CHICAGO — Cade Horton‘s first MLB start brought him the whole nine yards of what pitching in a Cubs uniform can be.

A hot, windy day at Wrigley Field, coupled with the White Sox in the other dugout, conjured up an atmosphere unlike much else.

For Horton, picking up the win in the Cubs’ 13-3 rout of their South Side rivals was an experience to remember.

“It was awesome,” Horton said. “I loved how the fans were in it all game. It was a super cool environment — way better than the (New York) Mets,” he quipped about his debut outing last week at Citi Field — a tense 6-5 Cubs win in which Horton pitched the second through fifth innings.

Horton went five frames Friday, giving up three earned runs on seven hits. All three runs came courtesy of Miguel Vargas’ two-homer game.

With the wind blowing out, Horton had to make some adjustments with the help of his catcher, Carson Kelly.

“Carson did a great job today. We were on the same page a lot of the game,” Horton said. “He just gave me a lot of confidence to attack with my fastball and keep throwing it.”

Kelly said he and Horton discussed the conditions to prepare the young right-hander for anything.

“We talked about it before the game — that the wind’s going to go crazy,” Kelly said. “I’m really proud of him, how he gave up those runs early and got back in the zone and kept us in that game.”

The zone Horton has been in during his first two outings is a good one. He has yet to issue a walk at the major-league level.

“I think that’s that’s always a good sign,” Cubs manager Craig Counsell said of Horton. “On a day like today, you just want to make the other team earn everything. You pitch like that, and you make them earn it.”

Horton, who struck out two Friday, attributed his walk-less line to his fearless approach.

“It’s just wanting to attack guys. That’s the main thing,” Horton said. “I’m fine with giving up hits, but putting guys on — that’s when you start to get in trouble.”

After allowing two runs early, Horton received help from his teammates, who posted a six-run second inning that broke the game wide open for the Cubs.

“The run support was huge. Credit to the offense today,” Horton said. “It allowed me to not be as fine in my pitches. I can go up there and attack just knowing I have a lead.”
