» May 18, 1912: The Tiger players protest Ty Cobb's suspension and vote to strike. Faced with a $5,000 fine for failing to field a team, club owner Frank Navin orders manager Hugh Jennings to sign up some local amateurs. Al Travers, Bill Leinhauser, Dan McGarvey, Billy Maharg (whose real name was Graham, "Maharg" reversed), Jim McGarr, Pat Meany, Jack Coffey, Hap Ward, and Ed Irvin put on Tiger uniforms. Two Detroit coaches, Joe Sugden, 41, and Jim McGuire, 48, complete the lineup, and score the only two runs for Detroit. The Athletics win 24–2, as Travers goes all the way, giving up 26 hits and 24 runs in eight innings. The only recruit to hit for Detroit is Irvin, who laces two triples in three at bats and closes his ML career with a 2.000 slugging average (only three other players will debut with two triples -— Roy Weatherly, Willie McCovey, and John Sipin). Only one ever plays another ML game: Maharg will bat once for the Phils in 1916. He will also be involved as a conspirator in the Black Sox scandal of 1919. A's starter Jack Coombs leaves after three innings with a 6–0 lead, good enough for a win under the rules at the time. Boardwalk Brown and Herb Pennock divide the rest of the pitching for the A's. Starter Travers, having pitched his only ML game, returns to his studies at St. Joseph's College and later becomes a Catholic priest.

» May 24, 1969: Padres rookie 2B John Sipin debuts with a pair of triples, only the 4th player to do so, in a 7–5 San Diego loss to the Cubs. They are the only triples of his 68-game career. Sipin bangs his three-baggers in the 1st and 4th innings, off Ken Holtzman.

» May 30, 1969: John Sipin hits a leadoff homer in the 10th inning, his first ML home run, to give the Padres a 3–2 win over the Expos. It's the Expos 14th straight loss.
