Roy Halladay, who is recovering from a strained right latissimus dorsi, continues to throw long toss and is "doing fine," Dubee said. Dubee said the club has an idea when Halladay will begin throwing off a mound, but didn't disclose any more details.
A Phillies win and a Marlins loss on Saturday would put Philadelphia in fourth place in the National League East for the first time since May 28.
With Friday's game postponed until Sunday, Saturday's game marks the first time the Rays are playing a game at Citizens Bank Park since Game 5 of the 2008 World Series, when Brad Lidge closed the game by striking out Eric Hinske.
After hitting the ball extremely well with Class A Clearwater, Cody Asche was promoted to Double-A Reading on Saturday. Asche, a third baseman, hit .349 with two home runs and 25 RBIs in 62 games for the Threshers.
Manuel was one win from his 900th career victory entering Saturday.
It's possible a 26th man could be in uniform for the Phillies on Sunday against the Rays at Citizens Bank Park. In a rule established in the most recent collective bargaining agreement, clubs can have 26 players on the roster for day-night doubleheaders that occur at least two days after the original game is rained out. The Phillies have not yet said if they will take advantage of the rule. If they do, they would likely promote a player from Triple-A Lehigh Valley, which is currently in the midst of a three-game series at Columbus.
