Serena Williams is on the longest winning streak of her career.
The top-ranked American beat Carla Suarez Navarro 6-2, 6-0 Friday to reach the Italian Open semifinals and extend her victory run to 22 matches.
Williams had twice won 21 in a row before, although both of those streaks came a decade ago, in 2002 and 2003.
In the other half of the draw, two-time defending champion Maria Sharapova withdrew before her quarterfinal match against seventh-seeded Sara Errani due to illness.
Showing off near-perfect form less than 10 days before the French Open begins on May 26, Williams has dropped only three games in her last two matches. Against the 22nd-ranked Suarez, the American hit winners seemingly at will.
The 15-time Grand Slam champion has also won her previous three tournaments.
Williams will next face either two-time Rome winner Jelena Jankovic or Romanian qualifier Simona Halep.
Williams' only title at the Italian Open came in 2002, when she beat Justine Henin in the final....
