New York – David Wright was released from the hospital Sunday morning and watched his team at home. After the Mets got their fourth walk-off win of the season on a base hit form Daniel Murphy in the ninth, GM Omar Minaya announced that Wright was going on the 15-day disabled list with post concussion syndrome.“He wants to play and the decision from our medical staff and my self was to stay home,” explained Minaya. Wright was hit by a Matt Cain fastball Saturday and has the usual headaches associated with a concussion.  The Mets are being cautious about Wright, their team leader, who missed one game all season and don’t want a recurrence of the Ryan Church concussion episode of last season.Minaya has had his share of bad news all season. The injuries to his starting lineup and pitching staff have been a reason why the Mets are not in contention, and now Wright, who could miss the entire season pending on how long the recuperation takes place. “Based on the recommendations of our doctors and the specialist,” said Minaya when asked why Wright was put on the DLThe mood in the Mets clubhouse Saturday was all about the concern for Wright. It remained that way before and after the game Sunday. Luis Castillo provided the Mets with maybe the longest home run at Citi Field in a 3-2 win. With two outs in the fifth inning he hit a Jonathan Sanchez pitch to the second deck in left field, his first home run since May of 2008.And Mike Pelfrey, perhaps is back on the right track as he provided the Mets with his best pitching effort of the season. He gave up two runs on five hits in 7/2-3 innings and struck out eight. He has allowed only four runs in three starts against the Giants but only has one win to show for it.Francisco Rodriquez (3-4) pitched a perfect ninth inning out of the pen and got the win.  Murphy, with his first career walk-off winning hit, was the hero for now. But the Mets clubhouse had all their thoughts with Wright.“Every time you get a W it’s a good feeling,” said Murphy, “but we all have our thoughts with David.” Jeff Francoeur opened the ninth with single deep in the hole off losing pitcher Sergio Romo (3-2) and scored on the Murphy hit after Fernando Tatis sacrificed him to second.It was that rare type of win for the Mets who took their second game in the four-game series that concludes Monday evening.e-mail Rich Mancuso:  Ring786@aol.com
