John Shea of the San Francisco Chronicle reports that Mike Leake is set to rejoin the Giants’ rotation on Saturday, in Pittsburgh against the Pirates. Shea adds that Leake will be taking Chris Heston’s spot in the rotation, and Heston will head to Triple-A Sacramento for a breather.
Leake, 27, was expected to return from the disabled list on Tuesday, but his left hamstring injury didn’t heal up as quickly as anticipated. Leake said on Thursday that his hamstring still isn’t one hundred percent and might not be for the rest of the season. The right-hander has made just one start since the Giants acquired him from the Reds, holding the Rangers to two runs in 6 1/3 innings on August 2.
Heston hasn’t been able to complete the fifth inning in three of his last four starts. In his most recent start, he needed 104 pitches to record 14 outs against the Cardinals. Nevertheless, he has a productive 3.34 ERA with a 110/48 K/BB ratio in 145 2/3 innings.
