Lincoln native Jack Sock advanced to the second round of the French Open when No. 21 seed Nicolas Almagro of Spain retired with a left foot injury in the first set Tuesday trailing 5-0.
Sock won 20 of 27 points played, ripped seven winners and took advantage of 10 unforced errors from his hobbled opponent during their 21 minutes on court.
This is the second straight year the 21-year-old Sock has advanced to the second round in Paris. He will play either former NCAA champion Steve Johnson or 19-year-old French qualifier Laurent Lokoli in the next round. Johnson led Lokoli 3-1 in the fifth set of their first round match on Tuesday when it was suspended by darkness.
The Roland-Garros singles draw has opened up for Sock, currently ranked No. 75 in the world. No seeds remain in his section leading to the fourth round after No. 16 seed Tommy Haas of Germany (who eliminated Sock in the second round last year) also retired in his first-round match Tuesday.
If Sock would get to the fourth round, his opponent could be world No. 1 and defending champion Rafael Nadal.
