Zach Eflin throws his fastball more than 60 percent of the time. Last season, he threw his curveball just 4 percent of the time. In his season debut against the New York Mets on Tuesday, Eflin snapped off 15 curveballs, easily his second-most-used pitch.
Instead of dishing them out, Eflin has dealt with his own curveballs in his short stint as a major leaguer.
The 23-year-old made his debut last season on June 14 in Toronto. It had to be a dream come true for the young pitcher, but it quickly turned into a nightmare.
