Leo Rivas' tie-breaking, two-run single in the ninth inning propelled the Seattle Mariners to an 11-9 victory over the host St. Louis Cardinals on Saturday afternoon.

Julio Rodriguez, Will Wilson and Cole Young homered for the Mariners, who posted their third straight victory and sent the Cardinals to their third loss in a row.

For St. Louis, Nathan Church hit two home runs and JJ Wetherholt, Ivan Herrera and Pedro Pages also went deep.

Mariners reliever Matt Brash (2-0) earned the victory and Andres Munoz worked the ninth for his fifth save.

Cardinals closer Riley O'Brien (3-1) allowed two runs and four hits in one inning in taking the loss.

J.P. Crawford reached on a bunt single with one out in the ninth, Mitch Garver walked, and Young was hit by a pitch to load the bases. Rivas lined the next pitch up the middle for two RBIs to break a 9-9 deadlock.

Seattle had tied the game in the eighth. Garver and Young led off with singles and advanced on Rivas' sacrifice bunt. The Mariners called on Connor Joe to pinch hit, and the Cardinals countered with O'Brien. Joe lined a two-run single to right to make it 9-9.

The Mariners took a 2-0 lead in the first inning. Cal Raleigh singled, and Rodriguez followed with a blast into the third deck in left field.

The Cardinals tied it in the bottom of the frame as Wetherholt lined the second pitch over the wall in right field and Herrera hit the next out to left-center.

Seattle regained the lead in the second as Garver led off with an infield single and, an out later, Wilson went deep to left. It was the first career homer for Wilson, who was making his Mariners debut at third base with former Cardinal Brendan Donovan on the 10-day injured list (left groin strain).

Church homered to right-center with one out in the bottom of the second to pull the Cardinals to 4-3.

St. Louis took the lead with four runs in the third. Jordan Walker and Nolan Gorman singled to left, and Masyn Winn hit a run-scoring single to right. Church's sacrifice fly to center scored Gorman with the go-ahead run. Pages followed with a two-run shot just inside the left-field foul pole to make it 7-4.

The Mariners tied the score with single runs in the fourth, fifth and sixth.

Young led off the fourth with a homer to right.

In the fifth, Rodriguez singled and stole second. He advanced to third on Josh Naylor's groundout and scored on Randy Arozarena's sacrifice fly.

Church robbed Garver of a home run with a leaping catch at the left-field wall leading off the sixth. Young followed with a double and tied it at 7-all on pinch hitter Dominic Canzone's single up the middle.

The Cardinals regained the lead in the seventh as Winn singled with one out and Church went deep to right-center.
