Even while Hubbard's football career was going full-force, he began to focus on a second career in baseball officiating. From 1928 onward he spent his football off-season umpiring in [[minor league baseball]].<ref name=MSHS/> By 1936 Hubbard had been called up to the major leagues, umpiring in the [[American League]] from 1936 to 1951, a contemporary with the likes of [[Yogi Berra]].<ref name=bigumpire/> Soon recognized as one of the game's best officials, he was selected to work in the [[1938 World Series]], followed by Series appearances in [[1942 World Series|1942]], [[1946 World Series|1946]] and [[1949 World Series|1949]].<ref>{{cite news|url=https://news.google.com/newspapers?nid=2002&dat=19771017&id=Tw4vAAAAIBAJ&sjid=3toFAAAAIBAJ&pg=1282,3478180&hl=en|title=A Legend dies|work=Beaver County Times|date=October 17, 1977}}</ref>  In addition, he umpired in the [[Major League Baseball All-Star Game|All-Star Game]] in [[1939 Major League Baseball All-Star Game|1939]], [[1944 Major League Baseball All-Star Game|1944]] and [[1949 Major League Baseball All-Star Game|1949]], behind the plate for half of the 1939 and 1944 midsummer classics.<ref name=mohof/>

Hubbard found the then-common practice of officials moving to different positions on the field during a game to be confusing and hampered accuracy when making calls. Applying his football experience to baseball, he devised a system where each official had clearly defined duties and also added an additional official to the crew.<ref name="Packers" /> This was the foundation on which MLB established new officiating standards in 1952.<ref name=mohof>{{cite web|url=http://mosportshalloffame.com/inductees/cal-hubbard-3/|archive-url=https://web.archive.org/web/20160617082627/http://mosportshalloffame.com/inductees/cal-hubbard-3/|url-status=dead|archive-date=June 17, 2016|title=Cal Hubbard – Missouri Sports Hall of Fame|work=Missouri Sports Hall of Fame}}</ref>

While he was hunting during the 1951 off-season, a ricocheting pellet from a friend's shotgun blast accidentally struck Hubbard in the right eye.<ref>{{cite web|url=http://baseballhall.org/hof/hubbard-cal|title=Hubbard, Cal – Baseball Hall of Fame|work=Baseball Hall of Fame}}</ref> The damage was extensive enough to force his retirement from baseball officiating. However, the American League soon hired him as an assistant supervisor for league officiating crews, and in 1954 he became the top supervisor, a position he would hold until retiring for good in 1969.<ref name=MSHS/>
