Griffin Jax allowed three runs (two earned) on four hits in four innings against the Red Sox on Thursday.
Jax struck out three and walked one while throwing 59 pitches in this one. The former reliever showed off a six-pitch mix in this one, using five pitches at least 14 percent of the time. He threw plenty of strikes with his sinker and four-seamer and was able to use his changeup for whiffs against both righties and lefties. However, no other pitches really missed many bats, and he had just a 10 percent swinging strike rate. We’ll need to see a little more strikeout upside from Jax if he’s going to be relied on in fantasy leagues. He should be able to push to five innings next week against the Blue Jays, but we’d hold off on starting him for now.
