Ross Detwiler knows with specificity the distance from Wentzville, Mo., to Busch Stadium. “It’s 38 miles west,” he said. “I made the drive a couple times series.”

Detwiler grew up in suburban St. Louis, rooting for the Cardinals. Every night, he and his family would watch the Cardinals game together. “It was kind of a family event,” Detwiler said. He still lives in Wentzville, and he stayed at his home this season. Sunday, Detwiler will make his first career start against his hometown team.

“My phone rings a lot more than it ever has, that’s for sure,” Detwiler said. “It’s cool to be able to see all my family. There’s a lot of people coming to the game tomorrow. It’s definitely kind of surreal – the team I grew up watching, and now I get a chance to clinch against them if we don’t do it tonight.”

Detwiler only left five tickers for his start tomorrow. All his friends and old teammates from Missouri State fended for themselves for tickets. Earlier this year, Jordan Zimmermann made his first start at home against the Brewers, and a clan of well-wishers trekked from Auburndale, Wisc., to cheer him. They tailgated in the parking lot, wore special-made T-shirts and acted rowdy. Detwiler said not to expect anything similar tomorrow afternoon.

“I don’t know if you’ve realized, but we’re kind of a laid-back family,” Detwiler said, laughing.
