D'Arnaud activated from seven-day disabled list

NEW YORK -- Catcher Travis d'Arnaud spent Wednesday morning traveling to New York City in anticipation of coming off the disabled list. The Mets officially activated him after Wednesday's game, optioning Juan Centeno back to Triple-A Las Vegas.

D'Arnaud, who had been on the seven-day DL since May 15 with a concussion, caught two innings at Double-A Binghamton on Tuesday before that game was suspended due to rain. He appeared in a total of three Minor League rehab games at Binghamton, finishing 1-for-8 with a home run and a walk.

Prior to his concussion, d'Arnaud was batting .196 with three home runs in 31 games for the Mets. He sustained the injury when Yankees outfielder Alfonso Soriano struck him on the top of the helmet with a backswing in a May 13 game at Yankee Stadium, experiencing concussion symptoms for approximately one week.

Mejia seamlessly adapting to ninth-inning role

NEW YORK -- When Mets manager Terry Collins gave Jenrry Mejia the keys to the ninth inning earlier this month, he did so with slight reservation. Until Mejia could prove his ability to appear in back-to-back games, and perhaps even in back-to-back-to-back games, Collins was not going to name him the closer.

Two weeks into his audition, Mejia has passed most of those tests. After pitching in both halves of Sunday's doubleheader, Mejia returned two days later to throw two shutout innings against the Pirates.

"I thought [Tuesday] was a perfect example of a guy who has said, 'Hey, look, I'll do what I have to do to help this team,'" Collins said. "The kid just said, 'Give me the ball,' and that's pretty impressive. He's going to take to this pretty easy."

Since the Mets unofficially moved Mejia into the closer's role, the right-hander has given up one unearned run in eight innings, striking out seven and walking three. But the Mets anticipated success from Mejia in his transition from rotation to bullpen; what they were unsure about was his durability. Mejia fueled those worries by speaking openly about his fear of sustaining an arm injury if he pitched too often in relief.

If Mejia still has those fears, he is no longer voicing them. Pitching as often and effectively as Mejia has is giving him new confidence, to the point that both he and Collins believe he is ready to try pitching in three consecutive games.

"Now, I'm ready for any situation that comes up," Mejia said. "I'm ready for everything."

Wright takes aim at personal 162-game season

NEW YORK -- The most pressing question surrounding David Wright heading into this season was his ability to stay healthy. After sustaining major injuries in two of the previous three seasons, Wright spent his offseason brainstorming ways to stay on the field.

It is worth noting, then, that Wright has started every game that the Mets have played this season, missing a total of two innings during a blowout in Anaheim last month. He is talking openly, albeit skeptically, about appearing in all 162. Even if his offensive numbers are not where he wants them to be -- Wright's walk and home run rates are both way down -- he is achieving the one goal that makes all others possible.

"If I feel good enough, then that obviously would be a nice number, a nice goal," Wright said of playing in all 162 games. "But if taking a day off would be better for me and the team in the long run, then I should take the day."

Earlier in his career, Wright had little trouble staying healthy, playing in 160-plus games in three of his first four full seasons. But the third baseman's durability has taken a hit in recent years, due mostly to the injuries -- a stress fracture in his lower back in 2011 and a strained hamstring in '13 -- that have plagued him.

Manager Terry Collins has been searching for an opportunity to give Wright a day off, but so far has resisted. That respite could come on the Mets' upcoming 11-game road trip, though Wright will not be the one to ask for it.

"It's always good in theory to try to take a blow here and there," Wright said. "But then when you get in the grind of it, especially with how we've struggled lately, I've never been one to go initiate it. I have to be told to take an off-day. It would be a different story if we were playing well and I felt comfortable taking a day here or there."
