SEATTLE -- For the second time in a week, Manny Machado hit a grand slam on the West Coast, and the Orioles were on their way to a big win.
Machado's drive was part of an 11-3 win against the Seattle Mariners before 17,973 at Safeco Field Aug. 14.
Eight games into their 10-game trip, the Orioles are 4-4 and are back where they were when they left Baltimore Aug. 6 -- a game below .500. At 59-60, Baltimore is two games out of the second wild-card spot.
"We've got a chance to have a good road trip," manager Buck Showalter said. "They're competing for the same thing we are, and we caught them on a down night."
Machado, who has 23 home runs this season, has five grand slams in the last two seasons. Machado also hit a grand slam Aug. 7 -- the first game of the Orioles' West Coast trip.
The Orioles teed off against Seattle right-hander Yovani Gallardo, who pitched for Baltimore in 2016 and was traded for outfielder Seth Smith in January.
Gallardo allowed a leadoff home run to Tim Beckham, the shortstop's 16th of the season. After going hitless for the first time with the Orioles in his 13th game Aug. 13, Beckham had three hits against Seattle.
In the second, Gallardo threw 50 pitches and gave up six runs. He was charged with eight runs in four-plus innings.
Smith and Trey Mancini also homered, as the Orioles had 16 hits, their fifth straight game with 10 or more hits, equaling a season-high.
Kevin Gausman was the beneficiary of the offense, working seven innings and allowing two runs on six hits.
"These are the teams that we need to beat, so you get a lead like that. I've got to be able to do what I did," Gausman said. "Kind of shut the door."
After Beckham hit the home run, Gausman quickly allowed a run in the first and had second and third with none out but retired the side to keep the game tied at 1.
"I told him when I took him out of the game: 'That's the ballgame. You won the game in the bottom of the first,'" Showalter said.
The Orioles have two more games in Seattle and then return home and don't play a game out of the Eastern time zone for the remainder of the schedule.
"We've had an up-and-down season, and it's been tough, injuries, guys not producing how well they're supposed to," Machado said.
"There've been a lot of obstacles we've had to overcome, so at this point we just got to keep playing baseball, doing what we're doing and try to keep it simple and not think about how many games we have to win. Just think about it day-by-day, win-by-win and out-by-out, and I think if we do that we can surprise some people."
The Orioles, who haven't had a winning month since April, are 8-6 in August.
"I think we're playing our best baseball right now," Gausman said. "I think if you're starting staff can do what we've been doing lately, I think there's no reason why we can't be in the hunt."
NOTES: SS J.J. Hardy (wrist) hasn't been scheduled for a rehab assignment, yet. He'll hit in the cage Aug. 15. "I'm trying to get out there as soon as I can so I can play as many games as I feel like I need to and then get back in time for September. You can't rush it too much," Hardy said. … RHP Dylan Bundy's next start will be either Aug. 22 or 23. … INF Ryan Flaherty and OF Anthony Santander are playing a pair of rehab games for Class-A Frederick. They're scheduled to be activated Aug. 17. … Left-handers Wade Miley (6-9, 5.19) and Andrew Albers (2017 debut) will face off Aug. 15 at 10:10 p.m. ET. … Adam Jones' fifth-inning double moved him ahead of Boog Powell for fifth place on the Orioles' all-time hit list with 1,575.
