PHILADELPHIA – Terry Collins was curious about how his phenom, Matt Harvey, would pitch Monday night. The Mets’ manager had quoted Sandy Koufax over the weekend, saying that a pitcher’s first start of the season is adrenaline-fueled; the second start is the pitcher’s true self. Harvey showed himself to be tough and resilient. The 24-year-old fought his fastball most of the night, but was still able to dominate the Phillies, just as John Buck expected. The veteran catcher hit a three-run home run as he teamed with Harvey to beat two-time Cy Young Award winner Roy Halladay, 7-2, at Citizen Bank Park.
