PARIS (AP) — U.S. Open runner-upTaylor Fritzlost in the first round of theFrench Openas the tournament's No. 4 seed on Monday, eliminated 7-5, 3-6, 6-3, 6-1 by 66th-ranked Daniel Altmaier of Germany. Altmaier broke Fritz's big serve five times at Court Simonne-Mathieu and ended the Californian's 15-match Grand Slam winning streak against players ranked outside the top 50. Fritz's exit followed another by a top-10 American: No. 9 Emma Navarro was bounced from the women's bracket earlier Monday. In September, Fritz lost the U.S. Open trophy to Jannik Sinner, becoming thefirst U.S. man to reach a major finalsince Andy Roddick in 2009. In Paris, Fritz was the highest-seeded American man at the French Open since Roddick was No. 3 in 2007. While hard courts are Fritz's preferred surface, he did have a run to the second week on the red clay of Roland-Garros a year ago, making it into the fourth round before losing to Casper Ruud. This is not Altmaier's first big win at the French Open. He beat No. 8 seed Matteo Berrettini there in 2020, and Sinner in 2023. ___ AP tennis:https://apnews.com/hub/tennis
