Heaney was knocked around in his second start for Triple-A Salt Lake on Wednesday allowing seven runs (four earned) on six hits with a walk and a strikeout in two-thirds of an inning. Heaney's bad start may have come at the worst possible time for the 23-year-old, as Hector Santiago threw seven innings of one-run ball against the Rangers on Wednesday. Garrett Richards (knee) could return as early as Sunday against the Astros, and while nothing has been announced regarding who will get the No. 5 spot in the rotation, Santiago's strong showing could potentially be enough to keep Heaney in the minors for a while longer.
