WASHINGTON -- New York Mets general manager Sandy Alderson says the plan for pitcher Matt Harvey could include regular season starts down the stretch against the New York Yankees and Washington Nationals.

Alderson also said Wednesday that the NL East leaders haven't determined how they might use Harvey in the postseason. The Mets went into Wednesday with a six-game lead over Washington.

The Mets host the Yankees in an interleague series Sept. 18-20 and close the season at Citi Field against the Nationals on Oct. 2-4.

Harvey gave up a career high-tying seven runs in 5 1-3 innings Tuesday night during New York's 8-7 win against the Nationals.

Harvey has thrown 171 2-3 innings this year, his first season since undergoing Tommy John surgery in 2013. Harvey and the Mets want to keep his innings count around 180 to 185 for the regular season.

Alderson said he expects to talk with Harvey's agent, Scott Boras, and the pitcher's surgeon, Dr. James Andrews, to solidify their plan.

Alderson said the Mets are considering skipping a start for Jacob deGrom in the final weeks.
