INDIAN WELLS, California - Three-times Grand Slam champion Stan Wawrinka lost 7-6(3) 4-6 6-2 to Tomas Machac in the Indian Wells first round on Thursday as the Swiss player continues to struggle.

Wawrinka, 38, reached a career high of world number three a decade ago with his aggressive style of play but was unable to match 23-year-old Czech Machac's level in the deciding set and his signature one-handed backhand sail wide on match point.
