September 24, 2001 We all know about the four or five Mets who had hits in their lone plate appearances. However, I think Kenny Greer is the only Mets pitcher to have a winning percentage of 1.000 in his only Met mound appearance.
As Casey Stengel said, you can look it up!
The 26th Met
February 22, 2002 It was the second to last game of the Mets home schedule. The Mets had already lost 103 games in that ugly '93 season. The weather was seasonably cold on that Sept 29th evening. Little did I know at the time it would last 17 innings! As the game remained scoreless through 16 innings against the Cardinals, on came the rookie pitcher Kenny Greer to pitch the top of the 17th inning making his major league debut. He had been recently aquired days earlier in a trade with the Yankees in exchange for Frank Tannana. Well I was only one of about 100 fans still on hand to watch Greer pitch what would turn out to be his only game in a Mets uniform. The Mets scratched out a run in the bottom of 17th making Greer the winning pitcher, and sending a shivering crowd of 100 home very happy. Of the many Mets games I have attended in my life, this one game stands as testiment to my dedication to the Mets. Although he might have picthed in only one game and for one inning as a New York Met, Kenny Greer's performance might rank up their in all-time trades between the Mets and Yanks that worked out in our favor! --The 26th Met
December 30, 2002 His one and only win in his entire ML career came in his first appearance -- in the 17th inning of a 0-0 game! Jeff Kent finally ended it in the bottom of the inning by doubling over Ray Lankford's head, scoring Eddie Murray.
