BASEL, Oct 24 (Reuters) - Third seed Stefanos Tsitsipas avoided an upset defeat against Ricardas Berankis when he came from a set down to reach the Swiss Indoors quarter-finals on Thursday.
The Lithuanian, ranked 70th, won the first set in a tiebreak before Tsitsipas took control of his service games to secure the remaining two sets comfortably for a 6-7 (4) 6-2 6-4 win.
Sixth-ranked Tsitsipas faced one break point in the match, and he won 75% of his second-serve points on the way to his 13th quarter-final of the season.
The 21-year-old has recovered well from a poor patch of form in August, reaching the China Open final and the Shanghai Masters semi-finals. (Reporting by Brian Homewood, editing by Ed Osmond)
