In Manager Larry Dierker's return to the dugout, Derek Bell hit a go-ahead, two-run single in the seventh inning as the Astros overcame a six-run deficit to beat the Detroit Tigers, 8-6, last night in Houston.

Dierker collapsed in the dugout on June 13, and two days later had brain surgery to repair malformed blood vessels. Houston went 13-14 under interim manager Matt Galante, the team's bench coach.

Dierker received a standing ovation when he appeared in the dugout. Dierker and his wife Judy got another ovation in the fifth when their picture appeared on an outfield screen.

"It was a wonderful comeback to come back with a comeback win," Dierker said. "That's kind of the way we did it last year."

ATHLETICS 11, GIANTS 9: Olmedo Saenz hit a three-run homer with two outs in the ninth, giving Oakland the victory over cross-bay rival San Francisco.

The A's scored four in the eighth but trailed 9-8 going into the ninth. Tim Raines singled with one out and John Jaha walked. Matt Stairs struck out, but Saenz homered to left-center off Robb Nen (3-3), who blew a save for the fifth time in 26 chances.

San Francisco's Barry Bonds received his 294th intentional walk in the sixth, setting a major league record. He had been tied with Henry Aaron for the career mark.

BRAVES 6, YANKEES 2: Tom Glavine got off a fine start in the second half. Roger Clemens got booed off.

In just the second matchup of reigning Cy Young winners, Glavine pitched Atlanta past Clemens and New York before a restless crowd of 49,087 at Yankee Stadium. The only other time defending Cy Young winners faced each other in the regular season came on Aug. 28, 1989, when Frank Viola led the New York Mets over Orel Hershiser, 1-0, at Dodger Stadium.

Glavine (8-8) left after 6 2/3 innings with a 6-2 lead. Clemens gave up six runs on six hits and five walks in six-plus innings.

The fans booed loudly when Clemens (8-4) was chased during a three-run seventh inning. Asked whether he noticed the booing, Clemens quickly said no. "I'm just going to try to continue to work hard and minimize mistakes," he said.

Javy Lopez, out since June 20 because of an injured right knee, drove in three runs for Atlanta.

INDIANS 2, PIRATES 0: If Cleveland still is seeking a No. 1 starter, it might try looking in its own rotation. Bartolo Colon regularly hit 101 mph on the radar gun during eight shutout innings in Cleveland's win in Pittsburgh.

Colon (8-3), who brought a 5.35 ERA into the game, was superb after winning only once in nine previous starts. He struck out eight and limited the Pirates to three singles in eight innings.

RANGERS 3, DIAMONDBACKS 2: Randy Johnson can't escape his jinx. Mark McLemore's bases-loaded double with two outs in the ninth drove in all three Texas runs, despite a dominating performance by Johnson.

Johnson, who had pitched well his last four starts but got zero runs from his teammates, shut out Texas on six hits over eight innings. Newly acquired closer Matt Mantei replaced him to start the ninth. Mantei (1-3) got the first two outs on a strikeout and a grounder, then became only the second major league pitcher to walk three straight pinch hitters before giving up McLemore's hit.

"I turned an easy save situation into a loss," said Mantei, who was a strike away from ending the game on three of the last four hitters. "Randy pitched his butt off and I couldn't finish it."

PADRES 3, MARINERS 2: The House that Junior Built opened with a Seattle loss, thanks to another blown save by the Mariners' bullpen.

Before a sellout crowd of 44,607 on hand to witness the opener at Safeco Field, Jose Mesa wasted a ninth-inning lead by walking four San Diego batters, then gave up a sacrifice fly by Eric Owens. It was the Mariners' sixth straight loss.

METS 8, DEVIL RAYS 7: In St. Petersburg, Fla., Roger Cedeno's RBI double in the 10th inning won it for New York. Cedeno lined a 1-0 pitch over the head of Tampa Bay center fielder Randy Winn, one out after Benny Agbayani doubled.

RED SOX 6, PHILLIES 4: Host Boston held off Philadelphia in a game featuring five home runs. There were three leadoff homers in the first two innings -- by Philadelphia's Doug Glanville and Boston's Jose Offerman in the first, and Boston's Jason Varitek in the second.

REDS 10, ROCKIES 7: In Cincinnati, Greg Vaughn homered and drove in three runs as the Reds continued to surge by pounding Colorado.

CUBS 9, TWINS 3: In Chicago, Sammy Sosa snapped out of a slump with his major league-leading 33rd homer and a double, and Henry Rodriguez hit a three-run shot against Minnesota.

CARDINALS 3, WHITE SOX 2: Rick Croushore scored from first when Greg Norton threw away a 13th-inning bunt, and St. Louis edged visiting Chicago. Mark McGwire hit his 29th home run for the Cardinals.

MARLINS 8, BLUE JAYS 6: In Toronto, Mike Lowell hit a tiebreaking single in the ninth inning to win it for Florida.

ANGELS 7, DODGERS 6: Mo Vaughn singled home the winning run in the 10th inning, giving Anaheim its fifth victory in six games. The visiting Dodgers had won four in a row.

ROYALS-BREWERS, PPD: Kansas City's game against Milwaukee was postponed after a construction accident Wedmesdau at the Brewers' new Miller Park led to the death of three workers.

CAPTION: In Houston, Astros Manager Larry Dierker signs an autograph in his first game back since suffering a seizure in a June 13 game against the Padres.
