The little guy on the left, we'll call him William ... he shaved 15 seconds off his baseline time for the 25-meter freestyle.
At his pace of improvement, I think that by 2020, he could give Phelps and Lochte a run for their money.
(He's so stinking cute. I have to resist the temptation to pinch his cute little bum in that tiny bathing suit. Sometimes I fail.)
