NEW YORK -- Two well-defined American streaks collided Monday night in the first round of the US Open.
Madison Keys, 21, who has the look of a future No. 1 player, has reached the second week of the past five Grand Slams. In 2015, Keys sailed into the semifinals of the Australian Open, losing to Serena Williams.
Meanwhile, 26-year-old Alison Riske -- ranked No. 60 among WTA players -- had lost her first-round match in the past eight majors.
Seems like an easy call, right?
Well, for the longest time, this one was a fair fight.
