Harrison uses a sinker, a four-seamer, a good change, and a curve and occasional cutter. He’s faced mostly righties in his Texas career, as he’s got fairly standard platoon splits – this is part of the reason why he hasn’t thrown as many cutter/curves. The M’s can actually throw out quite a few right-handed bats right now, but they’re still not hitting lefties terribly well. Some of this may be due to the quality of the lefties they’ve faced, and some of it is just luck. In fact, the M’s biggest problem on offense has been their production against right-handed pitchers. Against lefties, the M’s haven’t been great, and they’ve not hit for power, but they clear the low bar of a .300 OBP. Against righties, the M’s *have* hit for power, but that’s about the only semi-positive thing you can say about them.
