daniel murphy 2Daniel Murphy passed the audition and said it was worth the risk.

Murphy, playing for the first time in a major league game this spring because of a strained right intercostal muscle, singled in three at-bats against Washington’s Gio Gonzalez, played five innings and declared himself ready for Opening Day.

Had he kept playing minor league games until Monday and was re-injured, his DL stint would be backdated deep into spring training. Should he get hurt now the clock would be running and he could miss the first two weeks of the season at least.Considering how thin the Mets are, it didn’t seem worth the gamble, but it looks as if they dodged it, especially since he tagged up and advanced to second on a fly ball. Most guys don’t even think of such a play in the regular season, let alone the exhibition schedule.

“It was nice to slide,’’ Murphy told reporters. “It was nice to get the headfirst one out of the way.’’

Murphy understood the risks of playing in the major league game, but said he needed the speed of it to get ready for the season. Similarly, David Wright wants a major league game today against the Cardinals or Saturday for the same reason.

“The speed of the game is obviously going to be a little quicker here,’’ Murphy said. “I actually was pleasantly surprised at how far along I was, and not even on the base hit. That was trash. … It was good to face (Gonzalez). It was really good to face a lefty with some velocity like that.’’

Pain wise, Murphy didn’t feel anything, so it was a positive day all along.

Figuring Murphy wakes up tomorrow without any discomfort, he’ll play second against St. Louis and Saturday against Baltimore at Sarasota, Fla.

Adam Rubin of ESPN New York projects that Daniel Murphy and David Wright will be ready for Opening Day.

With Murphy back at second the dilemma is what to do with Jordany Valdespin, who has had a good enough spring to make the 25-man roster.

When Murphy was down and Kirk Nieuwenhuis out with a bruised left knee, Valdespin seemed a lock to make the team. But, with Murphy back, reserve infielder Omar Quintanilla better defensively, and Nieuwenhuis again in contention in center field and needing at-bats, Valdespin could be back to the bench, if not the minors.

“We’ve got to decide who’s going to play center,’’ manager Terry Collins said. “Therefore, we’ve got to get Kirk some at-bats.’’

Nieuwenhuis is batting only .094. Unbelievably, if he and shortstop Ruben Tejada are Opening Day starters, the Mets could have two hitters with averages below .100 (Tejada is at .080).

Meanwhile, Justin Turner, who was originally scheduled to make the trip to play Thursday, was held back at Mets camp to receive more treatment after he strained his left calf Wednesday.

“I don’t know anything other than they were not putting him on the field,” Collins said. “They were going to treat it and see how he is tomorrow.”
