Answer
Roger Clemens holds the record for most wins at Fenway Park with 216. He is also the all-time leader in strikeouts with 3,544 and shutouts with 59. Clemens pitched for the Red Sox from 1984 to 1996, and then again from 2007 to 2008. He is one of the greatest pitchers of all time, and his record at Fenway Park is a testament to his greatness.
