In December 2007, Epstein was mentioned in the Mitchell Report regarding a November 2006 email exchange he had had with Red Sox scout Marc DelPiano on the possible acquisition of closer Éric Gagné. In the email, Epstein asked DelPiano, "Have you done any digging on Gagné? I know the Dodgers think he was a steroid guy. Maybe so. What do you hear on his medical?" DelPiano replied that "steroids IS the issue" with Gagné, questioned his "poise and commitment" and expressed questions about his durability "without steroid help." Despite DelPiano's reservations about Gagné, Epstein traded Kason Gabbard and minor league outfielders David Murphy and Engel Beltré to the Texas Rangers for Gagné on July 31, 2007. The Red Sox went on to win the 2007 World Series, Epstein's second championship with Boston.
