NEW YORK -- Needing to sacrifice a bench player in exchange for pitching help, the Mets placed Fernando Tatis on the disabled list Monday with a right shoulder AC joint sprain, recalling left-hander Raul Valdes from Triple-A Buffalo to replace him.
Tatis will undergo further testing on Tuesday at New York's Hospital for Special Surgery.
"He's had some problems with it since even Spring Training," manager Jerry Manuel said. "That has a lot to do with the fact that he wasn't able to get the bat in a position of strength with that shoulder. I guess the doctor looked at it today and decided that's the best thing for him."
Tatis, 35, was batting .185 almost exclusively as a pinch-hitter. He had recorded only two hits since May 23, one of them a bloop double.
Valdes, 32, posted a 5.10 ERA in 30 innings earlier this season -- somewhat of a disappointment after he fashioned a 1.86 ERA in April.
The Mets, primarily, are interested in his fresh left arm. After using five relievers in Sunday's 9-5 victory over the Nationals, two on Saturday and four on Friday, the team desperately needed a pitcher capable of throwing multiple innings. Valdes, who pitched at least three innings in four of his 20 appearances with the Mets, fits that bill.
"We needed someone that could give us some length," Manuel said. "He's a guy that's been here and has done a decent job."
The Mets made one other move to shore up their bullpen, altering their rotation to bump Hisanori Takahashi from his final start of the first half. In place of Takahashi, Mike Pelfrey will start on regular rest on Saturday. Johan Santana will start Sunday.
Takahashi, who threw 86 pitches in Sunday's game, will be available out of the bullpen starting Wednesday.

Reyes willing to do 'right' thing to return
NEW YORK -- Switch-hitter Jose Reyes is ready to bat right-handed against right-handed pitchers if that's what he needs to do to return. And his manager, Jerry Manuel, has signed off on the idea.
Reyes, who has been sidelined since Wednesday with a right oblique strain, no longer feels limited batting from the right side. It is swinging left-handed that gives him trouble.
With that in mind, Reyes was originally scheduled to make his return to the starting lineup Tuesday against Reds left-hander Travis Wood. But the Reds scratched Monday's starter, Aaron Harang, roughly a half-hour before first pitch, moving Wood into his slot.
Most likely, the Reds will start Harang on Tuesday, leaving the Mets with two choices: allow Reyes to hit right-handed, or keep him confined to the bench. They are leaning toward the former.
"If Jose is ready to play, and I think he wants to play -- I know he wants to play -- then he will probably bat right-handed," Manuel said.
"I want to play," Reyes said. "It doesn't matter if it's right on right. I want to play. When the left side feels good, I can bat from the left side. But right now, the right side feels very good."
Reyes, a reserve on the National League All-Star team, remained unsure if his injury would affect him next week in Anaheim.
"I'm going to go for sure," Reyes said. "I don't know if I'm going to play, but I'm going to go."
Beltran feeling 'better and better every day'
NEW YORK -- Finally, with the rains gone from Port St. Lucie, Fla., Carlos Beltran was able to play a full nine innings in center field for the first time in July.
"I feel better and better every day," Beltran said after going 2-for-4 with two singles and an RBI for Class A St. Lucie.
Beltran had intended to play back-to-back nine-inning games in center field this weekend, but rain and lighting issues prevented him from doing so even once. He still intends to accomplish the feat before leaving Port St. Lucie, Fla., though he did play nine innings Monday after lasting 7 2/3 the day before.
Last weekend, the Mets put a hard timeline on Beltran's return, saying they expect him back for the first game after the All-Star break in San Francisco.
"That's like adding a player before the [Trade] Deadline," manager Jerry Manuel said. "You're talking about a real good five-tool player. So I think for us it can be a very positive impact -- a switch-hitter that sits in the middle of the lineup. I anticipate it to be positive."

Thole making impression on Mets skipper
NEW YORK -- Jerry Manuel has taken a liking to his young catcher, Josh Thole. And Thole has benefited from it.
Though the left-handed Thole was a late scratch from Monday's lineup after the Reds scratched right-handed pitcher Aaron Harang, Manuel noted before the game that Thole would continue to receive regular starts behind the plate as long as he remains on the club.
And that could be for some time. Though Thole was at risk of a demotion Monday, with the Mets needing to recall a reliever, the team placed Fernando Tatis on the disabled list instead.
That should allow Thole to continue playing at least through the All-Star break -- starting semi-regularly against right-handed pitchers and perhaps catching knuckleballer R.A. Dickey.
"I'd like to see what we have in Josh," Manuel said. "They really did a good job, because he's much-improved as far as receiving from what we saw here last year. I'm just kind of interested in what we have, because I know offensively he looks like he can really be a big help for us."
