The Red Sox sent Ingrassia to the Tigers on Saturday to complete the Jahmai Jones trade, Robert Murray of FanSided.com reports.
Ingrassia has spent the entire season with Boston's High-A affiliate, posting a 3.27 ERA and 1.18 WHIP over 44 innings. He'll likely remain at High-A to begin his tenure with the Tigers, but the 24-year-old southpaw could reach Double-A Erie by the end of the year.
