Cloyd called up. Could he be here to stay?

The Phillies announced this morning that Cole Hamels will not take the mound at Citizens Bank tonight against the Mets, as originally scheduled. Hamels has a stomach illness.

Pithcing in his place will be 25-year-old righthander Tyler Cloyd.

Since Hamels will almost certainly be plugged back into the rotation in the next few days, Cloyd will be added to the roster (a corresonding move will be made prior to tonight's game) as a fill-in, emergency starter.

But Cloyd (12-1 with a 2.35 ERA in 22 starts at Triple A Lehigh Valley) could do what many a pitcher before him has done - Kyle Kendrick in 2007 comes to mind - and pitch well enough to stick in the rotation.

Vance Worley had another off-kilter start Tuesday night, blowing a 4-1 lead and getting knocked out before completing five innings. The potential sophomore slump he scoffed at in spring training has become very real: he has a 5.80 ERA in his last 11 starts. 

Since Worley has to have loose bodies removed from his elbow after the season anyway, he could be shut down for injury-reasons, as well as ineffectiveness.

Cloyd hasn't slowed down since beginning the season 3-0 with a 1.80 ERA in four starts at Double A Reading.

He's 4-0 with a 2.92 ERA in eight starts at Lehigh following the International League's All-Star break. He was honored as the International League's Most Valuable Pitcher of the Year award this week.

Cloyd will get his first major league opportunity tonight. It could be the first of a monthlong tryout in the big leagues.
