DENVER — Pedro Peralta cries every time his son Freddy pitches, and watching him make his major league debut was certain to bring tears.

Young Freddy made sure they were tears of joy.

Peralta took a no-hit bid into the sixth inning of his first big-league start and set a Brewers rookie record with 13 strikeouts in a 7-3 win over the Rockies on Sunday.

It became a memorable Mother’s Day for Pedro, Peralta’s mother, Octavia, and his girlfriend, Maritza, who came to Colorado expecting to watch him pitch professionally for the first time at Triple-A Colorado Springs. But a stomach illness forced Chase Anderson to miss his Saturday start against the Rockies, and Peralta’s start for the Sky Sox was scratched so he could pitch for the Brewers on Sunday.

The news brought more tears for Pedro.

“I know he cries a lot,” Peralta said. “Like (Saturday), when I told him what was going on, he started crying.”

A 21-year-old right-hander who was 5-1 this season at Colorado Springs, Peralta (1-0) didn’t allow a hit until David Dahl hit a sharp single to center with one out in the sixth. Peralta froze Charlie Blackmon on a 92 mph fastball for a called third strike and was replaced by Matt Albers.

As he walked off the mound, the enormity of the moment nearly overcame him.

“I was like, ‘Oh my god, I did it. I’m here,’ ” he said. “I almost started to cry. Almost.”

Peralta walked two in ⁄ innings and left after 98 pitches. He broke the Brewers rookie strikeouts record of 12 shared by Teddy Higuera (1985), Juan Nieves (1986), Cal Eldred (1992) and Steve Woodard (1997).
