Recap

After spending three weeks on the sidelines with an injury, Nishikori continued his winning return to the court on Wednesday, notching a confident 7-6 (3), 6-2 victory over Lorenzi in one hour, 40 minutes.

The Japanese contender trailed his Italian opponent for a grand total of one game over the course of the entire match, and TennisTV showed Nishikori had the gumption to showcase a little bit of flair:

He wasn't the only one in firing form in front of the Basel crowd on Wednesday, however, as Sock waltzed his way to a 6-3, 6-3 victory against Mannarino, needing only an hour to ease into the second round.

There, Sock will face off against Marcel Granollers, who defeated Henri Laaksonen on Tuesday to advance.

Sock took to Instagram to celebrate a rudimentary triumph:

Zverev kept up the trend of straight-sets wins by preventing Fritz from joining his compatriot in the second round with a 7-6 (3), 6-0 victory, getting the better of his 18-year-old foe with relative ease.

Pella's outing was also easier than expected, as Gasquet retired in the second set of their clash.

Tennis writer Rene Denfeld noted the Frenchman showed some signs of an injury concern:

Verdasco was shown the Swiss Indoors exit by Carreno, who won the last three games of the first set in succession to stage an audacious comeback result.

And del Potro's win over Haase also required no small amount of fortitude, namely in the second set, where he returned from deficits of two games and three games to progress, per Portuguese journalist jose Morgado:

Del Potro will line up against Belgium's David Goffin in the second round, while Carreno will clash against No. 4 seed Marin Cilic, and Zverev will meet Argentina's Pella.

Federico Delbonis also made his way into the Swiss Indoors quarter-finals after he beat Ricardas Berankis 6-7(4), 7-6(3), 6-3, coming back from a set down to edge a tight final fixture of the Wednesday schedule.
