DERBY, Kan. (AP) — Investigators are trying to determine why the driver of a pickup truck drove into the dugout at a baseball diamond in a Wichita suburb. Three players of the Derby Twins, a summer-league college baseball team, suffered minor injuries when the truck hit their dugout Tuesday night. The driver was hospitalized in serious condition. Derby Police Chief Robert Lee says it's unclear why the truck went off a nearby road, through a chain-link fence and through the batting cages before hitting the dugout. The Wichita Eagle reports that Rickey Noland, coach of the Derby Twins, said witnesses saw the driver's face down at the steering wheel before the truck hit a transformer and veered into the dugout.
