Lidge, 37, planned to sit in the bullpen during games and act as a sounding board. The former Phillies closer retired after appearing in 11 games with Washington during the 2012 season.
"Hopefully, I'll be able to throw some knowledge at guys and relate some of my experiences, whether it's their first spring training or they're trying to make the team," he said. "I think I have a lot of experience in those areas. Hopefully, I can relate something that clicks with them."
Hamels and hitters
Cole Hamels is scheduled to face hitters in live batting practice Thursday for the first time, although pitching coach Bob McClure would not confirm whether Hamels will throw. After Thursday's game, McClure said he had to check with head athletic trainer Scott Sheridan.
When asked about Hamels' status Wednesday, manager Ryne Sandberg said, "He's doing fine."
Hamels, who was sidelined in the winter by biceps tendinitis, could pitch in a Grapefruit League game next week.
Gonzalez and Tigers
The Phillies will have their first split-squad day Thursday with a home game against Masahiro Tanaka and the New York Yankees at Bright House Field and a road game against the Detroit Tigers in Lakeland, Fla. They will send Miguel Alfredo Gonzalez on the bus for his second spring appearance.
"There was no strategy there or anything," Sandberg said.
Gonzalez will pitch after David Buchanan. Both faced the Yankees last week, and Detroit is expected to play its regulars.
"That's a good challenge for him," Sandberg said. "And the way Buchanan has been pitching up until now, it'll be a good test for him, also."
Third baseman Cody Asche (bruised hand) pinch-hit and struck out in the ninth inning of a 2-2 tie with Atlanta on Wednesday for his first appearance in three days. He will start Thursday.
