"We were fortunate. We got some pitches to hit, and hit them," Thome said.
The Phillies have hit 94 home runs this season, including 27 in their last 15 games, and are tied with the Chicago Cubs for the NL lead.
"We didn't have a whole lot of guys on base but it was one of those games where you have to give Millwood credit," Thome said. "He really pitched a nice game for us."
Millwood (5-5), who was 0-3 in his previous seven starts, pitched 6 1/3 effective innings for his first win since May 11. He allowed two runs and five hits, including Orlando Cabrera's RBI single in the first and Jose Vidro's solo homer in the sixth.
"Millwood pitched a great game. We really needed that," Phillies manager Larry Bowa said.
Billy Wagner pitched a perfect ninth for his 10th save in 12 opportunities.
Montreal's three-game winning streak ended one victory short of its season high. Despite the streak, the Expos have lost eight of 11 and have the worst record in the majors at 23-46.
"We've got to tip our hat to Millwood tonight," Vidro said. "He seemed to battle out there and got himself out of some jams. We were battling out there but we came up short."
Phillies center fielder Ricky Ledee returned to Philadelphia earlier in the day to have hemorrhoid surgery, leaving Bowa with a 23-man roster. Right-hander Elizardo Ramirez was not able to fly to Montreal with the team Monday because of visa problems.
Ledee had been scheduled to make his second straight start in center after Marlon Byrd was sent to the minors Sunday. Ledee aggravated his condition in Tuesday's 5-2 loss to Montreal.
Thome drew the Phillies even at 1 in the second when he drove an 0-2 pitch from Kim over the wall in deep left-center to lead off the inning.
Jimmy Rollins hit a one-out double in the third and, one out later, Bobby Abreu's RBI double put Philadelphia up 2-1.
Lieberthal made it 3-1 on his eighth homer with one out in the fourth.
Bell led off the sixth with his seventh homer to increase the lead to three and Rollins hit an RBI single later in the inning to chase Kim.
"When (Kim) got the ball up, they took advantage of it and hit it," Expos manager Frank Robinson said.
Vidro led off the bottom half with his seventh homer. He extended his hitting streak to 10 games, tying the Expos' season high.
Kim allowed five runs and seven hits in 5 2/3 innings.
- The Phillies have hit 92 homers since April 15.
- CF Jason Michaels replaced Ledee in the lineup and went 1-for-3 with a walk before Doug Glanville replaced him defensively in the eighth.
- Tony Batista, Terrmel Sledge and Cabrera also had 10-game hitting streaks for the Expos this season.
