Monfils, on the other hand, has been very much alive for this entire year so far. Each week, the 38-year-old seems to break another age-related record. In January, he became the oldest man since 1990 to win a title; this week, he became the oldest to reach the round of 16 at a Masters 1000.

Befitting a tennis player of his age, though, he hasn’t done it the easy way. Monfils won his first match 6-4 in the third, and his last two 7-6 in the third. He’ll be on court at noon on Tuesday, after staying to watch his wife, Elina Svitolina, play late into the evening on Monday.
