Nolan Arenado hit his NL-leading 39th home run in the 16th inning, and the Colorado Rockies capitalized on a throwing error by rookie shortstop Corey Seager to score three runs in the fourth en route to a 5-4 victory over the Los Angeles Dodgers on Tuesday night.
Despite their fifth loss in 21 games, the Dodgers' magic number for clinching the NL West shrunk to 11 by virtue of San Francisco's 9-8 loss to Cincinnati.
Mat Latos (4-10) made his first career relief appearance, striking out Carlos Gonzalez before Arrenado drove the right-hander's next pitch into the pavilion seats just to the right of center field.
David Hale (4-5) pitched one inning for the victory and Gonzalez Germen, the Rockies' 13th pitcher of the game, got three outs for the save.
Justin Morneau raced all the way to third with his first triple of the season with one out in the 11th after center fielder Chris Heisey got turned around and leaped for the ball on the rain-slicked warning track before falling down. DJ LeMahieu then singled against former Rockies right-hander Juan Nicasio to drive in pinch-runner Ben Paulsen.
But Heisey drove in the tying run with an infield hit to third baseman Arenado, who charged the dribbler with the infield in and couldn't get a grip on the wet ball as rookie Scott Schebler raced home. Rockies closer John Axford was charged with his sixth blown save in 29 chances.
Colorado starter Chris Rusin was charged with three runs and five hits, departing in the seventh with a 3-1 lead, no outs and runners at first and second. The left-hander has only two victories in his previous 13 starts overall, both of them complete games at Coors Field.
Jimmy Rollins, who didn't start for the eighth straight game because of a hand injury, pinch-ran at first base after Rusin gave up a double to Adrian Gonzalez and a walk to A.J. Ellis. A walk to Seager loaded the bases before Heisey hit a sacrifice fly and pinch-hitter Austin Barnes tied it with a bloop single to left for his first major league RBI.
Dodgers lefty Brett Anderson was charged with three runs - two earned - and seven hits in seven innings without walking a batter. He struck out seven, including Gonzalez all three times he faced him. Anderson's first two pitches of the game resulted in bunt singles by Charlie Blackmon and Jose Reyes.
The Rockies grabbed a 3-1 lead in the fourth, parlaying three consecutive singles and Seager's throwing error at shortstop into three runs. Seager, who came in batting .432 since his promotion on Sept. 3, was making his eighth straight start at short in place of Rollins, a four-time Gold Glove winner.
LeMahieu followed inning-opening hits by Arenado and Morneau with a grounder to deep shortstop, which was scored a hit after Seager threw to third base for an attempted force before Justin Turner could get back to the bag.
The ball sailed behind the plate, allowing Arenado to score. Morneau and LeMahieu came home on consecutive groundouts by Corey Dickerson and Dustin Garneu.
Justin Ruggiano led off the Dodgers' first with a double, advanced on a groundout by Chase Utley and scored on Turner's hard-hit single to shortstop off Reyes' glove with the infield playing in.
