SEATTLE (AP) — Ryan Court drove in three runs in his first big league start, rookie Austin Nola also had three RBIs and the Seattle Mariners beat the Detroit Tigers 8-1 Saturday.

The Mariners have their longest winning streak since April. The Tigers lost their fifth in a row and fell 40 games below .500 — at 30-70, they’ve been held to one or fewer runs 22 times this season.

Nola hit a two-run triple in the fourth inning and the 31-year-old Court, who lined out as a pinch-hitter a day earlier in his debut, had an RBI single for his first hit and a 3-1 lead.

Nola added an RBI double in the four-run seventh inning and Court matched him with a two-run, ground-rule double to make it 8-1.

The Mariners started three rookies in the game with Dylan Moore at shortstop. Court, who played right field and first base, is the 58th player to suit up for the Mariners and the 13th rookie to make his debut with Seattle this year.

Omar Narvaez had four hits for Seattle and Tim Beckham doubled twice, singled and scored two runs.

Marco Gonzales (12-8) is 7-2 in his last nine starts since June 7. He’s given up more than three runs just once in that stretch. He scattered six hits over seven innings.

Tigers starter Tyler Alexander (0-1) struck out nine, but only made it through 4 1/3 innings after giving up eight hits and four runs.

With two starting outfielders injured, the Mariners claimed Keon Broxton off waivers from Baltimore. Broxton was designated for assignment on July 21. He started the season with the New York Mets, playing 34 games before being acquired by Baltimore for international bonus pool money. He’s batting .184 in 71 games.

The Mariners moved reliever Connor Sadzeck (right elbow inflammation) to the 60-day injured list to make room on the roster.

Also, the Pittsburgh Pirates claimed reliever Parker Markel off waivers from the Mariners. He was designated for assignment on July 23.
