Lleyton Hewitt's Australian Open farewell tour has officially ended amid more drama in the stands at the tournament during his third-round loss in the men's doubles at Margaret Court Arena on Sunday. 
Yet another medical emergency in the crowd forced a lengthy delay in the match after the fifth game in the second set when the mother of Hewitt's doubles partner, Sam Groth, fell down the stairs, requiring attention from paramedics.
Groth appeared quite concerned throughout the delay, and had a towel covering the bottom half of his face for the most part.
It was the fourth such incident to occur in the crowd at this year's tournament and comes less than 24 hours after Ana Ivanovic's coach Nigel Sears, also the father-in-law of Andy Murray, collapsed during Ivanovic's third-round match against Madison Keys.
There have been other incidents in the stands in the first week at the Open, including at another of Ivanovic's matches, as well as Bernard Tomic's clash with Denis Istomin.
The all-Australian wildcard pairing of Hewitt and Groth were no match for ninth seeds Vasek Pospisil (Canada) and Jack Sock (US), going down 6-4, 6-2 in 73 minutes. The result officially brought down the curtain on Hewitt's storied 20-year professional tennis career which saw him claim the 2001 US Open and 2002 Wimbledon titles, the 2000 US Open men's doubles crown and the mantle as the world's No.1 player for 80 weeks between 2001-2003.
The Australian legend received one last standing ovation from a Melbourne Park crowd at the end of the match before heading down the tunnel for the very last time.
Little separated the pairings in the first set, with the first eight games going the way of the serve, but Pospisil and Sock achieved a break in the ninth game to take a 5-4 lead before clinching the first set in the next game.
The second set, however, was a different story, with the North Americans kicking off proceedings with a double-break to race to a 4-0 lead and had little trouble thereafter in achieving a convincing straight-sets victory.
Pospisil and Sock ended up converting three of eight break points while Hewitt and Groth failed to bring up a single break-point opportunity.
