LOS ANGELES -- Trayce Thompson hit a game-ending homer in the ninth inning to give the Los Angeles Dodgers a 4-3 win over the Colorado Rockies on Tuesday night in the home debut for teenage prospect Julio Urias.
The 19-year-old Urias struck out seven over four innings. The Mexican left-hander allowed three hits and one run and was removed after 86 pitches with his workload being strictly monitored in just his third career start. It was by far his best so far in the majors.
Kenley Jansen (2-1) got the win after pitching a scoreless ninth.
Thompson hit a two-out blast in the ninth off Carlos Estevez (1-3) to give the Dodgers the win.
Justin Turner hit a three-run homer in the first to give the Dodgers an early lead but the Rockies tied it 3-3 in the seventh.
With runners on first and second and one out in the first, Urias got Carlos Gonzalez swinging through a high fastball to earn a loud roar of approval from the crowd. When he followed with a strikeout of Trevor Story to end the inning, the fans rose to their feet.
The Dodgers gave Urias a lead in the bottom of the first. After Chase Utley and Corey Seager led off with back-to-back walks, Turner sent a 2-0 fastball from Eddie Butler deep into the left-field bleachers for a 3-0 lead.
From there, Urias blossomed. He retired eight his next 10 batters, including five via strikeout, to depart with a 3-1 lead. An RBI double by Nolan Arenado in the third was his only blemish.
Urias' 86 pitches were the most he's thrown this season in 11 starts between the Triple-A and the majors.
The Rockies battled back to tie it against the bullpen. Daniel Descalso led off the seventh with a pinch-hit home run off Joe Blanton, and Gonzalez tied it with a two-out RBI single off Pedro Baez that deflected off second baseman Utley's glove.
That's where the score remained until the ninth, when Thompson lined Estevez's second pitch to send everybody home.
Rockies: OF Charlie Blackmon (rest) did not start but entered as a pinch-hitter in the eighth. He struck out to end his consecutive on-base streak at 32 games.
Dodgers: LHP Brett Anderson (herniated disc surgery) threw for the second straight day from 75 feet on flat ground. It is Anderson's first time throwing back-to-back days since going on the 60-day DL on April 4.
Rockies: LHP Chris Rusin (1-4, 4.62) is winless since moving into the starting rotation on April 30. He has a 6.00 ERA in six starts this season compared to a 1.72 ERA in five relief appearances.
Dodgers: RHP Kenta Maeda (5-3, 2.84) aims to win his third straight start after allowing only one earned run in his last 11 1/3 innings.
