Britain's Cameron Norrie described his first-round victory at the Madrid Open as one of his favourite wins in his career after he overcame illness to defeat Martin Landaluce.
Former British number one Norrie beat the 19-year-old Spaniard 6-7 (4-7) 7-5 6-4 to earn a first ATP main-draw victory since the start of March.
Poor form has seen Norrie, 29, drop to 91st in the world, and for a while on Thursday his struggles looked set to continue.
After losing five games in a row from 3-0 up in the opening set, Norrie fought back from 3-0 down before saving a match point and winning the second.
