What happened: Serna reached safely on a 97.3 mph four-seam fastball in his first MLB start. The single came one day after his Sept. 1 debut and followed his first career RBI earlier in the game.
Why it matters: The milestone gives Jared Serna a tangible result two days after his Aug. 31 call-up. His promotion from Triple-A puts him in position to compete for September playing time.
By the numbers: Serna's single had a 98.2 mph exit velocity, a minus-8-degree launch angle and a 16-foot distance. Through two games, he was 1-for-3 with one RBI and one walk, producing a .333/.400/.333 slash line.
What to watch: The next lineup will show whether Serna receives a second consecutive start.
