With the third-place Florida Marlins coming to town for a three-day, four-game series, the Phillies will not alter their rotation. An off day on Monday allows them to do that.
So Cole Hamels will pitch Tuesday with Kyle Kendrick and Roy Halladay pitching in the doubleheader. Halladay will pitch on regular rest; Kendrick has an extra day of rest after only throwing 44 pitches in his last outing. That leaves Cliff Lee on regular rest for Thursday in the series finale.
Roy Oswalt would start the first Interleague game in Seattle on Friday and then the Phillies would have to either pitch Hamels on short rest or use a spot starter. Pitching coach Rich Dubee would not say what his plans are, but it's hard to believe they would throw Hamels on short rest in the middle of June. Vance Worley has pitched well at triple A and this could be the best time for him to return; by then he will have accumulated three starts for the IronPigs.
Adding a pitcher like Worley for the spot start would be feasible. David Herndon, who is on the Allentown express, could be optioned to free up the roster spot.
