Of the three, only Teaford has Major League experience. In the past three years, he's pitched 45 games (eight starts) for Kansas City with a 3-5 record and a 4.25 ERA. He's also spent time with Omaha in those three seasons.
"All of three of them are getting to the point where they're on the radar up here," manager Ned Yost said. "I like Alexander and Marks, and all three guys could pitch out of the 'pen and be effective for us."
Marks has been primarily a starter in the Minors and had a 6-13 record last year for Omaha. Alexander was a reliever with three different clubs last year, mostly with Double-A Northwest Arkansas, posting a 5.18 ERA in 24 games.
