The Astros haven't provided official word that Imai will pitch Wednesday, but he hasn't been used since Aug. 3 and didn't join the team's other relievers in the bullpen for Tuesday's 4-1 loss, which seemingly signaled that he was being saved for the series finale. Since being dropped from the rotation in late July, Imai has made two relief appearances and was sharp in his most recent outing, striking out five over three perfect innings. King will likely cover the first inning or two before giving way to Imai, who should be capable of providing a decent amount of length since he had only recently been removed from a starting role.

Imai was stellar in his first appearance out of the bullpen for the Astros, as he held Toronto without a baserunner for three innings while striking out the final five batters he faced. It's certainly an encouraging development for Imai, who struggled to a 7.71 ERA across 11.2 innings in his last four starts. In the wake of Monday's successful performance, Houston figures to keep Imai in a bulk-relief role for the time being. Overall, the right-hander carries a 6-4 record with a 5.55 ERA, 1.46 WHIP and 77:40 K:BB across 61.2 innings this season.
