Alec Marsh has shown an improved fastball since coming off the IL:
In his first five starts of the season, Marsh threw 131 four-seam fastballs — throwing the four-seamer 31.7% of the time — and got 15 whiffs on it.
In the two games since returning from the IL, Marsh has gone to the four-seamer 43% of the time. He has generated 19 whiffs on the heater in those two starts, with a career-high 10 last Friday against the Angels and nine more Wednesday.
“Just good locations on it,” Marsh said.
