Diego Schwartzman earned his 31st victory of the season on Monday as he began the wrapup week of the Indian Wells Masters with a 5-7, 6-4, 6-0 defeat of British No. 1 Dan Evans
The Argentine pocket rocket, seeded 11th, moved into the fourth round at the Californian desert event after losing the first set despite holding a 5-2 lead.
Evans won five straight games to take the opener and went up a break in the second before his nerve failed.
Schwartzman reversed the momentum in the second and third sets to advance in just under two and a half hours, breaking his opponent six times from a dozen chances.
The Brit came into the match having dumped former US Open finalist Kei NIshikori in the previous round.
“I played a poor game at 4-3 in the second set,” Evans said, “I lost my focus and he got pretty hot.
“The match just got away from me, Overall it’s disappointing.
“I was playing good tennis up until 4-3, but I blew that game pretty badly. This is a tough one to take.”
Resurgent Andy Murray and Cam Norrie – both playing on Tuesday – remain in contention for Britain.
Evans had been seeking his 23rd win of the season after winning the only ATP-level title of his career during the first week of the season in January.
Schwartzman backed up his defeat of Evans in the Cincinnati first round two months ago.
