PARIS -- Carlos Alcaraz opened his French Open title defense Monday with a 6-3, 6-4, 6-2 win over Giulio Zeppieri, an Italian qualifier who is ranked 310th. Alcaraz won all 14 of his service games, saving the three break points he faced, at Court Suzanne-Lenglen. "It was really, really solid," Alcaraz said. "Really proud about my start." Elsewhere in the men's bracket, fourth-seeded American Taylor Fritz crashed out of the tournament Monday after a 7-5, 3-6, 6-3, 6-1 loss to 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. Alcaraz is seeded No. 2 behind Jannik Sinner, who was scheduled to play Monday night, and is coming off a clay-court title at the Italian Open a little more than a week ago. Alcaraz beat Sinner in the final there. Monday's result gave Alcaraz 28 wins in his past 30 matches on red clay, including going 7-for-7 a year ago at Roland-Garros. One of the losses came against Novak Djokovic in the gold medal match at last year's Paris Olympics, held at the same site as the French Open. Also Monday, two-time runner-up Casper Ruud began his bid to reach another Roland Garros final with a 6-3, 6-4, 6-2 first-round victory over Spanish qualifier Albert Ramos-Vinolas.
