BASKETBALL

Oregon State men land 7-footer — Community college standout Roman Silva, a 7-foot-1 center from Rancho Cucamonga, California, has signed a letter of intent to join the Oregon State men’s basketball program for the 2019-20 season, Beavers head coach Wayne Tinkle and his staff announced Tuesday. “Roman will be a big, physical presence for us in the paint,” Tinkle said. “He’s a great rim protector with his size and length. We feel he’s an inside threat on both ends and will give us great depth at the center position.” Silva attended San Bernardino Valley College last season and was named Pacific Coast Athletic Conference North Division co-player of the year, averaging 16.1 points, 7.8 rebounds and 2.0 blocked shots per game while leading the team to a 22-7 record and the PCAC North championship. He will be eligible at Oregon State for the 2019-20 season and will have three years to complete two seasons.

TENNIS

Serena withdraws from tournament in Ohio —With less than two weeks before the start of the U.S. Open, Serena Williams withdrew Tuesday from a Cincinnati-area tournament, citing back issues. Williams pulled out of the Western & Southern Open before her opening-round match against Zarina Diyas. The decision came just days after the 37-year-old Williams tearfully retired during the final of the Rogers Cup in Toronto and ceded the title to Bianca Andreescu. In a statement released through the Western & Southern Open, Williams said she traveled Sunday to the tournament site in Mason, Ohio, and had “tried everything to be ready to play” Tuesday. She remained hopeful after practicing in the morning.
