The 1988 Major League Baseball season ended with the underdog Los Angeles Dodgers shocking the Oakland Athletics, who had won 104 games during the regular season, in the World Series. The most memorable moment of the series came in Game 1, when injured Dodger Kirk Gibson hit a dramatic pinch-hit walk-off home run off Athletics closer Dennis Eckersley to win the game for Los Angeles. The Dodgers went on to win the Series in five games.
This would also be the final full season for Peter Ueberroth as MLB commissioner.
Speaking of the Dodgers, nobody expected them even to contend for the National League West title in 1988, let alone win the World Championship. [citation needed] However, the intensity and clutch hitting of Gibson (named the NL MVP at season's end) and the solid pitching of Orel Hershiser (who won a league-leading 23 games) spearheaded L.A. to a division championship by seven games over the Cincinnati Reds. In addition to his 23 victories, Hershiser led the National League with 267 innings pitched and 8 shutouts, and also set a record of 59 consecutive scoreless innings (formerly held by Dodger great Don Drysdale). These accomplishments, combined with his 2.26 ERA, earned him the National League Cy Young Award. However, it was in the postseason that Hershiser really distinguished himself – he started Games 1 and 3 of the NLCS against the tough New York Mets, saved Game 4 in relief, and threw a complete-game shutout in Game 7. He hurled another complete-game shutout in Game 2 of the World Series, and also helped his own cause going 3-3 at the plate with a run scored and an RBI, and again went the distance in the clinching Game 5. Hershiser was named MVP of both the NLCS and the World Series, capping off arguably one of the greatest seasons a starting pitcher has ever had.

October 12 – A gruelling seven-game NLCS is decided as the Los Angeles Dodgers blank the New York Mets 6–0. Orel Hershiser, who saved Game 4 and threw a complete-game shutout in Game 7, garners the Series MVP Award.
October 15 – In Game One of the 1988 World Series at Dodger Stadium, the Los Angeles Dodgers trailed the Oakland Athletics 4–3 in the bottom of the ninth inning when the Dodgers' Kirk Gibson, badly injured in the NLCS against the New York Mets, hobbles to the plate to pinch-hit against Oakland's lethal closer, Dennis Eckersley. With two outs, a 3–2 count against him, and Mike Davis on second base, Gibson uses his upper body and wrists to launch a backdoor slider from Eckersley into the right-field stands for a 5–4 Los Angeles victory. Gibson's home run re-energized the underdog Dodgers and shattered the confidence of the A's, who lost the series in five games. It inspired the coining of the phrase "walk-off home run", and is widely regarded as one of the greatest moments in baseball history.

December 14 – CBS pays Major League Baseball approximately US$1.8 billion[31] for exclusive over-the-air television rights for over four years (beginning in 1990). CBS paid about $265 million each year[32] for the World Series, League Championship Series, All-Star Game, and the Saturday Game of the Week. CBS replaces ABC (which had broadcast Monday and later Thursday night baseball games from 1976 to 1989) and NBC (which had broadcast Major League Baseball in some shape or form since 1947 and the Game of the Week exclusively since 1966) as the national broadcast network television home of Major League Baseball.[33] It was one of the largest agreements[34] (to date) between the sport of baseball and the business of broadcasting. The cost of the deal between CBS and Major League Baseball was about 25% more[35] than in the previous television contract with ABC and NBC.[36] The deal with CBS was also intended to pay each team (26 in 1990 and then, 28 by 1993) $10 million a year.
