American Emma Navarro, one of four top-10 seeds left in the women's draw, came back from a set down to eliminate defending Wimbledon champion Barbora Krejcikova 2-6, 6-3, 6-4 in the third round Saturday.
Krejcikova faded in the third set, getting her blood pressure checked at the changeover after Navarro broke her to lead 3-2 at No. 1 Court.
Krejcikova ate a banana and drank liquids during the medical check, while Navarro walked to her guest box and spoke to her coach during the break in action.
When play resumed, Krejcikova still appeared to be in distress, often leaning over and placing her hands on her knees between points.
