Should we be worried about the Athletics flamethrower throwing a high-80s fastball right now?
Despite only once recording a fastball at 90 miles per hour, left-handed relief pitcher Sean Doolittle recorded a scoreless sixth inning for the Athletics. He struck out two batters and allowed one hit in his inning of work.
Gameday recorded Doolittle throwing two curveballs, three changeups, and nine fastballs in his 14 pitches of work, with Castellanos striking out on an 80 mile per hour changeup. Doolittle's fastball was most frequently recorded at 89 miles per hour.
As Doolittle told me the other day, this is part of a process - he's still getting better.
