Giolito was cruising along through four innings Tuesday before having his MLB debut ended by a long rain delay, allowing just one hit and two walks with one strikeout against the Mets.
Neither Giolito nor Mets starter Matt Harvey returned after the 83-minute delay, which left the elite prospect ineligible to win due to pitching less than five innings despite leaving with the lead. The plan was only to have the 21-year-old up with the big club until Stephen Strasburg (back) returns, but he may have earned himself a more extended look with a strong debut. If Strasburg doesn't return soon, Giolito could once again find himself on the mound Sunday against the Reds.
