Lodolo was promoted from Double-A Chattanooga to Triple-A Louisville on Tuesday, Mark Sheldon of MLB.com reports.
Lodolo is one of the best pitching prospects in the minors. He logged a 1.84 ERA, 0.91 WHIP and 68 strikeouts in 44 innings (10 starts) at Double-A. It's possible he could make his big-league debut if the Reds need reinforcements later this summer.
