O’Connell guard Melo Trimble and Bullis center Lynee’ Belton played in the McDonald’s All American games in Chicago Wednesday night, with both players representing the East All-Stars in the annual showcase event.

The West all-stars won both the boys’ and girls’ games by narrow margins. In the boys’ game, the West won 105-102 behind an electrifying performance from co-MVP Jahlil Okafor, the country’s top recruit who is headed to Duke. The East was led by 23 points from North Carolina signee Justin Jackson, who shared MVP honors with Okafor.

The West girls won 80-78 despite a strong performance from Belton, who is headed to Duke. Belton scored 11 points and grabbed eight rebounds in just 15 minutes of play, and she hit five of six free throws.

It was a solid showing to cap a terrific career by Belton, who helped lead her team to an Independent School League AA title in 2013 and overcame a head injury (she missed 12 games to start the season) in 2014 to average 19.3 points and 11 rebounds per game.

Trimble, one of the area’s most exciting players who is expected to strengthen Maryland’s backcourt next season, played 13 minutes and finished with two points and one assist.

The 6-foot-3 Trimble, who led the Knights to a WCAC title, raised his profile as a senior and also became a more polished point guard. He averaged 22.3 points per game (including a 35-point, 13 assists and 11 rebounds in his final high school game) in earning league player of the year honors and helping the Knights win 20 games.

The East boys’ team was coached by Riverdale Baptist Coach Lou Wilson, who has coached the Crusaders for the past eight years and led the school to a 30-9 record and Maryland Private School Tournament championship in March.
