PHILADELPHIA -- Phillies right-hander Vance Worley confirmed Thursday what many had been anticipating: He will make a spot start Saturday against the Mariners.
Worley was in Philadelphia on Thursday afternoon as the Phils wrapped up their 11-game homestand against the Marlins.
To open a roster spot for Worley, lefty reliever J.C. Romero was designated for assignment.
Beyond Saturday's start, however, it's unknown whether the Philadelphia will keep Worley in the rotation or continue with Kyle Kendrick.
"I know I'm throwing Saturday," Worley said. "I don't know if it's for one game and then I'm out of here or if I'll be up here. I really don't know anything. I know [Kendrick's] throwing well, and I'm happy for him he's throwing well."
Worley was sent down to Triple-A Lehigh Valley following his May 29 start against the Mets because he wasn't working consistently.
He made three starts for the IronPigs, going 2-0 and allowing three earned runs and 12 hits with 21 strikeouts.
Getting stretched out, refining his offspeed pitches and building his velocity in Allentown was a better fit than trying to sort all that out in Philadelphia, he said.
"It was better for me to do it down there than up here," he said. "I think I would've been more stressed out if I would've had a rough outing like that again."
Kendrick is coming off a strong seven-inning showing Wednesday, in which he allowed just one run in an 8-1 win against the Marlins.
It's unclear what direction the Phils will go in after Saturday. They can option Worley and continue with Kendrick or keep Worley in the rotation and put Kendrick in the bullpen and fill a need for long relief.
