NYM@WSH: E. Young hits a two-out RBI double to left

NEW YORK -- In the likelihood that Eric Young Jr. needs to head the disabled list, general manager Sandy Alderson said, the Mets are calling in outfielder Matt den Dekker from Triple-A Las Vegas. As of Sunday night, no official transaction had been made.

Young had to sit out Sunday's doubleheader against Arizona with a right hamstring "issue," as Alderson put it. Manager Terry Collins said Young felt it flare up most when he stole second base in the seventh inning of Saturday's 3-2 loss.

"I just came in one day and it wasn't feeling that good," Young said.

Collins ruled Young out for the doubleheader as a precaution before he had a chance to see a doctor.

"His game is his legs, so I certainly didn't want to take a chance," Collins said.

den Dekker, 26, has 27 games of Major League experience, all with the Mets in 2013. He hit .207 with a .270 on-base percentage and 23 strikeouts in 58 at-bats while seeing time at all three outfield spots, but mostly center field.

In 47 games with Las Vegas this season, den Dekker is hitting .269 with a .326 OBP and .421 slugging mark.

Recker has career day at plate in finale

ARI@NYM: Recker collects four hits in win

NEW YORK -- Anthony Recker's Sunday didn't get off to the most orthodox start -- he entered as a ninth-inning pinch runner for fellow catcher Juan Centeno -- but by night's end it was one he'll remember for a while.

He got the start in Game 2 of the doubleheader against the D-backs at Citi Field and went 4-for-4 with a double. The only run he scored put the Mets on top for good in their 4-2 win.

"The baseball gods were good to me," Recker said. "They gave me a couple of knocks. I'll take it."

The four hits are a career high for Recker, and it's the first time he's had that many in a single game at any level since he went 4-for-5 on Aug. 11, 2010 for the Triple-A Sacramento River Cats.

Recker has started seven of the team's 11 games since Travis d'Arnaud went down with a concussion, splitting time with Centeno. His four base knocks Sunday improved his average on the season from .194 to .242.

Black hopes new delivery can help Mets

STL@NYM: Black holds Cards hitless in shutout eighth

NEW YORK -- Vic Black's stay in the Majors lasted only a day, but armed with a slightly new delivery and an ability so far this season to prevent runners from crossing the plate, he's hoping to make an impact the next chance he gets.

"One day is better than no days," Black said with a smile on Sunday. "Whether or not I stay is up to [the Mets' brass] but I'll definitely try to make it as hard on them as possible."

Black was with the Mets as the 26th man for their doubleheader against the D-backs, up from Triple-A Las Vegas where he posted a 1.45 ERA and 1.55 WHIP in 18 2/3 innings.He was sent back down after the doubleheader.

After dealing with a neck issue that kept him out of action for about a week early last month, Black changed his delivery. Instead of standing narrow and holding his hands at his chest in the set position, he now keeps his feet about four feet apart and has his hands down at his waist.

The new form is a return to the way Black threw before Mets pitching coach Dan Warthen had him change last September.

It hasn't solved Black's control issues -- he has issued 17 free passes with Las Vegas -- but it did give him some velocity back.

"I still walk guys. That's not a surprise," Black said. "My job is to get outs [and] not let runs score. And I feel like I have been doing that quite well, so I continue to take that approach and run with it."

Black has indeed done that well, but whether or not he can get away with the frequent walks in the Majors -- where batters are much more likely to make him pay -- remains to be seen. In 18 big league games last season, Black allowed seven runs in 17 innings for a 3.71 ERA while walking six and striking out 15.

"If he gets in, I want to see strikes," manager Terry Collins said. "Certainly his stuff -- we saw it last September -- outstanding stuff. If he throws it near the plate, he gets outs."

Worth noting

Dillon Gee, who is nursing a strained right lat, was unable to throw a bullpen on Sunday. There is no set timetable for his return, so rookies Rafael Montero and Jacob deGrom appear to be in the rotation indefinitely.

"We'll back him off a little bit," Alderson said.

• d'Arnaud went 1-for-3 and caught five innings in the first game of his rehab assignment with Double-A Binghamton on Sunday. After grounding out to second in the first inning, d'Arnaud homered on a fly ball to left field in the third and flied out to right field in the fifth. d'Arnaud has been out since May 13 with a concussion.
