Hundley led off the bottom of the ninth with his first Rockies homer, to right field off Craig Kimbrel, who recovered for his fifth save.
Rockies lefty starter Tyler Matzek left with a 5-2 lead despite walking a career-high six and giving up four hits -- including a Clint Barmes solo homer -- in the first five innings. But after Jorge De La Rosa lasted just two innings Monday night, the short start left what proved to be too many innings for the Rockies' bullpen.
