Two Major League Baseball stars had to receive emergency medical treatment on the field after suffering heat-related illnesses on Saturday afternoon.
Cincinnati Reds superstar Elly De La Cruz and Seattle Mariners reliever Trent Thornton both fell foul of extreme weather as temperatures closed in on 100 degrees across the US.
De La Cruz, 23, vomited on the field in the fourth inning of the Reds' loss in St Louis, before trainers rushed to assist him.
Incredibly, he managed to carry on - and even went on to hit a two-run home run in the seventh inning.
'I actually watched him,' Reds manager Terry Francona explained after the game. 'He [De La Cruz] drank a bunch of water. I mean a bunch... and then he went right out and got rid of it.'
Thornton, meanwhile, suffered a 'scary' moment on the mound and had to be helped back to the dugout by trainers.

The Mariners manager, Dan Wilson, later opened up on the 'heat-related illness', explaining to reporters: 'He battled hard. It was a scary moment for sure. But just really glad that he's feeling a little bit better now and should be OK.'
Seattle were playing against the Cubs in Chicago on Saturday afternoon, where temperatures hit 94f at first pitch.
In St Louis, meanwhile, it was 92 degrees during the game, and another game was even worse, with Milwaukee at Minnesota played under an 'excessive heat warning'.
Temperatures are only set to get worse this week, with New York tipping 100f on Tuesday - the day the Mets host the Braves at Citi Field.
