The Blue Jays called up right-hander Liam Hendriks to start their series opener Friday night against the Cincinnati Reds, part of a rotation rearrangement.
R.A. Dickey was scheduled to start, but was pushed back until Sunday, giving him a couple of extra days to let a sore groin heal. Hendriks went 1-0 in two starts with a 2.31 ERA earlier this season.
Right-hander Steve Delabar was optioned to Triple-A Buffalo. He was sent down on Tuesday and called back on Thursday when Brett Cecil went on the DL. Delabar walked three in the seventh inning of a 6-4 loss at Yankee Stadium on Thursday.
Delabar was 3-0 with a 4.91 ERA in 30 relief appearances, walking 19 in 25 2-3 innings.
