DENVER -- Aaron Sanchez allowed one run in eight innings and Josh Donaldson homered to lead the Toronto Blue Jays to a 5-3 victory over theColorado Rockies.
Sanchez (8-1) allowed six hits, struck out three and walked two in extending his unbeaten streak to 12 games.
The Blue Jays won their first series ever in Denver and their first overall since June 13-16, against the Philadelphia Phillies.
Roberto Osuna gave up RBI doubles to Mark Reynolds and Daniel Descalso and put the tying run in scoring position with one out in the ninth. He hit Charlie Blackmon to load the bases before he struck out Cristhian Adames to end the game.
Tyler Anderson (0-2) allowed the homer to Donaldson with two outs in the third inning and an RBI single to Troy Tulowitzki two batters later to give Toronto a 3-0 lead.
Junior Lake and Edwin Encarnacion also drove in runs for the Blue Jays. Ryan Goins scored on a wild pitch in the ninth to push the lead to 5-1.
In the seventh, Sanchez allowed a single and two walks to load the bases, but left unscathed after inducing pinch-hitter Ryan Raburn into an inning-ending double play. He followed it with a hitless eighth.
Tulowitzki went 2 for 13 in his first trip back to Colorado since his trade to the Blue Jays. He played in front of a warmly receptive crowd over the three days at Coors Field. The former Rockies All-Star homered Tuesday, in a game that started nearly three hours late because of intense rain and hail and didn't end until 1:12 a.m.
TOP PITCHING PROSPECT CLOSE(equals)
RHP Jeff Hoffman may want to stay near a phone. A call-up could be near.
"I'm not sure when that would be," Rockies manager Walt Weiss said, "but I think he's pretty close."
Hoffman was the Blue Jays' first pick in the 2014 draft before he was shipped to Colorado as part of the trade for Tulowitzki last July.
Hoffman is the Rockies' top pitching prospect and is ranked 47th among all prospects, according to MLB.com.
Blue Jays: Brett Cecil (triceps) will likely be activated off the 15-day DL on Thursday before the Blue Jays' four-game series against the Cleveland Indians.
Rockies: SS Trevor Story (finger) sat out Wednesday. He was hit in the middle finger by a ninth-inning pitch Sunday and re-aggravated it in a late at-bat Tuesday. . 2B DJ LeMahieu (knee) appeared as a defensive replacement Tuesday, but the Rockies chose to give him a couple more days of rest with the team off Thursday. . RHP Adam Ottavino (elbow), rehabbing from Tommy John surgery, pitched a clean inning for Colorado's Triple-A affiliate Albuquerque Isotopes on Tuesday.
Blue Jays: RHP R.A. Dickey (5-8, 4.23 ERA) opens a four-game set against the surging Indians on Thursday. The veteran knuckleballer struggled in his last outing, allowing a season-high four home runs against the Chicago White Sox.
Rockies: LHP Jorge De La Rosa (5-4, 6.47 ERA) will take the mound against theLos Angeles Dodgers on Friday. De La Rosa seems to have found his groove since rejoining the rotation on June 14, allowing just four runs over 17 innings.
