"It means a lot. It's a relief. It's just a burden off my shoulders,'' the 25-year-old Niese told reporters after the Mets' 1-0 win over the Atlanta Braves on Thursday. "It's something that I don't have to think about. When I go out there to pitch I can just go out there, pitch, have fun, help my team win.''

Pitching for the Mets in 2011, Niese picked up an 11-11 record with a 4.40 ERA. Over the past four seasons with the Mets, he has a combined record of 22-23 with a 4.39 ERA. Niese is just one of the young players the Mets have locked up as they attempt to recover from the Bernard Madoff Ponzi scheme and try to get back to being a playoff-contending club.
