Two very unusual races occurred this past Sunday. At the Indy 500, Alexander Rossi, a 24-year old rookie driver from California, out-smarted his more seasoned opponents and won the 100th Indy 500 race. Before more than 350,000 fans, he stretched his fuel and coasted across the finish line with the most coveted prize in open-wheel racing.At the Coca-Cola 600 in North Carolina, Martin Truex, Jr., led all but 12 miles of the 600-mile race to totally dominate the NASCAR field. The New England driver, who has had several near wins this year, finally put it all together and basically led from start to finish. Only once during this race was he passed while cars were running at top speed. Before the lap was completed, he regained the lead and cruised to the victory.I enjoyed watching both races, and I was glad to see that an American won the 500. I was also happy to see that single-car racer Truex beat the big boys and won the 600. He is the only driver for this operation.
