BALTIMORE -- Dylan Bundy threw a one-hitter for his first career shutout, Manny Machado hit two of Baltimore's four solo homers, and the Orioles extended their winning streak to six games with a 4-0 victory over Seattle on Tuesday night.
Bundy (13-8) allowed just an infield single to Kyle Seager in the fourth inning and set a career high with 12 strikeouts. The right-hander has a 2.00 ERA in August and has struck out 10 or more in three of his last four starts.
Jonathan Schoop and Welington Castillo also went deep for the Orioles, who moved two games over .500 for the first time since June 10.

Baltimore has outscored its opponents 44-17 during the winning streak. The Orioles also moved 1 games ahead of the Mariners in the AL wild-card race. Minnesota currently holds the second wild-card slot.
Schoop collected his 29th homer of the season and 500th career hit with a solo shot in the first off Erasmo Ramirez (5-5).
Schoop's blast moved him ahead of Machado for the team lead, but not for long. Machado hit his 29th homer in the sixth and reached 30 homers for the third consecutive season with his drive in the eighth off Casey Lawrence.
Bundy, who threw 116 pitches, struck out Danny Valencia for the fourth time to finish off his first career complete game.
In his fifth start since being acquired from Tampa Bay on July 28, Ramirez allowed two runs and five hits over six innings.
Castillo led off the seventh with a homer off James Pazos.
The start of the game was delayed 32 minutes because of rain.
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.
