Pryor said he'll be back with the Rainiers on Friday and is looking toward pitching in back-to-back performances sometime soon.
"I think it's coming in the near future, but I'm not sure what days," said the hard-throwing right-hander. "If I get through that and everything goes fine, that's kind of the test. But I've felt good. Mechanically, everything has been good. I'm just kind of working on pitches and trying to get back to where I was."
Pryor, 24, got hit hard in his first game back for Class A Everett, but has since allowed just one baserunner -- on a walk -- in three innings for Tacoma.
"The first outing was a little rough," he said. "But after that, things have gone pretty smooth. I just had to get the cobwebs out, I guess."
Pryor didn't allow a run in seven outings for the Mariners to start the year, allowing just three hits in 7 1/3 innings, but isn't quite back to that dominant level yet.
"I'd say I'm like in mid-Spring Training," he said. "It's fair to say it's a few outings away, hopefully. But I'm finally getting to play in some games, which is nice. It's a lot better than sitting in the training room."
