The Mariners also tie a team record with seven homers in the game. James Baldwin is the easy winner, with seven innings pitched. There had only been 39 previous occasions of a player hitting two home runs in an inning, according to the Elias Sports Bureau. Eric Karros was last to do it, on August 22, 2000, for the Dodgers. Mark McGwire was the previous AL player to do it, on September 22, 1996, for Oakland.

He also surpasses Joe Adcock's former mark of 18 total bases, set in 1954. According to the Elias Sports Bureau, six players have produced 17 or more total bases in a game, with the last being Mike Schmidt in 1976. Green also is the first major league player to collect six hits while hitting four homers, and his four homers plus a double ties the NL mark for extra base hits. The Dodgers hit eight homers in the game, another franchise record. Before today's power display, Green had gone 0-for-15, and had been benched May 18.

On May 2, 1964, the Minnesota Twins hit four consecutive home runs, also in the top of the 11th inning, as Tony Oliva, Bob Allison, Jimmie Hall and Harmon Killebrew went deep in a 7–3 victory against the Kansas City Athletics.^[2]

June

• June 2 – Philadelphia Phillies pitcher Robert Person puts on one of the best offensive displays by a pitcher in Major League history. In his team's 18–2 victory over the Montreal Expos at Veterans Stadium, he hits two home runs and drives in seven runs. The first home run is a grand slam and comes off Bruce Chen in the first inning; the second comes in the fifth off Masato Yoshii with two men on base. In between, in the third inning, he barely misses joining Tony Cloninger in 1966 as the only pitchers to hit two grand slams in the same game; he strikes out to end the inning. With the second grand slam, Person, the first Phillie pitcher to hit two home runs in one game since Randy Lerch in 1978, would also have broken Cloninger's record of nine RBIs in one game by a pitcher, as well as become only the second pitcher to hit three home runs in one game, joining Jim Tobin in 1942.
• June 4 – The Minnesota Twins score 10 runs in the 7th inning to close out the scoring in a 23–2 win over the Indians, the largest margin of victory in Twins history.

They also tie the AL record as four players have four or more hits – Jacque Jones, Dustan Mohr, A. J. Pierzynski and Luis Rivas. Rivas scores five times to tie a club record. The Indians tie their team record for biggest loss, tying the mark set in a 21–0 loss to the Tigers on September 15, 1901. Cleveland also becomes the first team since the 1969 San Diego Padres to lose two games in the same season by 19 or more runs.
• June 10 – In an interleague game against the Arizona Diamondbacks at Yankee Stadium, Marcus Thames of the New York Yankees becomes the first player ever to hit a home run off a defending Cy Young Award winner in his very first Major League at-bat.

• June 18 – Jack Buck, Hall of Fame Broadcaster for the St. Louis Cardinals, passes away after months of hospitalization.

Chicago Cubs catcher Joe Girardi (who later played for the Cardinals) made the announcement to the crowd that the game was canceled due to a "tragedy in the Cardinal family." The game was rescheduled for August 31 with the Cardinals winning 10–4.

• June 28
  • The Tampa Bay Devil Rays defeat their cross-state rival Florida Marlins, 4–0 behind Wilson Álvarez and two relievers. Kevin Millar of the Marlins hits a towering fly that lands on one of the catwalks that hang from the stadium's dome. It never comes down and is ruled a double. It's the second time a ball has gotten stuck in a catwalk at Tropicana Field. In 1999, José Canseco hit a home run drive that lodged there. Millar joins Ruppert Jones, Ricky Nelson, Dave Kingman, Álvaro Espinoza and Canseco as the only players in major league history to hit a fair ball that got stuck in a stadium obstruction; Jones and Nelson both had hits get caught in the overhead speakers at the old Kingdome, while the balls hit by Kingman and Espinoza were at the Hubert H. Humphrey Metrodome, with Kingman's getting stuck in a drainage valve and Espinoza's lodging in an overhead speaker.
