Al Unser Jr. was in the hospital when he clinched his first CART PPG Cup Indy-car championship.
Unser, 28, was banged up in a three-car crash midway through yesterday's Spark Plug Grand Prix at Pennsylvania International Raceway in Nazareth, Pa., a race Emerson Fittipaldi won.
Unser, who clinched the title over Michael Andretti, was diagnosed as having a mild concussion and was released.
He had only to finish sixth or better to clinch the $400,000 season championship. He won the title with one race remaining when Andretti, the only driver with a chance of catching him, fought handling problems and wound up fifth.
On Lap 112, Unser was preparing to pass lapped cars in Turn 3 when Arie Luyendyk and Danny Sullivan crashed, sending Luyendyk's car into Unser's Lola and sliding both into the wall. Luyendyk and Sullivan, both uninjured, blamed each other.
On the one-mile tri-oval, Fittipaldi, who led 166 of the 200 laps, held off Penske Racing teammate Rick Mears. In the pit stop during a caution preceding the final 32 miles, Mears was out in 3.6 seconds and got in line with only one car between himself and Fittipaldi.
Mello Yello 500: Davey Allison, capitalizing on Bill Elliott's tire troubles with 100 miles left, held off Morgan Shepherd by 3.4 seconds to win the Winston Cup race at Charlotte Motor Speedway in Harrisburg, N.C. It was his eighth career win and second this season. In a Ford Thunderbird, he averaged 137.375 mph.
Elliott, who led 243 laps, dominated until No. 258, when the left rear tire of his Thunderbird lost pressure. Following a series of late green-flag pit stops late in the race, Allison moved past Michael Waltrip into the lead for good with 11 laps left.
