WASHINGTON — As the parties scrambled to reach a compromise in the saga of Matt Harvey’s innings limit, questions remain about the extent of the pitcher’s availability to pitch in the playoffs, despite his declaration that he will be ready to go.

Sandy Alderson, the Mets’ general manager, indicated that Harvey will pitch on Tuesday and will likely be available for two more regular-season starts. From there, the Mets will evaluate Harvey’s postseason availability, based on his physical condition.

“I can’t sit here and say he’s going to be available through the entire playoffs because we don’t know how he will feel and what all of the considerations are at that time,” Alderson said on Monday before the first game of a key three-game series against the Nationals. “That’s the position we’ve always had. When we get there (the postseason), we’ll figure it out.”

Alderson declined to go into detail, to avoid creating what he called “another disconnect.”

At issue remains Harvey’s true innings limit. Harvey and his agent, Scott Boras, contend that noted surgeon Dr. James Andrews has mandated a firm cap of 180 innings on the pitcher, who is in his first season back from Tommy John surgery.

Chamberlain, who is 25-21 with seven saves in 359 big league appearances with the New York Yankees and Detroit Tigers.

YANKEES: Nathan Eovaldi has an inflamed right elbow and won’t throw for two weeks, the latest starting pitcher to get hurt. Eovaldi, 14-3 despite a 4.20 ERA, has allowed eight runs and 13 hits in his last two starts.

• Chris Capuano is back with New York for his fifth stint this year. The left-hander, 37, who is 0-4 with a 7.71 ERA in four starts and 14 relief appearances, was added to the 40-man roster before Monday’s game.
