Danville police said 23-year-old Cainan Schierholtz, hit a bicyclist, a pedestrian, a truck, a light pole, and then a Sports Utility Vehicle.
Schierholtz is the brother of San Francisco Giants outfielder Nate Scheirholtz. Both men grew up nearby and graduated from San Ramon Valley High School.
Witnesses are being credited for physically taking Cainan Schierholtz down and holding him until police arrived.
People said he was so intoxicated he could barely speak.
Officers initially responded to reports of a Dodge pickup driving recklessly along Danville Boulevard and Railroad Avenue at about 10 a.m.
The driver kept going even though the airbags of his Dodge pickup had deployed.
The only serious injury was the bicyclist.
Schierholtz was booked for four counts of DUI causing bodily harm, three counts of hit and run causing personal injury, two counts of hit and run property damage, and driving without a license.
He is being held on $350,000 bail.
His sister told NBC Bay Area reporter Monte Francis that she was shocked to hear what her brother Cainan was accused of doing. Cainan lives with his sister and his mother in a trailer outside their three story home in Alamo. The home was badly damaged in a fire in March 2009 and is still under repair. His sister said she wasn't sure if her other brother Nate was aware of what happened prior to playing the Dodgers last night in a nationally televised game.
Cainan Schierholtz works at the Bridges Restaurant in Danville. His manager told Francis that he was one of her best employees.
