Nine members were inducted into the Washington D.C. Sports Hall of Fame on Sunday at Nationals Park. This year's class includes 20-year-old Katie Ledecky of Bethesda, who endeared herself to a Washington crowd last year when she brought the five Olympic swimming medals she won in Rio de Janeiro to the mound to throw out the first pitch — and made Bryce Harper hold them. The Hall also inducted former NFL commissioner Paul Tagliabue, who played basketball at Georgetown and practiced law in D.C. It inducted current Maryland women's basketball coach Brenda Frese and former Maryland basketball standout Juan Dixon (Calvert Hall), who is now coaching at Coppin State. Fellow Maryland basketball star Tom McMillen, who also played for the Bullets, went in, too. Former Washington Post columnist and sports radio legend Tony Kornheiser joined the Hall of Fame. Capitals radio announcer Ron Weber also earned a plaque. Glenn Harris, longtime host of SportsTalk on Newschannel 8, became the latest TV personality to join. Mike Nelms, the former Redskins special teams standout, also gained a spot.

After sitting out the Atlanta Hawks' first summer league game in Las Vegas on Friday, former Maryland center Diamond Stone got his first chance with his new team Sunday and made a positive first impression. Looking leaner and more athletic than he did in College Park, Stone finished with 11 points and five rebounds in 14 minutes off the bench in an 84-82 win over the New Orleans Pelicans. "I like Diamond Stone. He played limited minutes, but he had a fantastic first outing," former NBA guard and television analyst Steve Smith said after the NBA TV telecast. Not only does Stone have a good chance to make the Hawks' roster, he also appears to have a shot at being a rotation player for a team that appears to be in a total rebuild after trading center Dwight Howard to the Charlotte Hornets and letting four-time All-Star Paul Millsap leave through free agency. The Hawks drafted former Wake Forest star John Collins in the first round, but the 6-10, 235-pound Collins seems more comfortable facing the basket than inside. Collins finished with 22 points and 10 rebounds in 24 minutes Sunday. Coming off the bench, Stone was active from the start. He scored three quick baskets after replacing Richard Solomon, the third a thunderous dunk off an offensive rebound. He gave the Hawks the lead with back-to-back baskets in the fourth quarter. Aside from Collins, the only center the Hawks have under contract is Miles Plumlee. Stone, who was traded to the Hawks as part of a three-team trade last week, spent most of his rookie season with the Los Angeles Clippers in the Development League after being drafted No. 40 overall by the Pelicans and traded to the Clippers on draft night.
