MLB Baseball Quiz
Home run kings, the Iron Man, a World Series perfect game and 50/50: 15 questions on Major League Baseball.
How many players does each team have on the field while playing defense in baseball?
Got a hunch? Pick the answer that feels right.
9
Nine fielders take the field: the pitcher, the catcher, four infielders at first, second, third and shortstop, and three outfielders, which is why a lineup has nine batting spots.
The designated hitter bats for the pitcher but does not take the field, so a team's active lineup can involve ten players.
Which team has won the most World Series championships?
Got a hunch? Pick the answer that feels right.
New York Yankees
The New York Yankees have won 27 World Series titles, the first in 1923 and the most recent in 2009, more than twice as many as the second-placed St. Louis Cardinals with 11.
The Yankees won five straight World Series from 1949 to 1953, a streak no other team has matched.
Which player's number 42 has been retired by every team in Major League Baseball?
Got a hunch? Pick the answer that feels right.
