NEWPORT: Andy Murray overcame a set deficit to advance to the Hall of Fame Open quarterfinals.
Murray was broken twice by Australia's Max Purcell on his way to winning the first set, and he was broken once more at the beginning of the second.
However, the 35-year-old Briton won the following six games to force a final.
The Scotsman rode that wave to a 4-6 6-2 6-1 triumph over world no. 202, but he was still hobbling severely at the finish line.
The three-time Grand Slam champion appeared to sustain an injury in the second set, but if healthy, he will now compete on Thursday against Kazakhstan's Alexander Bublik, ranked 42, for a spot in the semi-finals.
