The Mets aren’t promoting prospect Zack Wheeler for a spot start because the organization would feel pressure to extend his stint in the big leagues, says ESPN New York’s Adam Rubin:
Essentially, team brass internally resolved, New York couldn’t handle a spot start from Wheeler and return to Triple-A.
If the outing was too successful filling in for Niese, the pressure would have been overwhelming to keep Wheeler in the major league rotation. So the organization decided to bypass the potential agita and instead give Collin McHugh the assignment.
The 23-year-old Wheeler, rated the #11 overall prospect by Baseball America entering the season, has a 4.13 ERA in 52.1 innings. The Mets snagged Wheeler from the Giants in the Carlos Beltran trade in July 2011.
Mets manager Terry Collins said, “If Zack comes, we hope that he stays here for the rest of his time.”
