NEW YORK -- The Mets started the season with two Rule 5 picks on their 25-man roster. One, second baseman Brad Emaus, has been sold back to the Blue Jays and since traded to the Rockies. The other, reliever Pedro Beato, doesn't appear to be going anywhere anytime soon.
Beato, selected from the Orioles in December's Rule 5 Draft, has yet to allow an earned run this season. In 11 innings across eight appearances, the 24-year-old right-hander has struck out eight, walked two and surrendered three runs, all unearned. In Saturday's win over the D-backs, he earned his first Major League hold by pitching a perfect seventh inning.
"I've been impressed ever since he walked into camp," manager Terry Collins said before Sunday's series finale against Arizona. "He's just handled everything. He's not intimidated by anything. He's handled the rookie stuff tremendously. He and [pitching coach Dan Warthen] worked out a couple of things in Spring Training to help his delivery be more sound. He bought into it, and I think you see the results of it all."
"I think it's just the confidence the guys in the bullpen have given me," Beato said. "Just helping me out with the situations and guiding me through and having my routine and doing my job.
"Everybody in the bullpen has done a good job keeping me calm and keeping me on track."
As the least experienced pitcher in the Mets bullpen, Beato is charged with carrying out the pink backpack filled with snacks and other items essential to those who watch the game from beyond the right-field fence. That bag replaced a toolbox that the Mets destroyed in an effort to change their luck.
"Definitely the pink backpack," Beato said when asked which he preferred to carry. "It's gotten us three wins in a row."
Paulino may need more time on DL
NEW YORK -- An oblique injury appears increasingly likely to delay the return of Ronny Paulino, who is eligible to come off the disabled list on Tuesday in Washington when the Mets begin a six-game road trip.
Paulino, originally placed on the DL because of anemia, last played Friday, when he left a Triple-A game after five innings with tightness in his oblique. After Sunday's win over the D-backs, Mets general manager Sandy Alderson said Paulino will be reevaluated before Triple-A Buffalo's game on Monday. If that checkup goes well, Paulino will play.
"We will not re-activate him until we have seen him under game conditions," Alderson said. "His return is at least day to day. We're not expecting him to be ready for Tuesday. It's a possibility, but I'd say that's in jeopardy."
The Mets placed Paulino on the 15-day disabled list on April 10. Before that, the catcher had served the eight remaining games on a drug-related suspension from 2010.
The Mets signed Paulino to be a right-handed platoon partner for Josh Thole. Collins said Sunday the team would consider carrying three catchers when Paulino does return. Mike Nickeas is serving as the backup for now.
"When he comes back, will we benefit from having three catchers?" Collins said before Sunday's game. "Not just the fact that Ronny's bat off the bench, but maybe give us some flexibility of some pinch-runners, double-switch, always protect yourself."
Isringhausen to be handled carefully
NEW YORK -- After dealing with injuries during Spring Training, Jason Isringhausen has remained healthy since his callup to the Mets on April 11. Manager Terry Collins and the Mets want to keep their eighth-inning reliever that way.
"He told me he's fine, but I am probably going to go another route today," Collins said before Sunday's game against the D-backs. "He's really pitched good, and I want him to pitch good for a long time."
Isringhausen, who pitched an inning in each of the Mets' wins on Friday and Saturday, has logged 5 2/3 innings and allowed one run since his callup. Elbow and back pain had caused the Mets to ask him to remain in Port St. Lucie, Fla., until the season was a week and a half old.
"One of the things we asked him to do when he stayed in Florida was to show us he could pitch back-to-back days, which he's done," Collins said. "So I'm just going to be careful with him right now."
Collins said the restrictions would not last all season if Isringhausen, who has a lengthy injury history, proves he can stay healthy.
"I want it to warm up a bit for him," Collins said. "When the weather starts to change, I think he'll be better. To run him out there three or four days in a row, I think you're asking for problems. Our bullpen is starting to pick it up because our starters are going deeper into games. I think we've got some guys that can pick that role up right now."
Before his callup this season, Isringhausen had not pitched in a Major League game since 2009, when he was with the Rays. He had Tommy John elbow surgery later that season.
Scott Hairston is nursing back and neck injuries after crashing into the outfield fence during the series against Houston. He said after Sunday's game he had been diagnosed with whiplash, but is available.
Bobby Parnell and Angel Pagan will travel to Port St. Lucie, Fla., when the Mets begin their road trip through Washington and Philadelphia. Parnell has a localized blood clot in a finger on his pitching hand, and Pagan is recovering from a strained oblique.
