BALTIMORE (AP) _ Two fires, neither of them major, broke out at Pimlico Race Course on Saturday, hours before the Preakness, but were not expected to affect the running of the race.

A transformer fire knocked out power, halting betting in the clubhouse and part of the grandstand, but not in the infield.

The fire erupted about 1:20 p.m. near the entrance to the horsemen's parking lot, just before the fifth race. About the same time, another blaze broke out in an overheated air conditioner in the Hall of Fame dining room near the jockeys' locker room.

No injuries were reported.

Betting windows closed because of the power failure, but began to reopen after 2 p.m. Automated machines used in the infield continued to operate, but tellers could not accept bets and gamblers could not cash in winning tickets.

Pimlico owner Joseph DeFrancis said the Preakness would be run as scheduled, regardless of the power outage. The fifth and sixth races went off as scheduled.

ABC brought in generators to provide power for televising the middle race in the Triple Crown series even if the power is out.
