MONTREAL (Ticker) -- Atlanta starter Russ Ortiz continued his domination of the Montreal Expos this season and kept the Braves headed in the right direction in the process.

Ortiz posted his first shutout of the season and won for the fifth time in as many decisions against Montreal as the Braves ran their winning streak to five games with a 9-0 triumph over the Expos.

The 30-year-old Ortiz (14-7) was perfect through the first five innings before surrendering a leadoff single to Einar Diaz in the sixth inning. He scattered three hits, walked three and struck out five while improving to 8-1 in his last nine decisions.

"Russ was very good," Atlanta manager Bobby Cox said. "I though he might throw a no-hitter tonight the way he was pounding strikes. He had his great changeup going tonight."

"I think he (Ortiz) had good concentration and all his pitches were working for him," Montreal third baseman Tony Batista said. "He threw all his pitches at the right time and put them in the right spot."

Ortiz threw 108 pitches while posting the third shutout and ninth complete game of his career.

"I felt like the way I was throwing, I could finish the game and that was my main focus," Ortiz said. "If the shutout was there obviously thats a great thing, but my whole objective was to finish the game." Chipper Jones had an RBI double in the first inning and Rafael Furcal added a run-scoring hit in the second before scoring on a throwing error to give Atlanta a 3-0 lead.

Montreal starter John Patterson (3-4) walked Jones and J.D. Drew to start the third inning and hit Johnny Estrada with a pitch to load the bases before leaving the game. Andruw Jones greeted reliever Joe Horgan by hitting his first pitch over the left field wall for his second grand slam of the season - and third of his career.

"I just went looking for a pitch to drive and get a sacrifice fly," Andruw Jones said. "I hit it on the sweet spot of the bat and the ball went out."

Ortiz, who has a 1.13 ERA against the Expos in 2004, added a run-scoring double to cap the five-run uprising and rookie Adam LaRoche had three hits, including a solo homer in the fifth.

Atlanta (80-54) is a season-best 26 games over .500 and has the second best record in the National League.

"Everything is going the way we want it to go," Andruw Jones said. "We're just playing good baseball. We're doing all the little things and when guys make mistakes we take advantage."

Patterson allowed six runs - five earned - and three hits. He walked four and struck out four for the Expos, who fell to 4-7 on their season-long 13-game homestand.

"We just didn't pitch well," Montreal manager Frank Robinson said. "We didn't give ourselves a chance and he (Ortiz) wouldn't let us up after he got those runs early. We were never in the ballgame."
