With Ryan Vogelsong throwing 68 pitches in relief Saturday, Heston - as expected - should make the second start of his career Monday against the Rockies. Heston looked strong in his first major league start, earning a win against the Diamondbacks. He will face a tougher challenge Monday, when he takes on a red-hot Colorado lineup. The start is fortunately at home as opposed to Coors, but it would still be a risky endeavor relying on such an unproved arm against a tough lineup.
