Scott Livingstone knows his role.
"That's my job," Livingstone said. "I pinch-hit most of the time. I try and prepare myself to be ready, and fortunately I was looking for the knuckle-curveball. That's what he threw me. I was lucky enough to get a hit in that situation."
Carl Pavano (2-1) limited the Orioles to four hits in seven innings, allowing the only run on Chris Hoiles' second-inning homer. Montreal, which beat Baltimore 9-4 on Friday night to snap a four-game losing streak, won for the sixth time in Pavano's seven starts.
"I had my fastball and my changeup going and me and (catcher Chris) Widger just worked great tonight," Pavano said. "They're a great fastball-hitting team, we know that. You've got to get ahead of them with quality offspeed pitches and that's what we did."
Ugueth Urbina pitched the ninth for his 19th save.
Widger led off the seventh with a single and advanced to second on Shane Andrews' sacrifice. Livingstone, hitting for Pavano, doubled to right off Mike Mussina (6-5) to give the Expos a 2-1 lead. Livingstone has five hits and four RBIs in 21 pinch-hit at-bats.
Jose Vidro, who was 2-for-4 with two RBIs, then singled home pinch-runner Orlando Cabrera to make it 3-1. Vidro also had an RBI double in the third.
"We don't have big names on this team but we've got a lot of heart," Vidro said. "We play hard every day. We don't have a great record, but we're doing better than what people expect from us and we'll stay together as a team."
Montreal is 19 games behind first-place Atlanta in the NL East.
"We had lots of life," Montreal manager Felipe Alou said. "We beat a great pitcher tonight. Carl Pavano gave us seven strong innings. It was the first time he hit the 100-pitch plateau so we took him out. I know he could have probably pitched another one or two innings, but we've got to go gradually with him."
Pavano retired the last eight batters he faced. He struck out four and walked one. Mussina allowed three runs on nine hits in seven innings. He struck out four and walked two.
"We haven't put up much of a fight the last couple of games," Mussina said. "As a team, we haven't put up much of a fight. One night it's pitching, one night it's offense. We can't put it together and it's happening more and more often."
Notes: The Expos said Saturday that pitcher Marc Valdes will undergo tendon transplant surgery to repair a torn ligament in his right elbow. Valdes was placed on the 15-day disabled list Tuesday after leaving Monday night's gam in Toronto in the sixth inning. ... Expos right fielder Vladimir Guerrero made a nice running catch at the wall on Rich Becker's drive with one out in the first. ... Baltimore's Cal Ripken and Brady Anderson have been teammates since 1988. Only Seattle's Jay Buhner and Edgar Martinez, and Atlanta's John Smoltz and Tom Glavine have played together as long. ... Cabrera, who stayed in the game to play second, made a sensational catch on Mike Bordick's fly to shallow center to end the game, holding on to the ball as he leaped over center fielder Rondell White.
