Celtics@Lakers

9 p.m. [Chs. 2, 7]

Actually, you'll need a few TV sets or a quick finger on the TV remote or maybe, just TiVo. The Lakers try to even their series against the Celtics, who hold a 2-1 edge. But at 6 p.m. on MASN, the Orioles close out a series against the Red Sox. And on ESPN, beginning at 5 p.m., there's the first round of the U.S. Open with Tiger Woods making his return to competition after knee surgery.
