New York- So much for talk that the New York Mets could not hit the home run at Citi Field, or win many ballgames in their home park. After their 8-4   win over the Arizona Diamondbacks on Easter Sunday, taking a three-game sweep, the Mets have won four consecutive games after taking the final game of the three- game series that started the stand earlier this week against the Houston Astros.And this season high winning streak, the longest since last September 13-16 of last season, was done with good pitching and timely hitting. Plenty of two out hits and getting Jason Bay back in the lineup seemed to propel the offense. Jonathon Niese (1-3) pitched seven solid innings, snapping a six-game losing streak in the series sweep Sunday, and Mets starting pitching in the six games went 6-0 innings or more.Plus the Mets offense produced three more home runs Sunday, two by David Wright and one from Jason Pridie. It was the first Major League round tripper for Pridie. The 27-year old center fielder was called up from Triple-A Buffalo Friday when Angel Pagan went on the 15-day disabled list with a strained left oblique muscle.So what has transpired in the past few days? Good pitching and hitting will win ballgames, and all of a sudden Citi Field has become home run friendly for the Mets. It has the team riding with optimism as they head for a six game trip to Washington and Philadelphia on Tuesday. And their most effective starter in the young season, Chris Young comes off the disabled list and will open game one of the series against the Nationals.“It’s really good,” said Mets manager Terry Collins. When the Mets were 5-13 earlier in the week, and with the worst record in baseball, Collins was frustrated and concerned but said, “I promise you it will get better.” It certainly has improved because David Wright has also come around at the plate. Carlos Beltran went 9-for-23 with a home run and three RBI in six games, Ike Davis reached base four times Sunday and had three home runs, two doubles and six RBI in the six games.In the streak New York scored 27 runs and outscored the opposition 27-10. “I think the brightest sign has been our starting pitching,” added Collins. “It’s really stepped up here and gotten us to where we need to get to. I think you see a difference in the bullpen where they can just pitch to certain guys. I think it makes everyone more comfortable.”The pen found itself a bit when Collins used the combination of rookie Pedro Beato, the veteran Jason Isringhausen and closer Frankie Rodriguez to close the door when the Mets had the lead in three of the six games. Sunday, Collins went with D.J. Carrasco who gave up a run in the eighth, Tim Byrdak and Ryota Igarashi. He credited the use of starters Chris Capuano and R.A. Dickey out of the pen in Atlanta on the last road trip as to a reason why starters Capuano and Dickey had success this week.“We got some really big hits, two-out hits and that makes a difference,” he said. His team scored five two-out runs in the series finale with Arizona, and the day before had six two-out runs. And Wright has been a major catalyst of the resurged offense. His second home run Sunday, fifth of the season, came with two outs and no runners in in the fourth inning that gave the Mets an 8-1 lead.New York scored two runs off Arizona starter Armando Galarraga (3-1) in the first and four more runs off him in the third. In the past four games, Wright has home runs and he credits the starting pitching for the 4-2 homestand. “We’ll go as far as our starting pitching carries us,” he said.His home run in the fourth was high and got over the fence on the left field line and right of the pole. “He’s tireless and when you hit the ball hard things are going to happen,” explained Collins regarding how Wright came around in the six games. “Even though I wasn’t getting good results I was getting good at bats,’ said Wright who also had a multi –home run game against the Diamondbacks last season on July 30th.Niese retired the first six Arizona hitters in the lineup and had good command with the fastball. He gave up six hits and three runs, of which two were earned. Collins and pitching Coach Dan Warthen said he was rushing his pitches in three previous starts. “Rushing is probably a good word to describe the problems,” said Niese. “I thought I’d take my time today.”New York also hit two more doubles.one by Beltran and at least one in 21 of their 22 games, fourth in the majors. So of the ball is not going over the fence at Citi Field, there are the extra base hits that led to runs on the homestand. The Beltran double, on his 34th birthday would lead to one of the four runs in the fourth inning and he started all six games.Four guys can cause damage in the lineup. Collins said Beltran. Wright, Davis and Bay are capable of doing that every game and also Jose Reyes is the catalyst leading off. It has led to optimism this week. But as Collins said, “There is a long way to go. Washington plays well and the Phillies are the Phillies.”Yes, Collins looks forward to Tuesday. Now the determination is, can the Mets continue the momentum as they leave their sudden friendly confines of Citi Field?Notes: After the game GM Sandy Alderson said the team optioned Carrasco to Buffalo to make room for Young to make his start Tuesday….Alderson also said that for the moment Dillon Gee, who got the win Saturday in game two versus Arizona, would not be sent down, though it is not determined if he will be in the rotation with the return of Young….And Alderson said, catcher Ronnie Paulino will stay on the disabled list as he is still sustaining problems with an oblique muscle pull while rehabbing down in Florida.e-mail Rich Mancuso:
