"Hitting, you just save one good swing," Smith said. "It's the running around the outfield, running around the bases when you don't feel as great. I told them I had a swing today and was able to give them a good one. I made it around, thankfully."
That was just the beginning.
Gonzalez followed by hitting Haren's second pitch to the deep right-field seats.
As if that wasn't enough, Spilborghs hit Haren's first pitch over the left-field wall.
"I can't remember the last time I sat in the same uniform and saw back-to-back-to-back home runs," Rockies manager Jim Tracy said.
It was the seventh time the spectacle occurred in Rockies history and the first time since Jeromy Burnitz, Charles Johnson and Matt Holliday did it April 27, 2004.
"In 2004, I was in Yakima playing for the Diamondbacks in [Class A]," Gonzalez said. "I hurt myself for like two months and didn't even know if I'd be here."
Smith was in college at Ole Miss, and Spilborghs was in Class A the last time three straight Rockies homered.
On top of hitting his third homer of the season, Spilborghs, who started in place of Smith, went 3-for-4 with two RBIs and two runs against Haren. His performance Thursday boosted his career batting average to .433 (13-for-30) against the three-time All-Star.
"I've always just kind of seen him well and my approach has just kind of always been the same," Spilborghs said. "It helps when I have guys at second base, then I can really just try and stay inside him."
The Rockies, winners of five straight, have homered in a season-best nine consecutive games.
"It was cool," said shortstop Troy Tulowitzki, who also homered Thursday. "Those guys took great swings. Hopefully, there's more to come."
