What active players have won World Series with two teams? Here are some:
Jose Molina (2002 Angels, 2009 Yankees)
Johnny Damon (2004 Red Sox, 2009 Yankees)
Mike Lowell (1998 Yankees, 2003 Marlins, 2007 Red Sox)
Josh Beckett (2003 Marlins, 2007 Red Sox)
A.J. Burnett (2003 Marlins, 2009 Yankees)
Jamie Burke (2002 Angels but did not play that season, 2005 White Sox)
Orlando Hernandez (1998 and 2000 Yankees, 2005 White Sox) is trying to come back
Damaso Marte (2005 White Sox, 2009 Yankees)
If you count Burke (I'm assuming he was injured in 2002) then he is the only player I named to do it without winning a World Series with the Yankees, Red Sox, or Marlins. Thanks to his first 15 career plate apperances in 1998, Lowell is the only active player to have won World Series with three teams (baseball-reference gives him credit for 1998).
Are there any more active players who have won World Series with two teams?
