Lefty Eduardo Rodriguez is on the mound for the Red Sox, and he's delivered excellent peripherals in his nine starts, in which Boston is 6-3 despite only two of them coming at home. The Mariners are 29th in the majors in OPS vs. lefties. The Red Sox have won four in a row, all by big margins, and now they'll face Yovani Gallardo, who's in the middle of bad season and coming off an atrocious start. Boston's a great bet to win at home today, and I'd consider parlaying them with another big home fave for some easy money.
