The other big unknown is actually more of a certainty. With Oswalt, the Phillies have between $135.35 million and $146.35 million guaranteed to 16 players next season, depending on how much of the $11 million from the Astros they put toward their payroll this season. They entered 2010 with a payroll around $137 million. While Amaro's budget is likely to increase next season, he acknowledged that the Phillies will be counting on cheaper, homegrown players to fill their remaining nine roster spots. The only traditional high-dollar positions unfilled are rightfield, where Jayson Werth will be a free agent, and a No. 5 starter, where Kyle Kendrick could be arbitration-eligible. Top prospect Domonic Brown, called up on Wednesday, is penciled into rightfield, but it remains to be seen how much money the Phillies can spend on fortifying their bullpen and bench.
