Switch-pitching

If I knew this I had forgotten but was pointed to this great article by Jerome Holtzman on the switch pitching of Greg Harris who worked a scoreless inning in 1995 using both arms:

"The play-by-play follows: Pitching right handed, Harris retired the righty-hitting Reggie Sanders who swung at the first pitch and grounded to short. The next two batters were Hal Morris and Ed Taubensee, both left-handed hitters. Throwing with his left hand, Harris walked Morris on four pitches. Taubensee carried Harris to a full count and hit a nubber in front of the plate. Harris switched back to his right hand for the righty-hitting Bret Boone, who grounded to the mound for the third out."
