The Dodgers fielded a lineup of potential starters for the team's season-opening series in Sydney, Australia.
Ryu allowed two runs (one earned) on seven hits and struck out three without issuing a walk in 5 1/3 innings. His next start will be the second game in Sydney.
"I need to work on my curveball a little bit. I missed a few of those, but in time, I'm sure I'll get it back," Ryu said through an interpreter. "I hit the 80-pitch count, so I'm happy with that as well."
Rockies starter Jordan Lyles, who is competing for a rotation spot, lasted 4 1/3 innings and struck out two. He was charged with three runs on five hits and walked two.
Trailing 1-0 in the fourth, the Dodgers scored twice off Lyles. Carl Crawford doubled down the right-field line to lead off, then scored on an Adrian Gonzalez single to tie the game.
Gonzalez came around to score on a two-out double into the left-center-field gap by Juan Uribe to give the Dodgers the lead.
The Rockies opened the scoring in a somewhat odd fashion. Matt McBride reached on an infield single, moved to second on another hit and took third on a wild pickoff throw from Ryu that bounced into center field. McBride broke for home on a fly ball to right from Jordan Pacheco but appeared to be thrown out at home plate by the Dodgers' Yasiel Puig.
Puig's laser-beam throw beat McBride home, but Rockies manager Walt Weiss challenged the call. Replays showed Dodgers catcher A.J. Ellis missed the tag on McBride and the out call was reversed.
"It was good to see the system work," Ellis said. "I knew right away that I didn't touch the guy."
The Rockies put runners on the corners in the fifth against Ryu, but Brandon Barnes' flyout ended the inning.
Charlie Blackmon's single drove in Tim Wheeler to tie the game at 3 in the seventh.
A crowd of 13,115 saw the Dodgers off. Los Angeles finished with a cumulative attendance of 114,402 in 12 home dates at Camelback Ranch for an average of 9,534 per game, the highest average attendance since the team relocated Spring Training to Arizona in 2009.
Up next: Left-hander Brett Anderson, acquired from the Athletics during the offseason, has posted a 1.80 ERA with five strikeouts and one walk in his first 10 Cactus League innings, impressing his new team. He'll have another chance Monday, when the Rockies face the Padres at Peoria Sports Complex at 2:05 p.m. MT.
