In a 12-11, 10-inning loss to the A’s, Red Sox rookie Creighton Gubanich becomes only the fourth player to blast a grand slam for his first major league hit. The reserve catcher joins Bill Duggleby (1898 – Phillies), Bobby Bonds (1968 – Giants), and Orlando Mercado (1982 -Mariners) in accomplishing the feat.

In the second game of a home-and-home series, the Cuban national team, facing major league competition in the United States for the first time, defeats the struggling Orioles at Camden Yards, 12-6. In March, Baltimore, after being greeted by Fidel Castro, prevailed at Havana’s Estadio Latinoamericano, edging Cuba in 11 innings, 3-2.
