Let's get straight to the point: Madison Keys is crushing the ball this fortnight, and she's hitting it bigger than ever at Australian Open 2022.
The American has powered her way into the semifinals at Melbourne Park, her first trip to a major semifinal in more than three years, and her first at the AO since 2015.
Keys takes a 10-match winning streak into Thursday night's blockbuster semifinal against world No.1 Ash Barty.
And she will be hoping her power is enough to knock the Aussie superstar off the baseline, and out of the tournament.
Barty has been almost impenetrable on serve, and that will need to continue because Keys is returning better than ever.
The former world No.7 is striking forehand returns more than 5km/h faster than she was in 2020, the last time she played at Melbourne Park.
And when facing second serves, Keys is crunching her forehand returns, on average, almost 10km/h faster than two years ago, at 133.1km/h.
When we focus on topspin forehand returns alone, Keys is averaging a strike of 136.2km/h in reply to second serves – the highest speed of the four women's semifinalists at AO 2022.
Interestingly, Keys is returning first serves with her topspin forehand at an average of 127km/h – considerably faster than men's quarterfinalists Matteo Berrettini (112.5km/h) and Jannik Sinner (108.1km/h).
Off the ground, she is averaging the fastest forehand (124km/h) and backhand (117.1km/h) speeds of the remaining semifinalists.
She has also struck 73 forehand winners throughout the fortnight – the most of any female player.
While Barty may have been the most dominant player on serve in the women's draw, Keys has powered a tournament-high 35 aces – and is already up to 86 aces for the season.
Barty, on a nine-match winning streak of her own, is perhaps better than any player at neutralising a big-hitter's weapons.
But she has yet to face a player with the weapons and power of Keys.
Somebody's winning streak will end at Rod Laver Arena on Thursday night – and the other will advance to their first Australian Open final.
