LONDON, England – Five-time champion Venus Williams got her Wimbledon challenge underway with a hard-fought win over Donna Vekic on the opening Monday.

In a high-quality encounter, Williams held her nerve at the conclusion of both sets to run out a 7-6(3), 6-4 victory.

“The first round is never easy and she played amazing tennis today,” Williams said. “I expect players to feel free and go for it when they play me. In the first set there were some hairy moments but I guess that’s when experience sets in and I had the chance to win the important points.”

Vekic has endured a season to forget, failing to win a WTA main draw match since February. However, if she was short on confidence it did not show against Williams, trading on even terms with the World No.8 for much of their two hours on court.

She had her chances, too, particularly during an opening set, which she served for at 6-5. Perhaps undermined by memories of her recent run, the Croatian saw two sets points slip before Williams pinched it on the tie-break. The second set was just as closely contested, but once again it was the American that finished stronger, a forehand winner bringing her the solitary break in the ninth game.

Williams, who turned 36 a couple of weeks ago and is seeded No.8, is competing at a Grand Slam for a record-equaling 71st time, but still enjoys pitting herself against the new guard: “You got to enjoy the battle because that’s what it is every time you step on the court. You never know what will happen.”

One member of the next generation expected to go far this fortnight is No.9 seed Madison Keys. A champion at both Birmingham and Eastbourne over the past few years, Keys is no stranger to success on grass, and displayed her nous to overpower Laura Siegemund, 6-3, 6-1.

The next challenge will be 2013 semifinalist Kirsten Flipkens, after she brushed aside Nicole Gibbs, 6-3, 6-1. Elsewhere, there were contrasting fortunes for another former semifinalist, Ana Ivanovic, who was bundled out by qualifier Ekaterina Alexandrova.

A few days on from squeaking past World No.446 Harriet Dart in the final round of qualifying, Alexandrova elevated her game to another level, surviving a late wobble to triumph, 6-2, 7-5.
