Johanna Konta was unable to capitalise on a fine start as she fell to a second-round loss to third-seed Simona Halep at the Mutua Madrid Open.
The heavy schedule looked like it might well have caught up with the British No 1, who reached the final of the WTA Tour event in Rabat last weekbefore dashing to the Spanish capital and defeating Alison Riske in round one.
But after playing a fine opening set that she came close to winning, Konta fell away dramatically and looked fatigued as she went down 7-5 6-1 to the French Open champion.
