The Astros were the only winless team left in the majors and came close to tying the team’s 0-9 opening in 1983.
Norris (1-0) struck out a career-high nine and held the Cardinals without an earned run for five innings. He also got his first career RBI to put the Astros ahead for good.
Jeff Keppinger had two hits and his first three RBIs of the season, matching his career best. Michael Bourn contributed his fourth straight two-hit game and scored from first on Keppinger’s hit-and-run double in the third off Kyle Lohse (0-1).
Nationals 7 Phillies 5: In Philadelphia, pinch-hitter Ryan Zimmerman hit a go-ahead, two-run homer off Danys Baez in the eighth inning and the Washington Nationals rallied past the Philadelphia Phillies.
Adam Dunn also connected for the Nationals, who stopped Philadelphia’s five-game winning streak.
Chase Utley hit his fourth homer in three games and Shane Victorino also went deep for Philadelphia. The Phillies received their 2009 NL championship rings before the game.
Tyler Clippard (2-0) pitched 1 1-3 innings of scoreless relief to earn the win. Matt Capps got the last five outs for his fourth save in four tries.
Trailing 4-2 in the eighth, the Nationals scored three off Baez (0-1) to take the lead.
Mets 5 Rockies 0: In Denver, Mike Pelfrey pitched seven solid innings and hit an RBI single, helping the New York Mets beat the Colorado Rockies to avert a series sweep.
Pelfrey (2-0) allowed five hits, struck out six and walked none as the Mets ended a four-game skid. Only two of the Rockies’ hits got out of the infield.
Pedro Feliciano and Francisco Rodriguez each pitched a hitless inning to finish New York’s first shutout of the season.
Jorge De La Rosa (1-1), whose 17 wins since June 1 are the most in the majors, struggled with his control while allowing five runs and eight hits over six innings. He walked five and threw two wild pitches that figured in a pair of runs.
Brewers 8 Cubs 6: In Chicago, Rickie Weeks hit a tiebreaking single in the seventh inning and Trevor Hoffman protected a late lead, giving the Milwaukee Brewers a win over the Chicago Cubs.
Ryan Braun and Casey McGehee each homered and drove in three runs as the Brewers avoided a three-game sweep.
On an unusual 80-degree April day at Wrigley Field with the wind blowing out at 18 mph, the Brewers overcame home runs by Derrek Lee, Marlon Byrd and Aramis Ramirez.
Hoffman, who had blown his two previous save opportunities, allowed one run in the ninth for his third save this season and record 594th of his career.
Chris Narveson (1-0) got the win and Jeff Samardzija (0-1) took the loss. Marlins 10 Reds 2: In Miami, Jorge Cantu extended his major league season-opening record to 10 games with a hit and an RBI, Josh Johnson struck out 10 in six innings of easy work and the Florida Marlins salvaged a four-game series split by beating the Cincinnati Reds.
Cody Ross was 3 for 5 with two doubles and three RBIs for the Marlins, who led 8-1 after five innings. Cameron Maybin hit his first home run of the season for Florida, part of a three-hit night.
Before Cantu’s run to open 2010, the previous major league record for having at least one hit and one RBI in every game to start the season had been eight, set back in 1921 by George Kelly of the New York Giants, a year after RBIs became an official statistic.
Johnson (1-1) allowed five hits in six innings and missed tying a career high by one strikeout. Aaron Harang (0-2) got into big trouble in the fifth, thanks in part to a wild pitch.
Braves 6 Padres 2: In San Diego, Jason Heyward drove in two runs on a pair of doubles and Martin Prado homered to help the Atlanta Braves win and take two of three from the San Diego Padres.
Leading 3-2, the Braves gave themselves a cushion with three straight run-scoring hits with two outs in the eighth. Yunel Escobar singled, Heyward doubled into the left-center gap and pinch-hitter Eric Hinske singled.
Tim Hudson (1-0) held the Padres scoreless on three hits through five innings before the Padres broke through in the sixth. Prado’s homer came off Mat Latos (0-1).
Dodgers 6 Diamondbacks 5, 10 innings: In Los Angeles, Stephen Drew’s crazy throw over the first-base dugout gave Los Angeles the tying run with two outs in the ninth, then Andre Ethier got another winning hit in the 10th.
Arizona closer Chad Qualls blew a save for the second straight night, with help from the shortstop’s gaffe. Drew charged Casey Blake’s slow bouncer and the ball appeared to slip, flying from his hand and into the seats.
Manny Ramirez hit a two-out RBI single to make it 5-4 and came home on the error.
Ethier drove a pitch from Blaine Boyer (1-1) over Chris Young, who was playing in shallow center with runners on second and third for the 10th winning hit of his career. Six came last season.
Jonathan Broxton (1-0) pitched a perfect 10th.
