A new month meant the same old power from the Toronto Blue Jays.
Brad Fullmer hit a two-run, tiebreaking shot in the sixth inning -- one of four Toronto homers -- and right-hander Chris Carpenter stayed perfect in six career decisions against Chicago as the Blue Jays beat the White Sox in Chicago.
Toronto led the AL with 43 homers in April and picked it back up on the first day of May. Raul Mondesi, Jose Cruz Jr., and Alex Gonzalez also homered off Kip Wells (2-3).
Carpenter (3-3) won his third straight game this season and ran his career record to 4-0 in Comiskey Park. He gave up five hits, including back-to-back homers on successive pitches to Chris Singleton and Carlos Lee in the fifth, and was replaced after issuing two-out walks to Ray Durham and Jose Valentin in the eighth.
Billy Koch then retired Frank Thomas on a roller to third and pitched the ninth for his sixth save. Koch allowed an RBI groundout to Lee in the ninth.
Mondesi led off the sixth with his fifth homer to tie the game at 2. After Carlos Delgado doubled, Fullmer followed with a two-run shot to right, his sixth, to give the Jays a 4-2 lead. Gonzalez hit his first of the season in the seventh to expand the lead to three.
Cruz homered to give the Blue Jays a 1-0 lead in the third before Singleton and Lee, connected in the fifth.
ATHLETICS 7, ROYALS 5:
Terrence Long drove in four runs and Omar Olivares won for the first time since April 5 as the Oakland Athletics beat the Kansas City Royals for their fourth straight win.
Long, recalled from Triple-A Sacramento on April 24, hit a bases-loaded triple in the second inning and an RBI single that capped a three-run in the eighth. The rookie is batting .290 ( 9-for-31), getting hits in six of seven games.
Oakland trailed 5-4 in the eighth, then loaded the bases with one out against Dan Reichert (1-1) and tied the score on Eric Chavez's infield grounder. Pinch-hitter Olmedo Saenz singled in the go-ahead run and Long followed with another RBI single.
Olivares (2-3), whose other win was against Detroit, allowed five runs and eight hits in seven innings. Doug Jones pitched a one-hit eighth and Jason Isringhausen got three straight outs for his fifth save in five chances.
ASTROS 5, BREWERS 0:
Octavio Dotel (1-2) combined with three relievers on a two-hitter, and Mitch Meluskey went 2-for-4 with a two-run homer and three RBI.
Steve Woodard (0-4) dropped to 0-7 in 16 starts since he beat Kansas City last July 16, allowing three runs, nine hits and four walks in 5 2/3 innings innings.
Houston took three of four in the series, blanking the Brewers twice. Milwaukee has been shut out three times this season.
Dotel allowed a one-out single to Tyler Houston in the fifth and left after the inning because of a sore left hip. Mike Maddux gave up Houston's two-out double in the seventh, and Jay Powell and Billy Wagner each followed with a hitless inning.
ROCKIES 15, EXPOS 8:
Todd Helton became the sixth player in Colorado history to hit three homers in a game, going 4-for-5 with five RBI to lead the Rockies over the Montreal Expos.
Larry Walker and Jeffrey Hammonds also connected for the Rockies, and the teams tied a Coors Field record with 10 homers. The Rockies and New York Mets scored 61 runs in three games over the weekend.
Helton, who has nine career multihomer games in three seasons -- four against Montreal -- hit a pair of two-run homers off starter Dustin Hermanson (3-2) and added a solo shot off Anthony Telford in the seventh.
He joined Kevin Elster of the Los Angles Dodgers and Alex Rodriguez of the Mariners in hitting three homers in a game this season.
Chris Widger hit two solo homers and Peter Bergeron added his first career home run for the Expos, who lost for only the fourth time in 12 games.
