ST. LOUIS — Bryce Miller threw six scoreless innings, Dylan Moore hit a two-run home run and the Mariners scored three insurance runs in the top of the ninth inning to pull away for a 6-1 victory over the St. Louis Cardinals on Friday night.

At 72-70, the Mariners remain 4.5 games back of the Astros in the AL West.

The Mariners are an MLB-leading 47-4 when scoring at least five runs this season.

Miller scattered just three hits — all singles — with two walks and four strikeouts.

It was his eighth start of the season in which he’s pitched at least six scoreless innings, tying Hisashi Iwakuma (2013) for most six-inning scoreless starts in franchise history.

Miller lowered his season ERA to 3.18.

Randy Arozarena helped the Mariners break a scoreless tie off Cardinals starter Erick Fedde with a bases-loaded sacrifice fly in the fifth inning, scoring Victor Robles.

Moore added with his two-run blast off Cardinals left-hander Matthew Liberatore, turning on an inside fastball and sending a line-drive over the wall in left field.

It was Moore’s 10th homer of the season, first since July 26 at the Chicago White Sox and his eighth on the road.

The Cardinals’ Jordan Walker hit a two-out solo homer off Mariners rookie reliever Troy Taylor in the seventh inning.

In the ninth, Mitch Haniger doubled, Julio Rodriguez hit a bloop single and Cal Raleigh followed with a two-run double to extend the lead to 5-1.

Luke Raley added an RBI single to score Raleigh to make it 6-1.

This is the Mariners’ first visit to Busch Stadium since 2013 and just the club’s fourth trip to St. Louis in franchise history.
