Get out your rally caps: Only two Americans are left in the U.S. Open’s men’s bracket after John Isner was defeated by Mikhail Youzhny, the 12th seed. In a sluggish performance, Isner made several mistakes: he had 61 unforced errors and his serve was broken four times. Isner lost 6-4, 6-7 (7), 7-6 (5), 6-4 in 3 hours and 18 minutes—a match far shorter than the record-breaking marathon contest at Wimbledon earlier this year. Mardy Fish and Sam Querry have advanced to the fourth round.
