PHILADELPHIA (Ticker) -- After Jim Thome matched a team record, teammate Tim Worrell erased any chance of a victory for the Philadelphia Phillies .

Juan Rivera snapped a tie with an RBI single and pinch hitter Carl Everett added a two-run base hit as the Montreal Expos rallied for four runs off Worrell in the eighth inning and posted a 6-3 win over the Phillies.

With Philadelphia trailing by a run in the fifth, Thome followed a leadoff walk to Bobby Abreu with his major league-leading 27th home run and 15th of June, tying the club record for most in any month. Cy Williams also belted 15 homers in May 1923.

"You don't think about (the record) too much when you lose a game," Thome said.

Despite struggling with his control and creating several jams, starter Paul Abbott was in line for his first win with the Phillies until Worrell entered to start the eighth with Philadelphia clinging to a 3-2 lead.

After retiring the leadoff batter, Worrell (2-3) yielded back-to-back singles by Jose Vidro and Nick Johnson , putting runners at the corners. Tony Batista , who homered in the second inning, lifted a sacrifice fly to center field, tying the game.

Johnson alertly advanced to second on the play and rookie Terrmel Sledge was walked intentionally to bring up Rivera, who lined a 1-2 offering into right for a base hit, scoring Johnson with the go-ahead run.

"Three or four good things happened that set up that inning for us," Montreal manager Frank Robinson said. "Number one, Vidro gets the hit to start the inning. (Secondly), that was a pretty good piece of baserunning (by Johnson). (And) Rivera, just a real big two-strike hit there."

Brian Schneider drew a walk to fill the bases again, and Everett followed with a single to plate two and give Montreal a 6-3 cushion.

"I guess if you want a summary of my inning, (it) was that they played that inning aggressive," Worrell said. "I didn't pitch too aggressive. ... I chalk it up to (I) just didn't have it tonight. I don't feel like I pitched the way I've pitched for the last month."

"We had the game right where we wanted it - (leading) 3-2 with Tim Worrell in the game and (Billy) Wagner (to pitch) in the ninth," Phillies manager Larry Bowa said. "It just didn't work out."

The rally secured the first career win for Joe Horgan (1-0), who needed just one pitch to retire the only batter he faced in the seventh.

"It was nice for me to get my first," Horgan said. "Maybe next time, I get to earn it a little more."

Luis Ayala worked a perfect eighth and Chad Cordero struck out a pair in the ninth for his fifth save.

Vidro, who went 3-for-5, extended his hitting streak to 17 games with a single in the first inning.

"All the extra hitting and working in the cage in the end (helped) to accomplish these things because my average was way down," said Vidro, who has raised his average to .288 after entering June at .229. "For this team to win, I need to be out there swinging the bat good."

Brad Wilkerson also homered for the Expos, who posted their first win at Citizens Bank Park in six attempts. Montreal also won when trailing after seven innings for the first time in 38 opportunities.

Expos starter Zach Day also had control problems, walking a career-high seven while allowing three runs and eight hits in 6 2/3 innings. But Robinson was pleased with the effort.

"He gave me what we needed - a good 6 2/3 innings," he said.
