No. 2-ranked Carlos Alcaraz was upset by Nicolás Jarry of Chile 7-6 (2), 6-3 in the semifinals of the Argentina Open on Saturday. Jarry, after the biggest win of his career, will face home crowd favorite Facundo Díaz Acosta in the final on Sunday. Alcaraz was the defending champion but hasn't looked as sharp and aggressive this week as he was a year ago.
