One unfortunate pitch cost him the game. But what we saw is about what we can expect - how the Red Sox offense performs in his games is going to make the difference. After yesterday's game he has a 4.50 ERA with the Red Sox. He pitched from 2009 through 2014 for the Tigers, with a 76-63 (4.30 ERA) record, three years in a row pitching in the postseason (2011-13), with a similar 4.41 ERA and a record of 0-2.
It's of some note that he now joins the list of Red Sox players who also had relatives who played for the Sox. Sam Dente (1947) was his grandfather.
