Highs and lows from the French Open's first few days

It took more than three days to finish, but the first round of the French Open is finally complete. And a whole lot happened along the way, from the inspiring to the frustrating. Here's the best, and worst, so far.

Serena Williams played her first Grand Slam match since giving birth to her daughter in September, and she won it in straight sets—in a catsuit, no less.

"I feel like a super hero when I wear it," Williams said.

The three-time French Open champion cracked 13 aces and won 80 percent of her first-serve points to beat Kristyna Pliskova, 7-6 (4), 6-4.

While Williams fared well in her opener, several of the other big names weren't so fortunate. The first round saw the elimination of defending champion Jelena Ostapenko, defending finalist Stan Wawrinka, two-time Slam winner Victoria Azarenka and all-time great Venus Williams, just to name a few.

Attributable to the new withdrawal policy, players way down the pecking order got a chance to gain prize money and experience this year. Eight lucky losers got a second chance in the men's draw. This  group included Argentina's world No. 190 Marco Trungelliti, who drove for 10 hours with his 88-year-old grandmother for the possibility of playing in the first round.

He wound up not only getting into the main draw, but getting a win as well. He beat Bernard Tomic in four sets to make Round 2, before losing on Wednesday.

One of the last things any fan wants to see during a Grand Slam is rain, especially when there is no roof in sight. One can only hope for sunshine going forward, but there looks to be more rain in the forecast as the tournament progresses.

There was some concern before the Slam started that some players, especially Rafael Nadal, would be able to cruise through the draw. But so far that hasn't been the case. Nadal had to fight hard against Simone Bolelli in his opener, playing his first tiebreaker in Paris since 2013. Elina Svitolina, David Goffin, Maria Sharapova and Simona Halep were all tested, too.
