 Kelley moved back to the infield , becoming the regular first baseman in 1901 . After the 1901 season , Kelley denied reports that he would jump from the Superbas to the Detroit Tigers of the American League ( AL ) , the former Western League which had decided to compete with the NL by creating franchises in east coast cities that housed NL franchises . However , the opportunity to return to Baltimore proved irresistible to Kelley , and after the AL 's successful 1901 season , he jumped from the Superbas to the Baltimore Orioles AL . Kelley 's father @-@ in @-@ law , John Mahon , was president and principal share holder of the AL 's Orioles .
