 It gets tougher for the Mystics. They host the defending champion Las Vegas Aces tomorrow night before embarking on a four-game road trip. And may they fare as well as the Orioles did hosting baseball's defending champion last night. They laid an 11-2 beatdown on the Texas Rangers to open that three-game set at Camden Yards. And in soccer, the U.S. men's national team on the brink of elimination from the Copa America after last night's 2-1 loss to Panama, defined by Tim Weah's red card in the 18th minute.
