Sale has held hitters to a .655 OPS with men on base and a .669 with RISP. Also a .646 OPSA in Late and Close situations.
In High Leverage situations, his OPSA is .794 in 42 PA. Most of this is carried by singles, as he has only allowed 1 HR in these at bats and has an 18/2 K/BB ratio. (Although he has 3 hit batsmen).
In his 12 starts, he has faced the Yankees, Astros and Rays 5 times! (Sox are 1-4 in those games.) He was also victimized by very poor run support in some of his favorable match ups, such as being on the wrong end of an Aaron Brooks 1-0 shutout. Yes, Aaron Brooks.
