Worth noting

• Third baseman David Wright (strained left intercostal) returned to Minor League action on Thursday, playing five innings at third base for the first time since the World Baseball Classic. Wright finished 0-for-3 with two walks and two runs scored, telling reporters in Port St. Lucie that he hopes to return to Grapefruit League play on Friday. That would all but ensure that Wright is ready for Opening Day.

• The Mets announced that "Shameless" star Emmy Rossum, a New York City native, will perform the national anthem on Opening Day at Citi Field. Rossum will sing alongside the Scholars' Academy children's choir from Far Rockaway, Queens, as the Mets honor various servicemen and volunteers for their efforts during Hurricane Sandy.

Murphy's ribs fine after making spring debut

VIERA, Fla. -- If there was any doubt as to the state of Daniel Murphy's strained right intercostal muscle, the second baseman erased it on a wild play in the first inning Thursday. Moments after singling on the first big league pitch he saw all spring, Murphy tagged from first to second, belly-flopping onto the base to beat the tag.

"I bit the ground, but I felt pretty good on it," Murphy said, joking that he "tackled" the bag. "It was the right play."

Murphy finished 1-for-3 during the Mets' 5-1 loss to the Nationals in his long-awaited Grapefruit League debut, which came approximately six weeks after he strained his intercostal in the early days of camp. Though he punched a broken-bat single into right field in his first at-bat, Murphy called that hit "trash." More encouraging, Murphy said, was the line drive he smashed directly at the second baseman in his second at-bat, and the sharp foul he hit before striking out in his last.

Most heartening, of course, was the fact that Murphy felt no twinge in his side, no pain, no discomfort -- nothing.

"That was the good thing about today," Murphy said. "I didn't feel it at all and I was able to just play the game. Now I'll just use these next two days to get my legs underneath me as much as possible, and I'm looking forward to going north."

As long as Murphy remains healthy, he will appear in each of the Mets' final two Grapefruit League games, against the Cardinals and Orioles. Though facing Nationals left-hander Gio Gonzalez was a good first test for Murphy, he believes seeing as much Major League pitching as possible over the next two days will be crucial.

"He needs to [push it]," manager Terry Collins said. "He needs to a little bit, otherwise he stays here. He's got to show us that he's ready to play. He's got to show that he's not going to have a problem swinging the bat or with his mobility, because he hasn't played much. You've got to go play."

Most significant will be making sure that the ribcage discomfort, which has been a part of his life for a month and a half, does not resurface.

"I can't just show up and play without getting some work done on it just to make sure it's ready, but the training staff's done a great job," Murphy said. "I feel good. I felt good today. We'll see how I feel tomorrow."

Collins not fretting over Tejada's lackluster spring

VIERA, Fla. -- Well aware of shortstop Ruben Tejada's big league track record and future potential, manager Terry Collins refuses to fret over the 23-year-old's unproductive spring.

"When the bright lights are on," Collins said, "when there's people sitting in the second deck, what they do in those circumstances is what I look at."

What Tejada has done is hit .287 over the past two seasons, reaching base often enough for the front office to avoid searching for an offseason upgrade. Defensive metrics reveal that Tejada has been a tick above average with the glove over that span, giving Collins all the more reason to commit to him.

But Tejada is batting only .080 in his second spring as a full-time starter, totaling four hits in 58 plate appearances. Since homering off Stephen Strasburg in his first Grapefruit League at-bat on Feb. 23, Tejada has gone 3-for-49 with one extra-base hit.

Tejada has worked recently on his contact hitting, trying to spray pitches to right and center field while avoiding fly balls. Tejada also claims he is comfortable at the plate, even if the results have yet to appear.

"I feel good," Tejada said. "I've felt good the last two weeks. I've just got to keep going the same way, try to make good contact so I'm ready for next week."
