In the 13 months since Serena Williams last won a tournament, women’s tennis had become an unpredictable landscape overflowing with parity and lacking the dominant players who make the men’s game so enjoyable to follow.

The No. 1 player in the world still has not won a Grand Slam and each of the year’s first three majors were won by different players.

With the U.S. Open less than a month away the women’s draw once again appears wide open, but Williams might have something to say about that.

The 13-time major champion defeated Marion Bartoli in straight sets on Sunday to capture the Bank of the West Classic title — her first win since Wimbledon 2010 — and announce her return to health just in time for the final Grand Slam event of the year.

Williams missed the majority of the last 12 months following her Wimbledon victory as she dealt with blood clots in her lungs and two foot operations.

She flamed out of Wimbledon in a straight set fourth round loss to Bartoli after missing both the Australian and French Opens, but finally appears fit — which may be a dangerous sign for the rest of the field in Flushing Meadows next month.

Williams won the U.S. Open in 1999, 2002 and 2008 — a year in which she won three of the four majors. Before her victory Sunday, no American woman had won a tournament on home soil since Williams’ 2008 U.S. Open title.

Sunday’s win catapulted Williams nearly 90 places to No. 79 in the world after she tumbled to No. 175 in June. She won’t be a high seed at the U.S. Open, but if she can stay healthy and keep her head about her, she’s got a good a shot as anyone to win it
