Drew Pomeranz thanks Red Sox in heartfelt Instagram post originally appeared on nbcsportsboston.com When Drew Pomeranz signed with the San Francisco Giants earlier this offseason, Red Sox fans likely weren't all that upset to see the left-hander go. Pomeranz struggled mightily in 2018, posting a 2-6 record and 6.08 ERA in 26 appearances. A significant dropoff from his 2017 season, when the left-hander went 17-6 with a 3.32 ERA in 32 starts.
