From Mets.com via the Mets Geek blog:
The New York Mets today added five players to their 40-man winter roster: Righthanded pitchers Brian Bannister, Anderson Garcia, Henry Owens and Yusmeiro Petit, and lefthanded pitcher Juan Perez. In addition, the Mets outrighted outfielders Ambiorix Concepcion and Todd Self to Norfolk (AAA) of the International League.
Perez, 27, signed a minor league contract with the Mets on October 28th after spending the 2005 season with Pawtucket (AAA) of the International League in the Boston Red Sox organization. In 40 games, he was 4-5 with a 4.50 ERA (31 earned runs in 62.0 innings pitched) with one save.
I'll have to go back and look at some old scorecards and see if I can find any great pitching performances by J.P. I heard he was a nice guy, great with the kids, etc. Best O' Luck, Juan! Have fun in NY!
PS: Trying to find a picture of Juan Perez the baseball player is like trying to find a Mike Johnson that works in insurance.
