Miguel Alfredo Gonzalez will not make his scheduled Grapefruit League debut Thursday due to an illness.

Gonzalez did some light running in Phillies camp on Monday but left the complex early. He'll throw one more side session before debuting against the Yankees on Saturday. The Cuban right-hander has underwhelmed so far in bullpen workouts and seems doubtful to crack the Phillies' Opening Day rotation. He was signed to a three-year, $12 million contract in August.

Jim Salisbury of CSNPhilly.com reports that Miguel Alfredo Gonzalez continues to underwhelm at Phillies camp.

Gonzalez threw his second bullpen session on Friday, but his command was spotty and his stuff didn't impress. Phillies manager Ryne Sandberg continues to say they are exercising patience with the Cuban import, but it's starting to look highly unlikely that he'll be included in the Opening Day rotation unless he blows everyone away in the spring.

David Murphy of the Philadelphia Daily News writes that Miguel Gonzalez's velocity on Thursday "looked down compared with many of the other pitchers around him who are supposed to have similar arm strength."

Camp just started, so it's tough to make too big a deal out of velocity issues at this point, but it's something worth filing away nonetheless. When asked how he thought Gonzalez looked, Phillies manager Ryne Sandberg said, "I'm interested to see him build arm strength." Gonzalez no longer has a chance at a spot in the rotation following the A.J. Burnett signing.
