A leadoff triple by Anderson Comas in the bottom of the eighth inning Friday night allowed Great Falls to rally past Grand Junction 9-8 after the Rockies had come back from a 7-3 deficit.
Comas tripled off Jacob Kostyshock (1-1) and scored on Cabrera Weaver's bloop single to right to tie the game at 8-8. Harvin Mendoza got the go-ahead run home for the Voyagers when his hard line drive glanced off the glove of Julio Carreras at second base into right field for a single.
The Rockies (26-23, 7-4) had come back twice, first scoring four runs in the fifth inning to tie the game 7-7 after a rare shaky start by Mitchell Kilkenny, who allowed seven runs on nine hits in his five innings.
He struck out four and his offense got him off the hook by tying the game.
Reese Berberet struck out, but a wild pitch allowed him to reach first, and he ended up on third when catcher Ivan Gonzalez's throw sailed down the right-field line. He scored when Ronaiker Palma grounded out, and three straight singles by Carreras, Cristopher Navarro and Christian Koss loaded the bases.
A throwing error on a pickoff attempt by Karan Patel allowed Navarro to score and Colin Simpson's two-run double to right tied the game at 7-7.
Navarro, who went 4 for 4, scored three runs and drove in two, led off the seventh with a base hit and moved up on a wild pitch.
Brenton Doyle delivered a two-out double to left for an 8-7 lead, but Kostyshock couldn't hold the lead.
Notes: Former GJ Rockies and Colorado Mesa pitcher Reagan Todd has been promoted from Short-A Boise to Low-A Asheville. Todd played in Grand Junction last season after being drafted out of CMU. Pitcher Alex Achtermann has been placed on the temporarily inactive list, but is still on the roster.
