2nd  Eddie Bane of Arizona State University pitches a 9–0 perfect game against Cal State Northridge University. Bane will rack up a record of 41–4 in college and, after being drafted by the Twins, jump right to the majors.

5th  Yankee teammates Fritz Peterson and Mike Kekich arrive at spring training and announce that wives and families have been swapped. Even the family dogs were traded.  The swap began as a joke over dinner between the two pitchers.  Peterson’s marriage to Susan Kekich will endure while Mike Kekich’s marriage will not last the year. Yankees executive Dan Topping said after the trade was announced, “We may have to call off Family Day this season.”

6th  In an exhibition game with the Pirates, the Twins Larry Hisle becomes the first designated hitter in ML history. Hisle makes the new AL rule look good by collecting 2 HRs and 7 RBI.

20th  In a special election held by the BBWAA, the late Roberto Clemente receives 393 of 424 votes to earn entry in the Hall of Fame. The Hall’s Board of Directors had earlier waived the 5-year-wait rule for Clemente.

The Red Sox swap Andy Kosko and Phil Gagliano to the Reds for P Mel Behney, who was 0–2 for the Reds in 1970. His ML record will remain unchanged.

29th  Orange baseballs, the brainchild of Oakland owner Charlie Finley, are used in the A’s 11–5 exhibition loss to the Indians. The Dodgers used yellow baseballs in league games in 1939.
