RAILCATS SIGN TWO: The RailCats added pitcher John Boker and outfielder Cristrian Guerrero to the roster.

Guerrero, who is cousin to All-Star Major Leaguer Vladimir Guerrero, is entering his 11th year of professional baseball. The 27-year-old was originally signed as a nondrafted free agent by the Milwaukee Brewers in 1997.

Boker posted a 7-3 record for Brockton with a 4.98 ERA, but finished the season in Lancaster going 2-0 with a 3.10 ERA. The Mount Vernon Nazarene University product was originally drafted by the Milwaukee Brewers in 19th round of the 1996 amateur draft, but spent all of 1997 and 1998 on the disabled list before being released in 1999.

HANSBROUGH, DAVIS SWEEP AWARDS: Tyler Hansbrough had a very busy Friday morning on the biggest weekend of his young basketball career.

The North Carolina junior forward was selected The Associated Press' college basketball player of the year, an honor that came less than an hour after he was presented the Oscar Robertson Trophy by the U.S. Basketball Writers Association as their player of the year.

The ceremonies were a couple of blocks apart, and the 6-foot-9 Hansbrough, his coach and parents made the short walk.

Hansbrough led the Atlantic Coast Conference in scoring (22.8) and rebounding (10.3) as the Tar Heels (36-2) were ranked No. 1 for all but six weeks this season and were the overall top seed for the NCAA tournament.

Drake's Keno Davis was selected coach of the year by the AP, and he, too, had a busy morning as he swept the awards given Friday.

He and his father, Dr. Tom Davis, who won the award in 1987 at Iowa, became the first father and son to win the award.

Davis led Drake to a school-record 28 wins, its first Top 25 ranking since 1975 and its first NCAA tournament berth since 1971. He becomes the second straight first-year coach to win the award. Like Washington State's Tony Bennett last season, he succeeded his father as head coach.
