STAN Wawrinka became the first major casualty of the men’s draw at Wimbledon as he lost in the second round to Juan Martin del Potro.

Wawrinka is the fourth seed and came up against a player who is comfortably better than his world ranking of 165.

The 2009 US Open champion, del Potro has been beset by injuries almost ever since that victory and this was his first Wimbledon since 2013.

On form here, though, the Argentinian is a high-ranking seed in all but name and it was Wawrinka’s misfortune to run into him at the last-64 stage, del Potro winning 3-6, 6-3, 7-6 (7-2), 6-3.

“My hands are shaking ­— I feel alive,” del Potro said afterwards.

“I was so happy on court. It is like my second or third career in my short life. I was really sad at home for the last two years.

“I like to share moments with the crowd. They support me on every point and that is why I keep fighting in every set.”

Number 10 seed Tomas Berdych rattled through his second-round match with Benjamin Becker in an hour and 24 minutes, winning 6-4, 6-1, 6-2, with 13 aces and 43 winners.
