DENVER — Ezequiel Tovar and Ryan McMahon each hit an RBI single in the bottom of the 10th inning to lift the Colorado Rockies over the Seattle Mariners 2-1 in the first game of a doubleheader Sunday.
The victory snapped a season-worst six-game losing streak for the Rockies (5-16), who entered the day with the worst record in the National League and the worst 20-game start in franchise history.
McMahon's game-ending single sent home Charlie Blackmon for the fifth walk-off RBI of his career.
Seattle broke the scoreless deadlock in the top of the 10th, when J.P. Crawford's RBI single brought home automatic runner Jorge Polanco.
Justin Lawrence (1-1) earned the win. Andrés Muñoz (1-2) took the loss.
With two outs and the bases empty in the bottom of the ninth, Jacob Stallings hit a drive to deep left field that was initially ruled a double. But after a replay review, it was determined the ball deflected off the glove of a fan reaching over the wall, interfering with the outstretched arm of Seattle left fielder Jonatan Clase. As a result, Stallings was ruled out and the game went to extra innings.
Tovar had three hits for the Rockies, including his RBI single that tied it 1-all in the 10th.
The teams spent much of the afternoon failing to capitalize on excellent scoring opportunities. Through the first seven innings, Seattle and Colorado had combined to leave 18 runners on base. They were 1 of 18 with runners in scoring position.
Colorado starter Cal Quantrill gave up three hits while striking out four across six scoreless innings. He was matched for much of his outing by Seattle starter George Kirby, who struck out seven and walked one in five shutout innings.
The Mariners entered on a tear at the plate, scoring 24 runs during their four-game win streak. Julio Rodríguez had two hits for Seattle, his fourth straight multi-hit game.
The doubleheader was scheduled to make up Friday's postponement that was caused by bad weather.
TRAINER'S ROOM
