Finally, the answer he came up with was hilarious."Let me think for a second. Uh, every five is a hundred, so... every five is a hundred, so that’s... I’ve been drinking too much tonight. Every five is a hundred, so... there’s ten fives—I mean... it’s $10,000."The host then asked how he came up with $10,000 answer. Fritz answered:"In the math, I said every five $20 bills is a hundred, so... How many did you ask? You said 50 of them? So there’s ten of them, so... ten of a hundred is a thousand. And I’m an idiot. Alright. Like I said, I’ve been drinking..."Taylor Fritz kicks off hardcourt season positivelyTaylor Fritz, who is the top-seeded American in the Citi DC Open, kicked off his Washington campaign by defeating Aleksandar Vukic 6‑3, 6‑2.
