MIAMI -- The Devil Rays optioned Chad Orvella and Tim Corcoran to Triple-A Durham on Sunday night.

Both pitchers played roles in the Rays' bullpen blowing big leads to lose games during the past week. On Tuesday night, the Rays led the Blue Jays, 11-6, in the ninth inning before losing, 12-11, and they blew an 8-2 lead against the Marlins on Friday night in a 14-8 loss.

Orvella, 26, was recalled May 8 from Triple-A Durham and has pitched in 10 games since rejoining the club. He allowed runs in eight of 10 outings and in each of his last seven, including Friday night's loss to the Marlins in which he surrendered three runs on three hits and two walks in one inning.

Corcoran, 28, was recalled May 8 from Durham and has pithed in nine games and allowed runs in six of them. He has walked seven of his last eight batters, including four Friday night and three Tuesday in Toronto, including the walk-off run.

Corresponding moves will be made prior to Tuesday night's game against the Padres at Tropicana Field. Seth McClung, Ruddy Lugo, Jeff Ridgway, Steve Andrade and Scott Dohmann are all possibilities to get the call from Durham. Also on the radar is Double-A Montgomery's Dale Thayer, who is 4-0 with a 2.35 ERA and 14 saves in 15 opportunities.

Navarro better: Catcher Dioner Navarro reported feeling much better prior to Sunday's game than he has since getting hit in the throat with a ball during Friday night's game.

"I think everything is going to be fine," Navarro said.

Navarro went through drills with head trainer Ron Porterfield on Saturday, and everything went well.

"We did our stuff," Navarro said. "Now I feel good. I did my stuff yesterday running and I feel good. Hopefully I pinch-hit today and hit a bomb."

Navarro might have some added incentive given the fact backup Raul Casanova connected for a 416-foot home run Saturday night.

"Whenever somebody comes off the bench and plays in your spot, that's probably the most effective form of medicine there is," Rays manager Joe Maddon said. "Nobody wants to be 'Pipped.'"

Maddon referred to Wally Pipp, the Yankees first baseman who sat out of the lineup with a headache and got replaced by Lou Gehrig. Gehrig, of course, went on to play an entire career without sitting again.

Baldelli mending: Injured center fielder Rocco Baldelli played in an extended spring game Saturday.

"He did well yesterday at extended spring," Maddon said. "He scored twice from second base. Ran like 4.5 or 4.6 to first base, which is good. Keep it under control. Overall, it was a pretty good day for him; pretty encouraging."

There are four remaining extended spring games before the season is over.

Baldelli is "off today, and we'll see what he looks like tomorrow," Maddon said. "Four games this week, it would be nice to get him involved in all of those. ... We just keep progressing this way, it looks good."

Maddon speculated that by the end of the week Baldelli would either be activated or sent out on a rehab assignement.

Baldelli is out with a left hamstring strain. Since the injury is his second hamstring injury this year, after having an earlier problem with his right hamstring, the Rays want to re-examine Baldell's approach for keeping his legs in working order.

"Basically, a lot of it's based on his running technique and the kind of work he does off the field," Maddon said. "The workout side of it, the non-baseball side of it. Things he can do with [the team's trainers], and the training room. Those are the things we're finding out are more increasingly important. ... It's going to require a lot of work on his part, off the field, to keep him well."

Upton up in air: B.J. Upton remained out of the lineup Sunday after suffering a strained left quadriceps Friday night.

The Rays continue to monitor his progress.

"By Tuesday, we should have a pretty good idea," Maddon said. "He'll play Tuesday, obviously, if he can. I've got an idea it will be Wednesday or Thursday after that. But Ronnie [Porterfield] doesn't see an extended thing with this. It's just as he becomes less sore and is more able to do things. Tuesday will be a good idea to find out what we've got."

Up next: The Rays begin a three-game Interleague series against the Padres on Tuesday night in a 7:10 p.m. ET contest at Tropicana Field. Left-hander Scott Kazmir will pitch for the Rays and will be opposed by right-hander Greg Maddux.
