Buck was thrown out rounding third, but Collin Cowgill, pinch hitting for Harvey, extended the Mets lead to 4-0 with a two-run homer to left field.
"I think I pitched fairly well, but they took advantage of a couple mistakes," Westbrook said. "I left a couple of balls over the plate, and I was not able to execute all my pitches, so in that way it wasn't my best day."
Mets starter Matt Harvey finished his spring on a high note, giving up three hits and no runs in four innings. He walked two batters but struck out four. The right-hander pitches in Game 2 on Wednesday.
"I couldn't be happier with the spring, how it went and how my body feels going into the season and we're all looking forward to heading up north," Harvey said. "There were some down times, but there were some really good stuff. My curveball is right where I want it. I was able to fine-tune some pitches today, and getting back out there is something I'm definitely looking forward to Wednesday."
