Sara Errani regularly criss-crossed the globe while amassing nearly $13 million in career earnings.

Until this week, her tennis travels never included a stop in Hawaii.

Errani, who owns a career grand slam in doubles and peaked at No. 5 in the singles rankings in 2013, arrived for her first visit to Oahu last Wednesday in advance of the second Hawaii Open in a whirlwind conclusion to the season.

“It’s amazing here, it’s unbelievable,” Errani said, looking toward the ocean from a balcony at the Four Seasons in Ko Olina. “It’s good to have this kind of tournament at the end of the year, so it’s nice to be here and enjoying it.”

Errani spent three weeks playing in China, went home to Italy for 10 days, returned to China for the Taipei OEC Open, then headed to Hawaii for this week’s WTA 125K Series event at Patsy T. Mink Central Oahu Regional Park.

The second Hawaii Open — one of eight WTA 125K events and the only stop in the U.S. — opens today with the qualifying draw. The main draw begins Monday, with the doubles final set for Saturday afternoon and the singles final the next day.

CiCi Bellis weathered a blustery week in Waipio to pick up her first WTA tournament win in the inaugural Hawaii Open. Bellis was voted the WTA newcomer of the year in October, but was a late scratch from the Hawaii Open field due to injury.

Bellis opponent in last year’s final, Shuai Zhang of China, returns as the highest-ranked player in the field at No. 36 in the world.

Veterans such as Zhang and Errani are joined by promising youngsters in the 32-player main draw.

“There’s players people love to see. Some of the younger players, people don’t know,” tournament director Ben Goldsmith said. “But at this time last year, very few people knew who CiCi Bellis was, but now she’s a household name. We’ll find our new rising star here this week.”

Errani, 30, owns nine singles and 26 doubles titles, including the career grand slam with Roberta Vinci. She played in the 2012 French Open singles final and reached No. 1 in doubles that year as well.

“She doesn’t need to play Hawaii. She can get a wild card at any tournament in the world with her résumé. But she chose to come to Hawaii,” Goldsmith said. “There’s a small group of people who have done what she’s done in tennis.”

Errani will concentrate on singles this week as she continues her comeback from a two-month suspension by the International Tennis Federation for an anti-doping rule violation. In a WTA report posted at the time of her suspension in August, Errani attributed the test “to food contaminated by her mother’s medication for breast cancer.”

She’ll compete in a tournament that extended its sponsorship agreement with the Hawaii Tourism Authority for another three years following last year’s inaugural event. Goldsmith also doubled the doubles draw to 16 teams and added television coverage for the tournament.

Tennis Channel is scheduled to televise all of this week’s matches on CORP’s featured court through the singles final. Goldsmith said the tournament has also been picked up by networks in Asia and the Middle East.

In today’s qualifying draw, eight players — including Hawaii Pacific University senior Lena Lutzeier — will play for the last two spots in the main draw. Lutzeier earned a qualifying berth by winning the UTR Honolulu Open on Nov. 5.

The main draw pairings will be revealed tonight, with matches starting Monday. The day sessions start at 10 a.m., with night sessions starting at 6 p.m. The doubles championship is scheduled for 6 p.m. on Saturday. The tournament concludes with the singles final at 2 p.m. Sunday.
