Baseball commissioner Bud Selig announced Tuesday that the Phillies-Blue Jays series will be played in Philadelphia because of the G20 Summit.

The three-game series June 25-27 will be relocated from Toronto’s Rogers Centre to Philadelphia’s Citizens Bank Park because of security issues for the G20 Summit. World leaders will gather at the convention center next to the Toronto ballpark.

The game would have been ace Roy Halladay’s first return visit after he was traded to the Phillies in the offseason.

The rescheduled games will be considered home games of the Blue Jays, who will bat last, and the DH will be used.
