Before Saturday's game, third baseman Cody Asche offered more information about the meeting.
"It was really beneficial," Asche said "In my opinion it kind of shifted the mentality from 'What I am doing wrong' to 'What I can do to help out the lineup and team,' and I think it was necessary and has paid off."
In the five straight wins, the Phillies scored 31 runs while batting .361 (13 for 36) with runners in scoring position.
Domonic Brown was in the posted lineup Saturday but was pulled because of illness.
"A little bit of a fever and some other things going on," manager Ryne Sandberg said.
Brown entered the game as a pinch-hitter and singled to open the seventh inning. He was replaced by pinch- runner Tony Gwynn Jr.
Grady Sizemore, slated to start in center, moved to left but stayed in the leadoff spot. Ben Revere played center and batted eighth.
Nationals righthander Jordan Zimmermann, who left Friday's game after just 31/3 innings with a cramp in his right biceps, had an MRI exam Saturday. The team was awaiting the results.
"He said he was feeling OK, but he was a little sore in his biceps," manager Matt Williams said.
In 2009 Zimmermann underwent Tommy John surgery.
Zimmermann, the only Nationals all-star representative, won't be active for the game and was replaced Saturday by Miami Marlins righthander Henderson Alvarez.
