Dodgers lose to Colorado, 5-4, in 10 innings

KEY MOMENT: Matt Kemp led off the eighth inning with a triple. Andre Ethier, Justin Turner and Tim Federowicz failed to drive him in and break the 4-4 stalemate, as each of them grounded out with the Rockies playing their infield in. “You know it’s an opportunity you let get away,” Manager Don Mattingly said. The Dodgers paid for the blown opportunity in the 10th inning, when Ethier failed to run down Clint Barmes’ drive to the center-field wall and allowed Justin Morneau to score from first base.

AT THE PLATE: Federowicz gave the Dodgers a temporary 4-3 lead in the seventh inning, when he hit a three-run home run. The home run was the first of the season for the backup catcher, who was batting .098 before the at-bat. Ethier, Kemp and Turner each had two hits.

ON THE MOUND: Zack Greinke pitched seven innings and was charged with four runs (three earned) and 11 hits. He struck out six and walked one. Brandon League and J.P. Howell each pitched a scoreless inning of relief. Chris Perez gave up the game-deciding triple to Barmes in the 10th inning and was saddled with the loss.

ON THE MEND: Chad Billingsley is scheduled to start a minor league rehabilitation assignment Sunday with Class-A Rancho Cucamonga, which hosts Bakersfield at LoanMart Field. Billingsley, who is more than 13 months removed from reconstructive elbow surgery, will throw 30 pitches.

OUCH: Assistant hitting coach John Valentin was struck near his left eye by a ball lined by Ethier in an indoor batting cage. Valentin never lost consciousness, but was taken to a nearby hospital to be examined. The tests revealed Valentin didn’t sustain any fractures or damage to his eye. He will be able to travel with the Dodgers to Cincinnati on Sunday evening.

UP NEXT: Clayton Kershaw (4-2, 3.32 earned-run average) will face the Rockies and Jorge De La Rosa (6-4, 3.68) at Coors Field at 1 p.m. PDT. On the air: TV: SportsNet LA. Radio: 570, 1020 (Spanish).
