Littell was promoted to Double-A Trenton on Wednesday. He logged seven scoreless frames, allowing two hits and three walks while striking out 10 in his first start for the Thunder.
Littell has been great this season, showing the Yankees his potential with every outing. He came into the year projecting as a potential No. 4 or No. 5 starter, but that might need to be revisited, given his success. Thursday's strikeouts look like a major outlier, but his ability to prevent runs in the minors is hard to argue with at this point.
