Cars for four-time Indy winner Al Unser, veteran Roberto Guerrero and rookie Eddie Cheever were entered today for the May 27 Indianapolis 500.
Unser and Guerrero were listed as the drivers of four 1990 March cars entered by Patrick Racing of Indianapolis, which won the 500 last year with driver Emerson Fittipaldi.
Cheever, a Formula One road racing veteran, was listed as driver on three Penske-Chevrolet entries for a new team headed by Chip Ganassi, Patrick's former partner.
Fittipaldi also left Patrick at the end of last season to join former winners Rick Mears and Danny Sullivan with the Penske Racing team, which has not yet submitted its entries for this year's race.
Unser, 50, who won his fourth Indy 500 while driving for Penske in 1987, will be seeking his 25th start at the Indianapolis Motor Speedway. He holds the Indy record for laps led with 625 and is second in all-time earnings at $2.68 million.
Guerrero, who finished second to Mears in 1984 and to Unser in 1987, will be trying for his sixth Indy start.
Cheever, 31, who was born in Phoenix but now lives in Monte Carlo, has driven in one Indy-car race, at Miami in 1986, but has 132 career Formula One starts since 1978. His best finishes were second in the 1982 U.S. Grand Prix East and the 1983 Canadian Grand Prix.
The seven entries raised the total received so far by the Speedway to 35. The entry deadline is midnight April 2.
