC+) with 19 home runs in 412 plate appearances, but he has only batted .165/.272/.304 with eight long balls across 316 PA since then. Altherr’s 60 wRC+ is tied for eighth worst among hitters who have amassed at least 300 trips to the plate dating back to last season.
