Roger Maris' 142 RBIs led the league in 1961. However, analysis by the Society for American Baseball Research determined Maris was incorrectly credited with an RBI in a game on July 5, 1961.

There isn't enough room in the Note2 field to add all this so here it is:
Pizarro is credited with 187 K's on the back; it should be 188, like on the front. Bunning is credited with 192 K's; it should be 194, like on the back. McBride is credited with 179 K's on the back; it should be 180. Ramos is credited with 172 K's; it should be 174. Barber is credited with 149 K's; it should be 150. I refuse to go beyond the top 10, but I'm sure there's plenty of other mistakes.

"Year" (1961) stats appear to be missing a July 6, 1961 appearance against the Washington Senators.

Hoeft entered the game to start the bottom of the 8th inning in a game that the Orioles trailed 1-0.
He walked Dick Donovan (1xBB), retired Danny O'Connell on a sacrifice bunt, struck out Marty Keough (1xK), and coaxed a Gene Woodling flyball to CF.
