With Andy Roddick‘s unexpected early departure, much of the star power of this year’s Legg Mason Classic went with him. At the semifinal matches on Saturday, fans had the chance to watch one of the two remaining seeded players eliminate the other, followed by a match between two relative unknowns.

At the afternoon semifinal match, Tommy Haas struggled to make any headway in ending the winning streak of Juan Martín del Potro, losing the first set, 6-2, and allowing the young Argentinian player to blank him at 4-0 in the second before winning a game. The crowd’s support for the German veteran, cheering at every point he made and near-point he did not, was not enough to help him turn the tide. Afterward, Haas again dismissed questions about pain or tightness in his shoulder after a third surgery earlier this year. His shoulder feels fine, he said, but del Potro’s reach and speed were too much for him on the court. That Haas did not even stage any spectacular arguments over judges’ calls is a sign that his heart was just not in it.
