MELBOURNE, Australia - American Brian Baker's hopes of a fairytale run at the Australian Open were ended in the cruellest of fashions on Wednesday when he was taken off court in a wheelchair after suffering a serious knee injury.
The 27-year-old, who returned in 2012 after seven injury-plagued years off the professional circuit, had won the first set of his second round match against compatriot Sam Querrey when he suffered the injury.
"I didn't see what happened," Querrey told reporters. "I hit a ball, and then he hit a ball long. I was looking at the ballkids to grab balls for my serve, and then I looked back and he was on the ground.
"And then just asking him, he said he kind of just felt his knee almost buckle and kind of heard like a pop or a snap. He didn't know if it was bones or a tear, but he couldn't straighten it, couldn't walk.
Australian Open (Jan. 14-27)
Tennis.com: Players besides Serena and Djokovic who could win.
Top-ranked Djokovic cruises
Novak Djokovic's campaign for a hat-trick of Australian Open titles shifted up a gear on Wednesday, as he demolished American Ryan Harrison 6-1 6-2 6-3 to charge into the third round.
The steely-eyed Serb warmed up with a workmanlike performance in his opener against Frenchman Paul-Henri Mathieu, but was at his devastating best in a 91-minute rout of the 62nd-ranked Harrison.
Bullied on the baseline and broken early in each set, the 20-year-old American scrambled hard to make a contest under the lights at Rod Laver Arena, but surrendered the match when his opponent ripped a searing forehand down the line.
Djokovic will continue his bid for a sixth grand slam title, and fourth at Melbourne Park against Czech veteran Radek Stepanek.
No. 24 seed Janowicz survives after on-court tantrum
Poland's Jerzy Janowicz could not afford to come to the Australian Open last year but on Wednesday he made a real mark on the grand slam with a spectacular tantrum followed by a brilliant comeback from two sets down.
The 24th seed exploded with rage over a line call in the tiebreak at the end of the 79-minute first set against Somdev Devvarman, roaring his displeasure, hitting the umpire's chair with his racket and throwing his water bottle across court.
At one stage, the 22-year-old collapsed to his knees in frustration with his forehead touching the playing surface on court eight.
"I was really worried about his voice," said Indian Devvarman. "He was really yelling at the top of his lungs and I said, 'Dude, calm down'."
Devvarman took the tiebreak 12-10 to win the set and, at the changeover, Janowicz again argued his case with Croatian umpire Marija Cicak before making the point more forcefully with his racket.
Janowicz regained his composure and was back on his knees in celebration 161 minutes later after a 6-7 3-6 6-1 6-0 7-5 victory that secured him a third round tie against Spanish 10th seed Nicolas Almagro.
"The umpires, they're making so many mistakes ... this was the moment when I went nuts, otherwise the rest of the match I was pretty calm," said Janowicz, who reached the final of the Paris Masters last November.
"Sometimes it happens like this. You can't control your emotions all the time. This was a really big point for me. We played this set for more than an hour and 10 minutes, so this was a really important point for me."
The nation grieved for those hurt, killed and affected by the Boston Marathon bombings. After one of the suspects was caught on Friday — following a day-long lockdown and manhunt — sports returned to Boston over the weekend.
Nos. 4, 5 seeds Ferrer, Berdych advance
With defending champion Novak Djokovic not playing until the last match on Rod Laver Arena and the two other members of the men's 'Big Four' not back on court until Thursday, there was a somewhat flat feeling to the start of day.
Radwanska was followed on Rod Laver Arena by men's fifth seed Tomas Berdych, who wrapped up a 6-2 6-2 6-4 hammering of Frenchman Guillaume Rufin with his eighth ace after exactly two hours.
David Ferrer, seeded fourth in the absence of Nadal, was playing out on Margaret Court Arena and required 38 minutes longer to dispatch dogged American lucky loser Tim Smyczek 6-0 7-5 4-6 6-3.
Berdych is the likely quarter-final opponent for Djokovic, while Ferrer is seeded to play the Serbian world number one in the semi-finals.
Japan's Kei Nishikori said he had brushed off the knee injury that forced him to withdraw from the Kooyong warm-up after his 7-6 6-4 6-1 victory over Argentina's Carlos Berlocq on court three.
"It's getting better," the 16th seed said. "And I didn't feel any pain today. Just the hot conditions bothered me a little, but otherwise fine."
Serena Williams enters the French Open with the rest of the draw fading fast in her rearview mirror. Can anyone stand in her way?
