Rays activate Hanigan, option Casali

BALTIMORE -- The Rays activated catcher Ryan Hanigan (left oblique strain) from the 15-day disabled list on Tuesday and optioned catcher Curt Casali to Class A Advanced Charlotte.

"It's great to be back," Hanigan said. "It's been a long, frustrating deal here. But I feel good. Body feels strong and rested and healthy now. The oblique's doing much better now. No pain."

Hanigan, who was placed on the DL on July 17 retroactive to July 9, has missed the last 38 games due to injury. He was shut down after his first rehab game with Charlotte on Aug. 2, but played three more games with the Stone Crabs over the weekend, going 3-for-10 at the plate.

"I didn't get a ton of at-bats," Hanigan said. "... But from my perspective, I've been out too long and I can help the team defensively as well. My bat didn't feel terrible. It might be a little bit of an adjustment period. Hopefully not."

Hanigan is hitting .212 with four home runs and 27 RBIs on the season, but he is hitless in his last 15 at-bats with the Rays. Entering Tuesday night's action, he had played in 113 consecutive errorless games at catcher, the longest streak of his career. His last error came on May 19, 2013, at Philadelphia.

Casali played in 23 games and hit .169 with two RBIs in 59 at-bats. But he managed to make an impression on Rays manager Joe Maddon.

"I just thought he played a pretty complete game," Maddon said. "And the thing I liked about him, if you gave him a game plan he could really carry it out. He was really bright. From a lot of different levels we liked having him here and he did well by us."

Casali will spend the rest of the week at Charlotte before returning as a September callup on Sept. 1.

Longo rests sore forearm as DH

BALTIMORE -- Evan Longoria served as the designated hitter for a second consecutive day Tuesday night because his right forearm has been "a little sore."

"I don't think it's any cause for concern," Longoria said. "It's something I've been playing through five days before that. And just kind of trying to give it a rest and a chance to calm it down. It doesn't bother me when I hit. That's a good thing. Should be back in there [at third base] tomorrow."

Longoria, who went 2-for-4 with a double and two RBIs in Tuesday's 4-2 loss, said he did not begin to feel pain on one particular play.

"It just kind of crept up on me," Longoria said. "Pretty sore throwing the ball. Something I won't go on the DL for, won't miss any time for.

"I didn't feel anything and I conveyed that to [the Rays]. Just, I came in one day and I just felt like I did too many forearm exercises. It kind of just stayed there. I was hoping if I backed down my throwing a little bit and just threw during the game that it would go away. But it stayed there. So we kind of look for those days to have DH days. And thankfully these are two days that actually work out for me to DH and still get the guys in the lineup that we need to get in there."

Longoria has not had an MRI and does not anticipate having one.

"Just keep treating it," Longoria said. "I really don't see it being a problem. ... But I've always wanted to play the field. I probably could have played today if it was necessary. But in talking to the trainers and talking to Joe, if we have the opportunity to DH me one more day to get it calmed down, I think it's the best case."
