I found this on Baseball Almanac regarding Seby's 4ks yesterday.
The Major League record for most strikeouts during a players first game ever is four. Those who have worn a "golden sombrero" and entered this record book during their debut are: Billy Sunday (May 22, 1883), Hercules Burnett (June 26, 1888), George Goetz (June 17, 1889), Rollie Naylor (September 14, 1917), Lee Bales (August 7, 1966), and Sam Ewing(September 11, 1973).
