Frerotte, who has started 62 career games, had his best seasons with the Redskins from 1995 to '97. He passed for 3,453 yards in 1996 and threw 17 touchdown passes in 1997. . . .

Composure Retired

The filly Composure was retired because of a crack in her right front leg, leaving trainer Bob Baffert without one of his Kentucky Derby contenders.

Owned by Bob and Beverly Lewis, Composure won four of eight career starts, including a three-quarter length victory in the Santa Anita Oaks on March 8 in her last start.

Baffert was considering Composure for the Derby on May 3. Just 38 fillies have run in the Derby and only three have won, the last being Winning Colors in 1988.

Other Derby contenders knocked off the trail with injuries include Vindication, Toccet and Sky Mesa, the three top 2-year-old males from last year. . . .

Hall of Fame jockey Julie Krone said she expects to return from a broken back by the start of the Del Mar meet on July 23. Krone broke two bones in her back March 8 when her mount fell leaving the gate in a race.
