Hellickson (right shoulder inflammation) was activated from the 15-day disabled list after missing his last two starts. Farnsworth, who has been sidelined the entire season with a right elbow strain, was activated from the 60-day disabled list. And Peralta returned from his eight-game suspension due to his use of a foreign substance on his glove.
To make room on the roster for Hellickson and Farnsworth, the Rays optioned Cesar Ramos and Brandon Gomes to Triple-A Durham after Friday night's 4-2 win over the Tigers.
Rays manager Joe Maddon said that having all three pitchers back "makes us thicker earlier in the game."
"Because also J.P. [Howell has] been better and you've got [Burke] Badenhop to contend with also," Maddon said. "And then Wade [Davis]. There are a lot of good names in there who have really pitched well. It just permits us to shorten games up.
"And if you were to get hot, which hopefully we would, you don't wear anybody out while you're going through this moment. Because the concern is always that when you get going pretty well, you are going to wear people out by using them too much. But now I think we're at a point with enough candidates that it should prevent us from wearing anybody out."
During Peralta's suspension -- when the Rays had to use a 24-man roster -- the team went 3-5. Nevertheless, Maddon felt like the team hung tough despite the hardship.
"I thought so," Maddon said. "There might have been another victory or two out there for us if we had everybody there. But that's the way it works sometimes. And we're just grateful to have him back and still be in pretty good shape."
Peralta just seemed happy to have the ordeal behind him.
"It's been way too long," Peralta said. "This eight days has been the longest eight days in my baseball career. It felt like I've been out for a month. Watching these guys play every day -- it's not fun."
Farnsworth offered praise to the Rays' training staff.
"I gotta give a lot of credit to the training staff," Farnsworth said. "They were great to just get me back to this situation. It's been a long three months. We knew we had to take our time on it."
Like Peralta, Farnsworth seemed pleased to be back with the team and game ready.
"It's always good to be back," Farnsworth said. "This is what I love to do. It's never fun to have to sit back and not do the things we love to do. It's kinda like the first day of school, I'm excited.
"I'm just gonna go out there and do the best I can. I'm not gonna try and go out there and do anything different or anything more."
