For the first time ever, the New York Mets and Yankees played their home openers on the same day at the same time, and it turned out Monday was a good day to be an Amazin's fan.
The Mets had an easy time with the Padres at Citi Field, winning 11-2. The Yankees struggled to score against the Red Sox and lost 8-2.
Winning pitcher Jon Niese helped his own cause with an RBI single in the second inning.
"The adrenaline was pumping," he said after the game.
Centerfielder Collin Cowgill would then put the game out of reach with a grand slam.
"I'm an aggressive hitter. I like to go after the fastball and if they go out, they out," Cowgill said. "I'm just trying to get on base for the guys behind me."
One of the newer Mets, Marlon Byrd, helped out as well with a couple of hits and RBIs.
"You know we're going to have some ups and we're going to have some downs," manager Terry Collins said. "The one thing we're trying to do is establish some credibility amongst our fans."
Former Met Rusty Staub threw out the ceremonial first pitch and actress Emmy Rossum sang the national anthem.
The Mets also paid tribute to first responders who rushed to the aid of Sandy victims and are wearing commemorative patches on their uniforms to honor the victims of Newtown.
The roster for the Mets largely resembles last season. The team signed David Wright, whom they named the fourth captain in team history, to an extension that will keep him with the Mets through 2020.
However, the team did trade Cy Young Award-winner R.A. Dickey after they could not work out a new contract.
Johan Santana is also now out for the season, and likely will not play again for the Mets after he re-injured his pitching shoulder.
It was a far different story in the Bronx.
Fans began pouring out of the stadium around the seventh inning after a wash out at Yankee Stadium.
The Red Sox scored four runs off CC Sabathia in the second inning, tacked on an insurance run in the seventh and put the game away with a three-run ninth.
The Yankees' only runs were scored on a Francisco Cervelli two-RBI single in the fourth inning.
Second baseman Robinson Cano was struck out in the seventh inning with two Yankees players on base, crushing the hopes for a Bronx resurgence.
The Bombers ended last season on a sour note, getting swept in the American League Championship Series by the Detroit Tigers.
The Yanks are starting the season without a number of injured players, including Alex Rodriguez, Mark Teixeira, Curtis Granderson and Derek Jeter, who is coming back from a broken ankle.
"It's going to make a difference," said Sabathia. "I just couldn't stop the bleeding. You know, usually I can hold them for a run or two, but I gave up a couple base hits and that made a difference in the game."
"I struck out. That's part of the game. You go to the plate, nobody wants to strike out," Cano said. "I just put this behind me and get ready for Wednesday."
Alex Rodriguez is not expected to return to the Yankees until at least mid-season, and while the third baseman was not introduced to the crowd, he was on hand for opening day.
"I think this year we have a very special opportunity. This is my 10th year here in New York, first time we've been predicted to finish in last place, which is pretty crazy," Rodriguez said.
Yankees fans tried to stay positive after the deflating loss.
"I think it's going to be a great season," one fan said. "But I think we have to wait until July."
This will also be the final season in pinstripes for pitcher Mariano Rivera, who has announced he will retire at the end of 2013.
Before the game, the Yankees and Red Sox teams stood together to dedicate the game to the victims of the Sandy Hook Elementary school shooting.
The color guard presenting the flags was made up of police and firefighters from Newtown, Conn., and the names of the 20 children and six adults killed in Sandy Hook appeared on the giant screen in center field.
Former Yankee player and manager Lou Piniella threw out the first pitch and Broadway star Constantine Maroulis sang the national anthem.
The Giants and Dodgers were the last two New York baseball teams to hold home openers on the same day back in 1956.
