Kaz Matsui pounded a grand slam against the Phillies last night to help the Rockies put Philly in a 2-0 hole in its best of 5 series.
This is just another instance of a player who was horrible with the Mets, gets traded, and then all of a sudden comes through in the clutch for his new team. Add Kaz Matsui to the list of Jeff Kent, Carl Everet, Jason Isringhausen, and others who did nothing for us while they were here but now produce for their new teams.
Then of course there's the opposite scenario. Players who were good and then come to the Mets and are awful. Actually this is a really long list which includes the likes of Mo Vaughn, Roberto Alomar, Frank Viola, Brett Saberhagen, Vince Coleman, Bobby Bonilla, Jeromy Burnitz, Cliff Floyd, Scott Schoenweiss, and of course TOM GLAVINE.
Now there are plenty more people that could be added to this list, but this is just off the top of my head. Please feel free to reminisce about other players in the comments.
