"He's been throwing the ball good and we like the lefty matchup against this club over there," manager Ned Yost said.
Yost also set up the rotation for the next few days -- Luis Mendoza on Friday night at Minnesota; Jonathan Sanchez and Luke Hochevar, in that order, in the day-night doubleheader on Saturday against the Twins and Bruce Chen in the series finale on Sunday.
That puts Teaford in line to start next Monday night's series opener at Toronto, but Yost will need a starter on Tuesday night against the Blue Jays. The skipper said that could be Vin Mazzaro or someone called up from the Minors.
For now, Mendoza will stay in the rotation with Mazzaro working in long relief.
Does Teaford have potential as a Major League starter?
"I think he does," Yost said. "He's made great strides the last couple years in his career. He started at Double-A a couple of years ago to make a name for himself in our organization. The thing I like about him is he's got three pretty good pitches he throws for strikes and he competes really well."
