Canada's Felix Auger-Aliassime suffered more heartbreak on the ATP Tour as he lost his eighth straight final on Sunday, going down to Croatia's Marin Cilic in straight sets at Stuttgart's grass-court tournament. Cilic, 32, the 2014 US Open champion, won the 19th title of his career with a 7-6 (7/2), 6-3 victory in Sunday's final. The Croat, who is ranked 47 in the world, did not drop a set all week and struck seven aces in the final to claim victory in one hour, 50 minutes. Auger-Aliassime, 20, also lost the 2019 final in Stuttgart and all eight of his defeats in tour finals have come over the last two years. ryj/nr
