Sports’ infiltration of Hollywood agencies continues.

WMA has signed Jason McElwain, the autistic teenager from Greece Athena High School in Rochester, N.Y., who scored 20 points after seeing action in the waning minutes of his team’s final game of the season.

WMA will represent McElwain, his family and basketball coach Jim Johnson to package a film deal about the student’s life.

McElwain was subsequently invited to meet President Bush, and his family has been swarmed by producers and dealmakers ever since.

WMA also is packaging a reality TV show for the Premiership champion Chelsea soccer team that will award a pro contract to an American contestant who emerges as the series victor. WMA is a consultant for the team, and the show will use the formula road-tested on “Football Icon,” a hit Sky TV reality show launched by the team last year.

Meanwhile, Creative Artists Agency has hired IMG’s Casey Close, a heavy hitter among baseball dealmakers, who’ll bring with him more than 70 pro and minor league players, including Yankees shortstop Derek Jeter and Cubs slugger Derrek Lee.

The move comes days after CAA hired from IMG football agents Tom Condon and Ken Kremer, who brought with them gridiron talent like brothers Peyton and Eli Manning.

Close will operate from New York, while the football agents will continue to operate from their base in Kansas City.

Separately, Gersh, which also just entered the sports field, has inked Stanford grad Jon Alston, a linebacker who figures to be a high-first-round pick in the upcoming NFL draft.
