Which Grand Slam title did Serena Williams win in 2005 by defeating Lindsay Davenport?

Serena Williams won the Australian Open in 2005 by defeating Lindsay Davenport.

The final in Melbourne was a dramatic three-set contest, with Williams prevailing 2–6, 6–3, 6–0. Davenport entered as the top seed and world No. 1, while Williams was the seventh seed. The victory gave Williams her second Australian Open singles title, following her 2003 triumph.

The championship was especially notable because Williams had been struggling with injuries and inconsistent form during the preceding period. Her 2005 title helped re-establish her as a leading force in women’s tennis. She also became the first unseeded or lower-seeded player to defeat the top seed in an Australian Open women’s final since the tournament’s modern seeding era began.

This title is sometimes confused with Williams’s other Grand Slam victories over Davenport. Williams also defeated Davenport in the 1999 US Open quarterfinals, but that was not a final. In 2005, the decisive championship match took place at the Australian Open, the first major tournament of the calendar year.
