Mets mulling decision on Mejia's rotation fate

NEW YORK -- Decision time is looming for the Mets and their rotation.

Manager Terry Collins spoke with general manager Sandy Alderson on Sunday regarding Jenrry Mejia's rotation spot. But he remained as coy -- as he has been all weekend -- when asked if Mejia will make his next start, not confirming or denying it.

Alderson refused interview requests both before and after Sunday's game, leaving the situation in flux.

One of the factors Collins is considering is that Mejia is next scheduled to pitch Wednesday against the Yankees -- not exactly ideal conditions for a prospect such as Rafael Montero to make his big league debut.

"The answer to me is yes, it will have something to do with it," Collins said of the Subway Series pomp and circumstance. "It's going to be against Masahiro Tanaka. It's going to be here. So I think you've certainly go to take it into consideration."

Mejia certainly has more experience than Montero, having faced the Yankees previously in his career. But he has been struggling for weeks, posting a 9.82 ERA in his last three starts.

If not Montero or fellow rookie Jacob deGrom, the Mets could default back to Mejia or to Daisuke Matsuzaka, who is not stretched out as a starter. But Collins indicated that the two innings Matsuzaka pitched in relief Sunday may preclude him from starting. Top prospect Noah Syndergaard, meanwhile, has been inconsistent at Triple-A Las Vegas and is not an option at this time.

So even if the Mets do not consider Mejia an ideal choice, he may be their only option if they are unwilling to dip into the Minors.

"I think it's going to pretty exciting when they get here … but it's got to be the right time," Collins said of Syndergaard, Montero and the club's other top prospects. "I think that's where Sandy's real good at having a feel for what's the right time."

Murphy's homer with pink bat spurs Mets' rally

NEW YORK -- Though Daniel Murphy was dressed in a New York Rangers sweater after Sunday's win over the Phillies, he did not plan on joining a pack of his teammates at Madison Square Garden for the game.

Murphy had Mother's Day duties to attend to.

Then again, the second baseman had already celebrated earlier Sunday, when his two-run homer with a pink bat helped spark the Mets' three-run comeback in the ninth en route to their 5-4, 11-inning win over the Phillies. One of several Mets players to use such the specialty lumber, Murphy came through with the most significant pink-tinted hit at Citi Field.

"You just go out there and try to play as hard as you can," Murphy said.

As they do every Mother's Day, Major League players recognized the holiday by using pink bats, wristbands, cleats and other accessories. After the game, an authenticator came to Citi Field's clubhouse to collect the gear, which will be auctioned off on MLB.com to benefit the fight against breast cancer.

Murphy was not the only Mets player who delivered a Mother's Day gift. Though rookie Eric Campbell did not use a pink bat, he planned to give the ball from his first big league hit -- a single off Cole Hamels in the fourth inning -- to his parents for display in their home.

"She's going to like that one for sure," Campbell said, smiling.

Granderson among four regulars getting rest

NEW YORK -- The Mets' lineup assumed a different look for Sunday's series finale at Citi Field, with Curtis Granderson among four regulars sitting idle against Phillies left-hander Cole Hamels.

Manager Terry Collins saw the game as an ideal chance not only to rest Granderson, who had reached base safely in 15 of his last 17 games, but also to insert Eric Young into the lineup. Young, who had started just one of the Mets' first nine games since Juan Lagares' return from the disabled list, finished 3-for-6 with two stolen bases.

"It's been hard for him," Collins said. "But he's a pro. We talked in Colorado. He said, 'I totally understand what's going on and I'll be ready when you need me.'"

Collins also rested first baseman Lucas Duda, shortstop Wilmer Flores and catcher Travis d'Arnaud against Hamels, though all but Flores eventually appeared in the game. He and reliever Gonzalez Germen were sidelined due to illness, and may not be available for Monday's game either.

"I don't even think Wilmer put his uniform on," Collins said. "I don't know what it is, but we've had some pretty sick guys this week."

For Duda, who also sat out Friday due to food poisoning, such days of rest won't come often. Collins plans to start him Tuesday against Yankees left-hander Vidal Nuno, as well as regularly versus right-handed pitching. He should play in all four Subway Series games against the Yankees, either at first base or designated hitter.

Though Collins has hinted in the past that he would eventually like to shift Duda into the cleanup spot, he said that with the way Granderson has performed lately -- seven RBIs in nine games, thanks in large part to four multihit games in his last nine starts -- a change is not imminent.
