Although they're off to their best start ever and have the best record in baseball, the San Diego Padres aren't getting a swelled head.

"By no means are we going to get too high. By no means are we thinking we're the best team," Andy Ashby said Thursday after pitching eight scoreless innings in San Diego's 4-1 victory over the Chicago Cubs. "We've just got to go out and keep playing."Ken Caminiti homered for the Padres, who improved to 16-4 and remained unbeaten in seven series this season.

"We're having a good run," manager Bruce Bochy said.

Once again, Caminiti played with pain. The third baseman has a strained back that makes its difficult for him to throw, and he's also been bothered by an ingrown toenail.

"He's got the highest pain threshold of anyone I know," Bochy said. "There are days when you question whether you should put him in the lineup and he goes out and has a great day."

Ashby (3-1) allowed seven hits, struck out four and walked one for the Padres, who took two of three games from the Cubs.

"We've had a couple lackluster efforts on offense the last couple games," Chicago's Mark Grace said. "We've got to pick it up, and when it happens, it's going to be fun. Nobody likes losing when you score one, two runs."

Houston at the New York Mets was postponed by rain.

BREWERS 2, DODGERS 1: Marquis Grissom hit a tiebreaking homer off Hideo Nomo in the seventh inning as Milwaukee beat visiting Los Angeles.

Nomo (1-3), coming off the shortest start of his career, lost despite pitching a three-hitter. Grissom had two hits, including an RBI single.

Grissom broke a 1-1 tie with his second homer of the season, an opposite-field line drive just inside the foul pole in right.

PIRATES 7, GIANTS 0: Francisco Cordova pitched a five-hitter for Pittsburgh's first complete game this season, and Jason Kendall drove in three runs off slumping Shawn Estes.

Kendall had a two-run double in a four-run second inning and added a sacrifice fly as the Pirates won their second in a row after losing seven straight. The Giants went 1-5 on a road trip to Milwaukee and Pittsburgh.

ROCKIES 4, MARLINS 3: Kirt Manwaring hit a two-out, two-run triple in the ninth inning, rallying Colorado to victory at Florida.

Larry Walker drew a leadoff walk from Vic Darensbourg, and reliever Rob Stanifer (0-1) walked Vinny Castilla. Walker advanced on a fly ball, and reliever Felix Heredia struck out Todd Helton. Manwaring, who entered the game in the eighth in a catching change, hit the next pitch over center fielder Mark Kotsay's head.

EXPOS 5, CARDINALS 2: Vladimir Guerrero and Rondell White homered in the third inning for Montreal against St. Louis.

Guerrero homered off Cliff Politte (2-1) with one out and White hit another solo shot one out later to give Montreal a 3-0 lead. Guerrero went 3-for-4 with two RBIs.

Ron Gant homered in his third straight game for the visiting Cardinals, a two-run shot in the fourth that cut the Expos' lead to 3-2.

PHILLIES 6, REDS 3: Scott Rolen hit a three-run homer in the eighth inning to lift Philadelphia over Cincinnati.

The crowd of 10,445 was the smallest to see the Phillies at Veterans Stadium since Sept. 9, 1992.

The Phillies won their first series against Cincinnati at home since April 1994, taking two of three. The Reds had won 17 of their past 20 games in Philadelphia.

BRAVES 3, DIAMONDBACKS 1: Tom Glavine improved to 3-0 and Andres Galarraga snapped an 0-for-11 slump with a 415-foot homer for Atlanta.

Glavine, who leads the majors with a 1.00 ERA, pitched seven strong innings to help the Braves win their third straight and eighth in nine games. He allowed one run on six hits, walked three and struck out five.

Kerry Ligtenberg pitched the eighth, and Mark Wohlers struck out the side in the ninth for his sixth save in six chances.

Glavine gave up his first earned run in 21 innings when Matt Williams doubled and scored on Travis Lee's single in the sixth inning to pull visiting Arizona to a 2-1 deficit. Atlanta made it 3-1 in the bottom of the sixth when Galarraga hit his eighth homer of the season, off Willie Blair (0-4).

AMERICAN LEAGUE

INDIANS 5, WHITE SOX 4: Wil Cordero is back, but the Chicago White Sox still have a ways to go.

Cordero homered on the first pitch he saw in a White Sox uniform, but pinch-hitter Jeff Branson hit a two-run triple in the eighth inning in Cleveland's win.

Cordero returned to the majors after pleading guilty to beating his wife. He wasted no time showing what he can add to this lineup behind Albert Belle and Frank Thomas, hitting Jaret Wright's first pitch in the second inning onto the left-field patio.

Still, the White Sox dropped to 7-12 and 51/2 games behind AL Central-leading Cleveland.

Heading into the eighth, the Indians had stranded nine runners - seven by cleanup hitter Manny Ramirez. Branson, a contact hitter, ended the drought.

Batting for Shawon Dunston with runners on first and third in the eighth, he drove in his first runs of the season with a liner off the right-field wall on a 3-2 pitch from Bill Simas.

DEVIL RAYS 12, RANGERS 5: Tampa Bay became the winningest expansion team in April as Mike Kelly homered twice and Jason Johnson earned his first major league victory.

The Devil Rays improved to 11-8, topping the expansion record of 10 victories in the opening month by the 1977 Toronto Blue Jays and 1993 Florida Marlins. Tampa Bay still has seven games left in April.

Johnson (1-0), making his first big league start and his initial Tampa Bay appearance, blanked the Rangers on three singles until leaving in the sixth.

Bobby Smith homered, doubled twice and drove in three runs for Tampa Bay. Ivan Rodriguez and Lee Stevens homered for the Rangers.
