PEORIA, Ariz. -- Right-hander Philip Humber has told the San Diego Padres he's retiring instead of accepting a minor league assignment.
Also Tuesday, the Padres told veteran reliever Matt Thornton that he will make the 25-man roster, paid a retention bonus to right-hander Brandon Morrow, released outfielder Skip Schumaker and optioned right-hander Leonel Campos to Triple-A.
Humber threw a perfect game for the Chicago White Sox against Seattle in 2012.
