After years of traveling all over the world from big-time tennis tournament to big-time tennis tournament, Glenn Weiner felt it was time for a change.
Except for his three weeks here with the Springfield Lasers -- including tonight's home match against Philadelphia -- he says he has all but retired from the pro circuit as a player.
Instead, the 32-year-old native of South Africa has found a new calling -- as a coach.
Which will take him, well, all over the world, from big-time tennis tournament to big-time tennis tournament.
So much for mixing things up, huh?
"I stumbled into (coaching) a little bit," Weiner said. "I wasn't sure that I was going to stop playing, but I was hurting (he has recovered from wrist and groin injuries) and they offered me a good job."
"They" would be IMG and Nick Bollettieri Tennis Academies, for whom Weiner has worked as an instructor.
Last December, he became the sole coach for Kei Nishikori, an 18-year-old player from Japan considered a rising star on the ATP Tour.
Under Weiner's tutelage, Nishikori won his first ATP title in February, defeating American James Blake in the finals of the Delray Beach International Tennis Championships.
He became the first Japanese ATP singles winner since 1992, and the youngest to win an ATP title since Lleyton Hewitt won as a 16-year-old in 1998.
Nishikori is ranked No. 103 in the world in singles. He was in the main draw at Wimbledon but had to retire with an abdominal muscle injury after splitting two sets of his first-round match with Marc Gicquel.
Weiner, who made the trip to Wimbledon, says Nishikori will rest for a few weeks but is expected to play for Japan in the Olympics and also play in the U.S. Open.
"After my time here, I'll go back (to the Bollettieri Academy in Florida) to work with him," Weiner said. "I go everywhere with him.
"But I get to do my own thing these three weeks, which is nice."
Coaching wasn't something Weiner had necessarily planned on getting into, he said, but he felt that with his experience and connections he might have a chance to pursue it.
Weiner's results with Nishikori have been outstanding so far, and he is hopeful that both parties benefit from their time together.
"Hopefully, it's a good learning experience for him and I'm learning as a coach," Weiner said. "I'm just trying to make him a little better, bit by bit."
