Pedro Beato (shoulder) was diagnosed with rotator cuff inflammation.

Beato was pulled from Tuesday's game due to right shoulder tightness. An MRI ruled out any structural damage and he's scheduled to begin some light throwing on Friday. The 25-year-old right-hander posted a 4.30 ERA and 39/27 K/BB ratio in 67 innings last year as a rookie and now appears likely to open the 2012 season in the minors.

Pedro Beato (shoulder) is scheduled to undergo an MRI in Florida on Wednesday afternoon.

Beato was pulled from Tuesday's game due to right shoulder tightness. The Mets don't believe it's anything serious, but we'll soon know if he has to miss significant time.

Pedro Beato has been diagnosed with shoulder tightness.

Beato felt a bit of discomfort after throwing a warmup pitch during Tuesday afternoon's Grapefruit League game against the Cardinals. The Mets will give the 25-year-old right-hander a couple days of rest.

Pedro Beato was pulled from Tuesday's Grapefruit League game due to an apparent shoulder injury.

Beato was spotted pointing to his upper right arm after an ugly warmup pitch. The Mets are likely to have him checked out by team trainers and should provide an update on his status before the end of the day Tuesday.

Mets manager Terry Collins said following Tuesday's game that Pedro Beato is going through a "little bit of a dead arm" period.

Beato didn't pitch Tuesday night because Collins is trying to give him two or three days off to recuperate. The Rule 5 pick has a 4.29 ERA and 37/27 K/BB ratio over 65 innings this season.

Mets manager Terry Collins indicated that Pedro Beato would get the ball in a potential save situation Thursday against the Cardinals.

It makes sense, as Jason Isringhausen and Bobby Parnell have both pitched on back-to-back days. Izzy threw 34 pitches over two innings of scoreless relief in Wednesday's extra-inning win.

Mets activated RHP Pedro Beato from the 15-day disabled list.

Beato spent a little over two weeks rehabbing his sore right elbow. He has not allowed a run and has fanned 10 batters in 17 big league innings this season.

Pedro Beato (elbow) allowed two hits and a walk in 1 1/3 innings during a rehab appearance Sunday for Triple-A Buffalo.

Beato is expected to pitch Tuesday before being activated from the disabled list. The Rule 5 pick has not allowed a run in his first 17 innings with the Metropolitans.

Pedro Beato (elbow) is expected to be activated from the disabled list following rehab appearances at Triple-A Buffalo Sunday and Tuesday.

It looks like Beato will beat Bobby Parnell back to the Mets bullpen. The Rule 5 pick has been awfully impressive, not allowing a run in his first 17 innings with the Metropolitans.

Mets placed RHP Pedro Beato on the 15-day disabled list, retroactive to May 2, with right elbow tendinitis.

Beato, a Rule 5 pick from the Orioles, has quickly emerged as one of the go-to guys in Terry Collins' bullpen, so this is a tough blow. The 24-year-old right-hander has not allowed an unearned run over his first 17 innings of work. There's no clear timetable for his return.

Pedro Beato hasn't allowed an earned run while posting a 9/3 K/BB ratio over his first 11 innings this season.

"I've been impressed every since he walked into camp," Mets manager Terry Collins said of the Rule 5 pick. "He's handled everything. He's not intimidated. He's handled the rookie stuff tremendously. His delivery is more sound. I think you see the results of it all." Beato earned his first hold of the season Saturday and could start working his way into more pressurized situations.

SI.com's Jon Heyman reports that Mets' Rule 5 pick Pedro Beato will make the Opening Day roster.

No surprise here. Beato has impressed the Mets with his fastball velocity this spring and has been a shoo-in for a roster spot for a while now. The final spot in the bullpen will come down to Blaine Boyer, Jason Isringhausen and Manny Acosta. Izzy should have the leg up if he shows his elbow is OK, but Boyer has also been impressive in camp.

Rule 5 pick Pedro Beato pitched a pair of hitless innings Friday against the Marlins.

Beato lowered his spring ERA to 3.09, though his 5/4 K/BB ratio in 11 2/3 innings isn't so impressive. Still, he's pretty much nailed down a spot in the Mets' bullpen. That could mean Manny Acosta will be traded at some point over the next few days.

Buster Olney of ESPN.com hears that the Mets intend to keep Rule 5 picks Pedro Beato and Brad Emaus.

Emaus has been considered the front-runner for the second base job for a while now, but Beato is an interesting case. While the 24-year-old right-hander hasn't pitched above Double-A, his low-to-mid 90s heat is drawing raves from scouts this spring. Beato has a 3.72 ERA and 4/3 K/BB ratio over 9 2/3 innings during exhibition action.

David Lennon of Newsday believes that Rule 5 draft pick Pedro Beato is "pretty much a lock" to make the Mets.

Beato was the No. 32 pick in the 2006 draft, but his stock dropped since then and he was converted to relief. He was plucked from the Orioles in the second round of the Rule 5 Draft. The 24-year-old right-hander posted a 2.11 ERA and 50/19 K/BB ratio over 59 2/3 innings with Double-A Bowie last season. He could mop up innings as the last man in the Mets bullpen this season.

Mets selected RHP Pedro Beato from the Orioles in the second round of the Rule 5 Draft.

The Mets originally drafted Beato in 2005, but after he was left unsigned, the Orioles picked him up as the No. 32 pick in the 2006 draft. Beato's stock has dropped since then and he is now a relief pitcher. The 24-year-old right-hander posted a 2.11 ERA and 50/19 K/BB ratio over 59 2/3 innings with Double-A Bowie this past season and has a chance to make the Mets roster out of the bullpen.
