"It was a dream come true," Clevenger said.
Clevenger started against the Padres, part of Quade's "kids' day" movement to give the young players on the roster a start.
When Geovany Soto and Koyie Hill haven't been catching, Clevenger was listening to tips to prepare him for Monday's game.
"They've done a good job with him," Quade said before the game. "He's a bright kid. He's been in all the meetings and he understands [Monday's starter] Casey [Coleman] as well as anybody. Maybe we'll give him a little bit of help, but I'd like to see between the two of them what they've learned from the meetings and how they put it into play."
Clevenger spent most of the season at Double-A Tennessee, where he batted .295 with 27 doubles, three triples, five homers and 39 RBIs. He went 0-for-3, but handled the position well.
"That's a kid who, a few years ago, there were questions about his catching ability," Quade said of Clevenger, drafted as a shortstop but converted to a catcher.
