Stan Wawrinka announced today that he has added former Wimbledon champion Richard Krajicek to his coaching team for the grass season.

“As I’m always looking to improve on court, I would like to take this opportunity to announce as of immediately that I have added Richard Krajicek to my existing coaching staff to help during the grass court season for the next 4 weeks,” Wawrinka posted on Facebook. “Magnus, Yannick and I are really excited about the new addition to our team – adding a former Wimbledon Champion can only further my knowledge and understanding of the grass. It’s a real privilege and honour to add such a champion to my corner.”

Krajicek won Wimbledon in 1996 beating MaliVai Washington in the final. Wawrinka has made the quarterfinals at Wimbledon the last two years. It’s the only Slam he has yet to make the semifinals at.

Last month Milos Raonic got the ball rolling landing John McEnroe on his team for the grass season. Now Wawrinka joins with the 44-year-old Krajicek who was known for having one of the best serves in the game in the late 90s.

The 31-year-old Wawrinka is currently ranked No. 5. He has three titles on the season but is 0-2 vs Top 10 players.
