FLUSHING, NY - Terry Collins has now managed seven games for the New York Mets. Friday in the opening home game loss to the Washington Nationals he said frustration was not an issue this early in the season. Perhaps he is thinking differently now after an 11-inning 7-3 loss to Washington Sunday afternoon at Citi Field.Frustration though won’t come from Collins, at least this early. But his bullpen may change the mood fast after they spoiled a terrific second outing for starting pitcher Chris Young.  After Young was removed after seven innings, giving up one run, the pen and a defensive miscue opened the door for Washington to take the rubber game.“He got us to where we wanted to go,” said Collins about his starter who retired 15 of 21 on fly balls. “He got us to the eighth inning and we couldn’t hold it for him. It’s a shame, but he pitched great.”  But the pen did not, and that may be leading to early season frustration for the news Mets manager.An outfield error for the second straight game also gave this one to the Nationals in the eighth inning. Lucas Duda misjudged a ball by leadoff hitter Ivan Rodriguez that led to a double. D.J. Carrasco then gave up a walk and a single. That would tie the game at 3-3.From there the Mets pen took it from there, maybe more horrific than the pen that blew so many games in 2010 at Citi Field. And it wasn’t Frankie Rodriguez who retired one batter. It was Carrasco, Taylor Buchholz, and Blaine Boyer who added to the pen woes of the Mets that gave up 11 walks and 10 hits in 11 innings in the three-game series.Four runs in the 11th including a tie breaking single by Rodriguez, and a three-run homer from Laynce Nix off the loser, Boyer( 0-2) made Young’s outing a short term memory. And most of the 35,157 fans left in the ballpark headed for the exits, changes were made on the roster, and Collins offered some frustration.Duda was optioned to Triple- A Buffalo after the game and changes were made in the pen. Pitchers Ryota Igarashi and Jason Isringhausen, the 38-year old home grown Met, signed to a spring training contract will be at Citi Field Monday evening when the Mets begin a four-game series with Colorado.“I guess you’ve got to convince them that they got to get beat by somebody swinging the bat,” commented Collins. After seven games, the (3-4) Mets have plenty of time to find a way to get the outs in late innings. Carrasco has been doing the job, so has Bobby Parnell for the most part.Bur Collins said he avoided using Parnell after two straight appearances out of the pen.  On using Rodriguez to get an out in the eighth, Collins said, “We are not going to wear Frankie out.”  Not using K-Rod has nothing to do with the new performance clause in his revamped contract of innings pitched.“This is the big leagues and they’ve got to be able to land some pitches,” offered Collins when asked about concern of the Mets pen not able to pick up a win for Young.  “I’m not saying you’re never going to walk somebody, but we’re walking at too high a rate right now.”Young who spent most of last season with San Diego on the disabled list, due to a sore right shoulder, had a second outing with his new team in his first start at Citi Field, “It was a great experience to be out there,” he said about the crowd and view of the ballpark.His shoulder felt fine on another cold day at Citi Field, but Collins opted for his pen, going to Carrasco, after Young threw 108 pitches. “You have to have a short memory and it’s something to build on,” he said about the day.But Collins also was concerned about the defense. Daniel Murphy is still learning how to handle second base. He replaced Brad Emaus and Rodriguez got a hit past him in that 11th inning. Said Carrasco, “Its horrible man to just come in there and give the game away like that is very frustrating.”Frustrating right now is the word for the Mets after seven games. Collins won’t say it, but if things don’t get better this week against the Rockies you get the feeling the Mets manager will also be using that word more often.e-mail Rich Mancuso: Ring786@aol.com
