Jelena Jankovic won in straight sets despite needing an injury timeout early in her second-round match against Jelena Dokic at the U.S. Open.

The 11{+t}{+h}-seeded Serb won 6-3, 6-4 in one hour, 21 minutes on Thursday. A trainer also worked on her lower back after she won the first set.

Jankovic hasn’t advanced past the third round at Flushing Meadows since 2008, when she lost to Serena Williams in her only Grand Slam final.

The 73{+r}{+d}-ranked Dokic withdrew from three tournaments after Wimbledon with a hamstring injury. The Australian had 15 double-faults in nine service games Thursday, getting broken six times. Jankovic was broken four times.
