It's become part of Novak Djokovic's routine now, particularly at Grand Slam tournaments: He shows up and gets asked -- at the start of the event, during the event, after the event or sometimes all three -- whether this will be his final appearance there.

Djokovic offered something of a mix of seemingly trying to quiet any talk about whether he truly is pondering retirement at age 38 while also being realistic about where things stand.

For Novak Djokovic, winning Wimbledon for an eighth time would be his record-extending 25th major. At age 38, the Serbian knows his singles tennis days are numbered. Djokovic touched on retirement earlier this month with the Grand Slam on grass looming and was asked again about the possibility of stepping away prior to his opening-round match in London next week.
