He's a decent prospect for the Jays, and might be with the big club full-time in a year or two.
That said, he's nothing to get excited about right now. He's only filling in for a spot start in place of Chacin, who's on the DL, and might be back off the DL in time for his following start.
Not only that, but Taubenheim's start will be at Colorado, where the Jays have never played before. A rookie making his first career start at Coors is a risky proposition, to say the least..
You've got a diamond, You've got nine men
You've got a hat and a bat, And that's not all..
