DENVER -- Trevor Story and Charlie Blackmon combined for an inning for the ages in the fourth frame Friday night, running the home run gamut from a grand slam by Story to Blackmon's inside-the-park hustling homer, fueling a six-run outburst to pace the Rockies to a 6-5 win over the Giants.
The Rockies, who are 11-6 atop the National League West, were the first NL team to accomplish the grand slam/inside-the-park tandem in the same inning since the New York Giants accomplished the feat against the Brooklyn Dodgers in 1950, when Don Mueller hit the slam at the Polo Grounds and Hank Thompson legged out the inside-the-park homer. According to Stats, the only other team to do it since was the 2011 Red Sox, with Conor Jackson slamming the Orioles and Jacoby Ellsbury notching the inside-the-park four-bagger in Fenway Park.
Facing Johnny Cueto, a notorious Rockies killer who was 7-0 with a 1.47 ERA over his last eight starts against Colorado, Carlos Gonzalez, Mark Reynolds and Gerardo Parra hit successive singles to load the bases for Story. Story delivered his first career slam on a 1-0 fastball from Cueto.
"The first three guys jumped him early, and Trevor did, too," manager Bud Black said. "Didn't try to do too much with it. I liked the swing on the grand slam for sure."
Story's shot was his 30th career homer, but just his third to right field, per Statcast™ -- with two of the three coming off Cueto. It was the first grand slam allowed by Cueto in his career.
"It feels great, especially to take the lead right there," Story said. "Cueto's tough. He messes with the hitters a lot. It's always going to be a tough day against him. You just have to battle."
There was a steady rain as the inning proceeded, with Tony Wolters singling to left and Tyler Chatwood sacrificing him to second to set the stage for the 11th Rockies inside-the-park home run at Coors Field in the park's 22-plus seasons.

Blackmon thought his line drive was destined to be the inning's final out, but Giants right fielder Hunter Pence lost the ball in the lights.
"There were a lot of balls in the lights I had to battle through," Pence said.
Blackmon thought he hit it hard but straight at Pence and was not optimistic off the bat.
"I was probably doing more watching than running at that point," Blackmon said. "Instead of lining up the base looking for my turn, I was watching to see what was going to happen."
Once the ball darted past Pence and bounced toward the right-field wall, Blackmon was all in and heading for home with the first inside-the-park homer he could remember ever even trying for.
"As soon as it got by him I was like, 'I have to be running to score,'" Blackmon said. "If he stops me, I'll stop, but my goal was to score. There was never any doubt in my mind once I saw it get by him. There was no me letting up and then turning it on."
In a close play, Buster Posey took a relay throw on the first-base side of the dish and Blackmon slid home safely with what would prove to be the game-winning run.
