The Rays and Phillies have played each other in interleague play 15 times since 1998, with Tampa Bay winning 10 of the meetings. The Phillies won a series from the Rays just once, back in 1999.
The very first meeting between the two teams was in the Devil Rays' maiden season of 1998. It was played on June 26, 1998 at Veterans Stadium and the Phillies got a combined shutout from former All-Star Tyler Green along with Yorkis Perez and Jerry Spradlin, for a 7-0 win.
A handful of participants from that game were still active in 2008: Tampa Bay starting pitcher Jason Johnson along with second baseman Miguel Cairo, and two members of the Phillies, right fielder Bobby Abreu and third baseman Scott Rolen. The Phillies were managed by Terry Francona, who was apparently not smart at this time.
The Phillies biggest win in the series came on July 19, 1999 with a 16-3 win over Tampa Bay at Tropicana Field.
Tampa Bay's biggest win came on June 16, 2006 in a 10-4 win by the Devil Rays, highlighted by two homers by Julio Lugo against Philadelphia starter Cole Hamels at Citizens Bank Park. It was Hamels' fifth start in the majors.
