Matt Harvey has struggled to begin the season and is still searching for answers.

"I'm giving up more hits, more runs -- kind of everything -- more than I ever have," the New York Mets right-hander said. "Obviously, it's frustrating. I've got to keep working."

Harvey was charged with three runs on eight hits and two walks in 5 2/3 innings Tuesday. He dropped to 2-4 with a 4.76 ERA.

"Right now, I'm not feeling good with my mechanics. I'm not feeling good throwing the ball," Harvey said. "It's frustrating. I think I've said it before: I'm the one who is most frustrated here about what's going on. It's been a frustrating start, but we have a long way to go."
