Kvitova's recovery from the severe injuries to her left hand that she sustained in a home invasion in December is one of the most heartwarming stories of the tournament - but she had only confirmed her participation in the draw on Friday, and there were few indications as to the level of her trademark power and shotmaking.
"It's a pleasure to be here". While I'm sure Kvitova will hit a physical wall at some point due to the lack of matches under her belt, she played well enough to win another match and advance to the third round.
"Thank you very much".
On Sunday, she fell a double break down to trail 5-1 to her Russian opponent who she was facing for the 12th time.
Grigor Dimitrov won his first match in four years at Roland Garros to reach the second round of the clay-court major.
The chances of her playing tennis again, he said, were "very low" for a "multiple of reasons".
Being back on court was the main thing but the competitive juices soon kicked back in.
Kvitova raced into a 3-0 lead and had three break points in the fourth game before Boserup finally got on the scoreboard.
There was certainly nothing wrong with the Czech's signature forehand, which soon had Boserup clawing at the clay in vain. "I mean, I know in the last years I had always up and downs and right now, of course, I'm. down".More news: CBO: Republicans' AHCA Would Leave 23 Million More Uninsured

Kvitova also consulted with a hand specialist in the French city of Grenoble every month and she started practicing with a racket at the end of March.
Kvitova also provided details on the intense rehabilitation process that preceded her "last-minute" decision to try her luck in Paris.
A brief rain delay early in the second set came as a surprise on another baking hot day but it did not disrupt Kvitova's rhythm. As she walked to the net for a handshake, her eyes welled with tears.
"Well", Makarova said when informed of the history made by her victory, "that's unbelievable".
She needed just an hour and 13 minutes to wrap up victory and will play either Bethanie Mattek-Sands or Evgeniya Rodina in round two. "We were thinking about something special for this tournament and that's what we. It's still not 100 percent ready, so we will see how everything goes, but I'm happy that I am able to play again".
"I didn't sleep well the days after, but I wasn't really staying alone", Kvitova said.
