Joachim ‘Pim-Pim’ Johansson forced to retire at 25

Swedish tennis player Joachim 'Pim-Pim' Johansson, who once reached number nine in the world, announced his retirement on Friday at the age of 25 because of a long-standing shoulder injury.

“I can practice for a few weeks and play an individual tournament but after that my shoulder gets overworked forcing me to rest for a longer period of time,” said the Swede who has been dogged by injury for three years.

“Taking that into account it is hard for me to reach my objectives and for that reason it makes it impossible for me to continue my challenge.”

Johansson’s shoulder problems started at the beginning of 2005 season, with the first of his three surgeries performed in July, 2005.

The 6ft 6in right-hander won three career singles titles and reached the semi-finals of the 2004 US Open, when he beat defending champion Andy Roddick before falling to Lleyton Hewitt.

The following year at the Australian Open, Johansson hit an ATP co-record of 51 aces in his four-set loss to Andre Agassi in the fourth round.
