After a trying season marred by injury, Andy Murray has parted ways with coach Ivan Lendl.
"Huge thanks to Ivan for all his help and guidance over the years," Murray wrote Friday on Facebook. "We've had a great time together and I wish him all the best."
Thus ends the second stint in Murray and Lendl's partnership. Their first lasted about two-and-a-half years, and ended in March of 2014. Lendl rejoined Murray's coaching team in June of 2016.
Murray has won all three of his Grand Slam titles and both his Olympic gold medals with Lendl in his corner. After Lendl climbed back aboard last year, Murray embarked on the greatest run of his career, winning eight of the final 10 tournaments he played, including Wimbledon, the Rio Olympics, and the World Tour Finals, en route to becoming world No. 1 for the first time.
He was unable to replicate that magic in 2017, as a hip injury rendered him ineffective and ultimately forced him to shut his season down before the US Open. His world ranking has consequently tumbled to No. 16.
Murray's health was a catalyst the first time the pair ended their highly successful working relationship after he underwent back surgery. That time, Lendl opted to walk away, leaving Murray feeling "gutted."
This time, the decision seems to have been a more mutual one.
"I wish Andy well going forward," said Lendl, who will continue to work with USTA Players Development. "We had a great run and a lot of fun."
