This is not the season to be backing the pitching-less Red Sox. Boston has lost 11 of the last 16 times it has been a home favorite.
At this price, I'm going to make a value play and take the Blue Jays, who have a better record than the Red Sox. 
Boston has a terrible bullpen and its starting pitching rotation has been decimated by injuries, trades and defections. Nathan Eovaldi, who gets the start here, could be the Red Sox's best starter. Eovaldi throws hard, but always has been inconsistent. He had a 7.71 ERA in two starts against Toronto last season. 
I believe Toronto's Matt Shoemaker can pitch well now that he has gotten the rust off. This will be his third start. He is 3-1 with a 3.00 ERA in four lifetime appearances versus the Red Sox, which includes three starts.
