Daniel Espino struck out two in a perfect inning against the Brewers on Wednesday in his major-league debut.

Espino was one of the top pitching prospects in baseball roughly a half-decade ago, but injuries, including two shoulder surgeries, derailed his trajectory and cost him nearly four full seasons in the minors. The 25-year-old deserves plenty of credit for persevering and completing his journey to the big leagues, though he’s unlikely to offer much immediate fantasy appeal in a low-leverage relief role. The long-term durability questions linger, but the off-the-charts raw stuff is still there, giving him a chance to eventually grow into a high-leverage role down the line.
