New No. 1 Osaka takes on the mantle
Naomi Osaka celebrates a point during the Australian Open final.
With Andy Murray tearfully announcing his impending retirement, and Roger Federer bundled out by 20-year-old Stefanos Tsitsipas, it was tempting to hope for a changing of the guard in men's tennis at this year's Australian Open.
The men aren't ready for that just yet, with veterans Novak Djokovic and Rafael Nadal meeting for the 53rd time on Sunday to contest the final. The Serb triumphed 6-3 6-2 6-3, winning a record seventh Aussie Open title in one of the most one-sided finals in the season-opening major in years.

But while the men's sport is still waiting for its young guns to step up -- Tsitsipas looked bereft against Nadal in his semifinal, and 24-year-old Frenchman Lucas Pouille barely strung two points together against Djokovic -- Naomi Osaka, the 20-year old Japanese-American who won her long, often grueling final against Petra Kvitova on Saturday, is more than ready to take on the mantle of the player to beat.

Osaka, who beat her idol Serena Williams last summer to win her first major, is the first woman to follow her debut slam with another since Jennifer Capriati in 2001, and the first to win two in a row since Williams in 2015. The win bags her the world No. 1 slot for the first time, and while she still often fails to put away opponents when the opportunity presents itself, her future is undoubtedly bright.
After it was all over Saturday, the 21-year-old admitted that at the trophy presentation she "forgot to smile." But the watching tennis world didn't.
Solskjaer marches on; FA Cup continues to provide upsets
Manchester United's interim manager Ole Gunnar Solskjaer, celebrates after the FA Cup Fourth Round match between his team and Arsenal.
When Ole Gunnar Solskjaer was shown the door at Cardiff City in 2014, it was a sad reckoning for the Manchester United legend. While his football intelligence was never in doubt on the pitch for the Red Devils, that early foray into management in the English game looked to have seriously dented his reputation.
It's a good thing for Man U fans that their club didn't use that spell in Wales as a yardstick for the Norwegian's coaching abilities. He's now won eight straight games in all competitions, and hasn't seen anything besides a 'W' next to his team's name since he took over the toxic mess left behind by Jose Mourinho.
