Tony Santillan, recalled from Triple-A Louisville on Saturday to make his major league debut while filling in for injured Sonny Gray, fell one out short of qualifying for the win. The 24-year-old right-hander allowed one run on five hits and four walks in 4 2-3 innings, striking out five.

Santillan needed 97 pitches to get 14 outs, leaving with the bases loaded and rain falling. He also hit two batters.

Ryan Hendrix (3-1), the first of five Reds relievers, came in and struck out Dom Nuñez swinging on a ball in the dirt to get credit for the win.

The Rockies stranded 10 runners in the first five innings, twice leaving the bases loaded, on the way to their fourth straight loss and seventh in their last nine.

Catcher Tucker Barnhart helped Santillan escape a second-inning jam, hustling around the plate umpire to make a sliding catch of pitcher Antonio Senzatela’s popped-up bunt near Colorado’s on-deck circle with runners on first and third and one out.

Suárez followed Joey Votto’s RBI single in the second with his 14th homer of the season, a drive that left fielder Raimel Tapia watched sail into the stands after just two steps.

Senzatela (2-7) lasted two batters into the seventh inning, leaving after Shogo Akiyama’s pinch-hit double off the right field wall put runners at second and third. Jesse Winker had a two-run double in the inning.

The Rockies needed just four pitches from Santillan to take a 1-0 lead. Tapia singled on the second pitch, Yonathan Daza hit the next pitch to right for a ground-rule double and Charlie Blackmon delivered a sacrifice fly on his first pitch.

Santillan regrouped to strike out Trevor Story looking and coax Ryan McMahon into an inning-ending flyout.

McMahon added his 15th homer in the seventh.
