Jameson Taillon will make his highly-anticipated Major League debut on Wednesday, but his stay with the Pittsburgh Pirates may be short-lived.

"This may be a spot start for Jameson. A lot of that decision will be beyond his control," Neal Huntington said.

Taillon has dominated with Triple-A Indianapolis, recording a 2.04 ERA, 61 strikeouts and just six walks in 61 2/3 innings this season.

Injuries prevented the top prospect from pitching the last two seasons.
