After facing southpaw Drew Pomeranz, who has been hot, and Chris Sale, the premier lefty in the American League, the Blue Jays now get righty Rick Porcello. That's a big dropoff.

Porcello has yielded a career-worst 31 homers already this season and is coming off a Friday start against the Orioles where he gave up 11 runs on nine hits in fewer than five innings, although it should be noted seven of those runs were unearned. Porcello has a 4.70 career ERA versus the Blue Jays in 18 outings, including 17 starts. The Blue Jays have hit the 13th most homers in the majors.

Boston is a highly-impressive 60-42 against righties. The Red Sox, however, are only 15-15 versus lefty starters. They were under .500 against southpaws until beating Toronto and Brett Anderson, 3-0, last night. The much traveled and injured Anderson, though, pitched well against the Red Sox holding them to one run on six hits with no walks in 5 2/3 innings.

Southpaw J.A. Happ is better than Anderson and he goes against the Red Sox today. Happ went 20-4 with a 3.18 ERA last year. Happ isn't having that kind of season this year, but he's been solid holding eight of his last 12 opponents to two earned runs or fewer. He has a 3.66 career ERA in 13 starts against Boston.

The Red Sox remain without two key players, second baseman Dustin Pedroia and center fielder Jackie Bradley Jr.
