Ramón Laureano and Chad Pinder had two-run singles during Oakland’s big fifth inning, and the Athletics thumped the Seattle Mariners 11-1 on Monday night.

Oakland scored eight times in the fifth inning, with all the runs coming with two outs. The A’s gave starter Frankie Montas plenty of run support and finished off a successful first road trip by taking three of four from Seattle.

Laureano’s single knocked out Seattle starter Justus Sheffield, who had been excellent through the first four innings. Seattle gave its young lefty a chance to escape the bases-loaded jam, but Laureano slapped a single through the right side of the infield to score Khris Davis and Stephen Piscotty.

Seattle rookie Kyle Lewis had his 10-game hitting streak snapped, going 0-for-4 with a pair of strikeouts. He was the first rookie to hit safety in the first 10 games of a season since Delmon Young in 2007.

NO RELIEF

Oakland sent 14 batters to the plate in the fifth and eventually left the bases loaded after Marcus Semien flied out to end the inning. Semien made a pair of outs in the inning.

Laureano’s single knocked out Seattle starter Justus Sheffield, who had been excellent through the first four innings. Seattle gave its young lefty a chance to escape the bases-loaded jam, but Laureano slapped a single through the right side of the infield to score Khris Davis and Stephen Piscotty.

That was the last batter for Sheffield (0-2), but the A’s were just getting started against reliever Bryan Shaw. Shaw gave up five runs on four hits and a pair of walks. Pinder’s two-run single was the big blow, as Davis added an RBI infield single and Piscotty doubled to score another.

The 14 batters were the most in one inning for Oakland since Sept. 12, 2018, against Baltimore, when the A’s sent 15 to the plate and scored 10 times.

Davis hit his first home run of the season in the seventh inning on an 0-2 pitch from Zac Grotz.

Montas (1-1) cruised through seven innings, giving up four hits and striking out nine. Seattle’s only run came on Kyle Seager’s two-out double in the third inning. Montas has allowed two earned runs or less in all three starts.

GIMMIE 10

NO RELIEF

Shaw was signed right before the start of the season after he was released by Colorado, but he’s been ineffective with Seattle. In his past three appearances for Seattle, Shaw has given up a combined 10 earned runs in 2 1/3 innings.

TRAINER’S ROOM

Mariners: Seattle manager Scott Servais was unsure if RHP Kendall Graveman would be able to make his next start due to a neck issue. Graveman threw 4 2/3 innings on Sunday, but was bothered by the neck problem. Graveman was being seen by team physicians on Monday.

UP NEXT

Athletics: LHP Jesús Luzardo (0-0, 1.35) will make his long-awaited debut in the A’s rotation when they open up a three-game series against Texas on Tuesday. Just shy of his 23rd birthday, Luzardo will be the youngest starter for the A’s since Brett Anderson in 2010.
