At the end of July he also had a 12 strikeout performance against the Phillies at Shea Stadium. In September as the Mets faltered Perez did as well after starting out the month with a win he had no other decisions along the way.
His best outing was the last game of the season in the final game of Shea Stadium’s history. He allowed just two runs striking out six Marlins exiting in the 6th inning, but was not the pitcher of record as the Mets tied it in the bottom of the inning before losing it later on.
