Marlon Byrd believed he was capable of still playing baseball, but he was curious if a major league club was going to offer him a contract.

The 35-year-old Byrd endured a brutal 2012 season — traded by the Cubs, being suspended after failing a drug test, being released by the Red Sox and batting a lowly .210 for the year. He didn’t play after June 8, even after being reinstated following his suspension. He didn’t have a team for 2013 through January.

“I wondered if a team or any organization was going to take a flier on me,” Byrd said. “I could still play. If a team doesn’t give me a job, there’s not much you can do.”

Byrd isn’t sure whether any other team bid for him, but said when his agent informed him of the Mets’ interest, he said, “Please, get this done.”

On Feb. 1, he signed a minor league deal with the Mets, then ripped up the Grapefruit League and started on Opening Day in right field.

Byrd’s walk-off two-run single down the left field line in yesterday’s ninth inning thrust the Mets to a 4-3 win over the Marlins and ranks as the biggest hit on their season-opening homestand. The Mets took the final two games against Miami, have won their two opening series of the season for the first time since 2006 and are now 4-2 on the year going into Philadelphia tonight.

“You want to win series, especially at home,” Ike Davis said, addressing the difference of being 4-2 instead of 3-3. “It means you’re two games above .500 instead of even.”
