HOUSTON (AP) _ Tony Eusebio hit the first grand slam of his career and Jeff Bagwell hit a two-run homer as the Houston Astros overcame the ejection of pitcher Darryl Kile to beat Montreal 10-2 Friday night.

Kile and manager Terry Collins were ejected in the fourth after Kile hit Roberto Kelly with a pitch. Kelly was the first batter for the Expos after Montreal starter Pedro Martinez hit Luis Gonzalez with a pitch in the third inning.

Eusebio highlighted a seven-run seventh with his first homer of the season, off Reid Cornelius. Craig Biggio hit a two-run double in the inning and another run was forced home when Bryan Eversgerd hit Gonzalez with a pitch.

Eusebio has started only 10 games this season, but leads the Astros with 14 RBIs.

Martinez (3-1) had won eight straight decisions since last July 14. He also had won six in a row on the road.

Martinez, who led the NL with 11 hit batsmen last year, pitched six innings with five strikeouts and two walks. Overall, the Expos had won four straight on the road.

Dave Veres (1-0) replaced Kile and pitched three innings with three strikeouts.

Bagwell, in the throes of a season-long slump, hit a 2-1 pitch from Martinez over the center-field fence in the third inning, giving the Astros a 3-1 lead after Biggio had doubled to center field. It was Bagwell's third homer.

Gonzalez singled, went to third base on Dave Magadan's single and scored on Eusebio's double-play grounder in the second.

Moises Alou led off Montreal's second with a double, went to third on a grounder and, after Mike Lansing walked, scored on a double steal.

After being hit by Kile to open the fourth, Kelly went to third base on Darrin Fletcher's single and scored on a single by Lansing.

Notes Shane Reynolds will pitch for the Astros on Saturday night, one day ahead of schedule. He'll replace Mike Hampton, sidelined with a partial tear of the medial collateral ligament in his left elbow. ... Lansing extended his hitting streak to nine games.
