—It’s obvious from the first point we see in this clip that Puig is seeing the ball extremely well. She’s forced to stretch for a decent wide serve, but she still reaches out and drills the ball back with too much pace for Kerber to handle. Paul Annacone likes to talk about “hitting aggressive shots to conservative targets”; over and over in this match, Puig showed us what that means and why it works.
—Puig never plays it safe, but she also doesn’t take wild risks. She hits the ball early and to specific spots, focuses on depth as much as pace and builds points rather than going for outright winners right away. Even her service motion is more self-assured than normal.
But it’s Puig’s backhand that’s the difference-maker. It may have been the most devastating weapon wielded by any player, in any match, in 2016. She put her backhand returns at Kerber’s feet; moved her from side to side with it; hit winners crosscourt and down the line that left Kerber staring at her coach in disbelief; and came under it for drop-shot winners, just for good measure.
—In that sense, Puig exposed what will likely always be a vulnerability of Kerber’s, even now that she’s No. 1. The German can do a lot of things, but she can’t take the racquet out of her opponent’s hands. If an opponent is determined to attack her, and is connecting the way Puig is here, Kerber can be beaten.
In the past, faced with this kind of onslaught, Kerber might have drowned in a sea of sarcastic anger; and she does give Puig an ironic racquet clap after one of her more spectacular winners. But Kerber also battles back, and the rallies get more intense in the second set. At the end of one of the best of them, Kerber puts a forehand volley into the net and is broken for 4-4. She collapses, and the crowd goes berserk; the match seems to be all but over. But Kerber breaks right back and holds for the second set.
—In the third, though, it’s all Puig again; there’s no stopping her. She runs out to a 5-0 lead, and after going down 0-40 at 5-1, she comes back to hold for the gold. Judging by the clip above, Puig’s level never really drops. She never gets tentative or shows much in the way of nerves. To break for 5-0, she wins a point after hitting a full-stretch volley that lands on the baseline. If Kerber had broken for 5-2, would things have turned around? How much longer could Puig have kept that level up? Fortunately for her, and the citizens of Puerto Rico, we’ll never have to know.
