NEW YORK -- The Mets received a boost this season from the Orioles and Indians, last-place opponents who helped them march toward the top of the standings in the early months of summer.

Their Interleague opponents may prove a bit tougher next season.

In addition to hosting the Angels and Athletics at Citi Field and facing the Yankees twice in the annual Subway Series, the Mets will travel to Detroit and Texas for Interleague series in June. Those series add a degree of difficulty and highlight the Mets' 2011 schedule, which Major League Baseball officially released on Tuesday.

In a change to the schedule, Mets will open the season on Friday, April 1, in Miami, a two-hour drive from their Spring Training complex in Port St. Lucie, Fla. Completing the season at Citi Field for the second straight year, they will close at home against the Reds on Wednesday, Sept. 28.

In between the Mets will navigate the best of the National League East and NL overall. Playing in Philadelphia on from April 5-7, April 29 to May 1 and Aug. 22-24, the Mets will also host the rival Phillies from May 27-29, July 15-17 and Sept. 23-25. They will travel to Atlanta for three-game series beginning April 15, June 14 and Sept. 16, and will host the Braves from June 3-5, Aug. 5-7 and Aug. 26-28.

The Mets will also host a Memorial Day game against the Pirates after welcoming the Phillies to Citi Field earlier that weekend.

The jewels of the schedule, as usual, are the Subway Series dates against the Yankees -- May 20-22 at Yankee Stadium and July 1-3 at Citi Field.

The Mets will also make two West Coast trips in the height of summer -- one to Los Angeles and San Francisco from July 4-10, the other to Phoenix and San Diego from Aug. 12-17.
