The Phillies reliever has allowed six hits, six runs and two walks in just 1 1/3 innings in his last three appearances. He had a 0.00 ERA and five saves in five opportunities in his first 11 appearances this season, including his first four appearances following a stint on the disabled list because of an injured right elbow.
"I feel good," Contreras said.
But something has been amiss. In his last appearance Friday, his fastball hit 94 mph, but he lacked command of his splitter.
"I think I need a couple more games," he said. "The last game I felt good. It's been my command."
Contreras said his mechanics have been out of whack, but he said he has figured out his problem and hopes he finds more success the next time he pitches.
