BALTIMORE -- Carlos Martinez struck out eight over six sharp innings, and the St. Louis Cardinals hit a season-high five home runs in an 11-2 rout of the struggling Baltimore Orioles on Friday night.
Rookie Paul DeJong homered, singled twice, scored three runs and had three RBIs to help St. Louis snap a three-game skid.
Matt Carpenter and Dexter Fowler connected in succession to cap a four-run sixth inning, Tommy Pham hit a two-run drive in the seventh and Jedd Gyorko added a solo shot in the ninth.
Coming off a four-hit shutout against Philadelphia, Martinez (6-5) gave up one run and four hits. The right-hander has 45 strikeouts over his last five starts.
The Cardinals arrived at Camden Yards having lost 10 of their previous 14 games, but their breakdown was certainly no worse than that of the Orioles, who were 25-16 on May 20 and now stand at 32-34.
Trey Mancini hit his 11th home run for Baltimore, an anticlimactic drive with two outs in the ninth.
Kevin Gausman (3-6) allowed five runs and nine hits over 5 2/3 innings. He was replaced by Gabriel Ynoa, who yielded three home runs.
After a sacrifice fly by Manny Machado got Baltimore to 2-1 in the third, DeJong hit a two-run drive in the fourth.
An RBI single by DeJong, a two-run drive by Carpenter and Fowler's home run made it 8-1 in the sixth.
Carpenter went 2 for 3 and is 17 for 38 (.447) since he moved into the leadoff spot on June 7.
BALTIMORE -- Orioles closer Zach Britton ruptured his right Achilles tendon in offseason training, a significant injury that could cause him to miss part of the 2018 season.
Baltimore executive vice president of baseball operations Dan Duquette on Wednesday confirmed the torn Achilles tendon. It was not immediately clear how long Britton would be out.
In a tweet announcing the injury, the team said Britton was injured Tuesday while training in California and wished him a speedy recovery.
Britton had 15 saves and a 2.89 ERA with the Orioles this past season. In 2016, had a 0.54 ERA and was perfect in save opportunities with a major league-leading 47.
The left-hander, who turns 30 on Friday, is arbitration eligible after making $11.4 million last season. Britton can become a free agent after next season, which made him a strong trade candidate before the injury.
Britton has converted 135 of 145 save opportunities since becoming the Orioles' closer in 2014.
MORE ORIOLES: GAUSMAN CHANGES HIS NUMBER TO HONOR ROY HALLADAY
BALTIMORE -- Orioles pitcher Kevin Gausman will wear No. 34 next season as a tribute to Roy Halladay, who was killed in a plane crash last month.
Gausman announced the switch Thursday on his Twitter account. The right-hander wore No. 39 last year.
Gausman and Halladay are both from Colorado, and the Orioles pitcher said he followed Halladay's career closely and idolized him.
In a post next a photo of his new jersey, Gausman wrote: "Roy gave me the inspiration that I could fulfill even my biggest of dreams -- being a pitcher just like him."
Gausman concluded: "The loss of Roy is tragic and saddening, but I feel honored to have watched everything he achieved."
Halladay died on Nov. 7 when his small plane crashed into the Gulf of Mexico. He played 16 big league seasons, winning the Cy Young Award in each league and being named an All-Star eight times.
