In 2014, ESPN returned to broadcasting the Major League Baseball postseason, and has held the exclusive rights to the entire Wild Card Series since 2022.

For example, in 2007, ESPN and ESPN2 added several telecasts when Barry Bonds chased Hank Aaron's record for most home runs in an MLB career.

ESPN was also the broadcaster of the final game at the original Yankee Stadium as a part of Sunday Night Baseball with Jon Miller and Hall of Famer Joe Morgan.

It also showed Chris Burke's 18th-inning walk-off homer to end the 2005 NLDS series in favor of the Houston Astros against the Atlanta Braves.

Also, ESPN has been given permission to interrupt regular programming, when allowed, to show attempts at new records or significant milestones live.

On April 15, 1990, ESPN's Sunday Night Baseball debuted with the experienced play-by-play announcer Jon Miller joining retired Hall of Fame player Joe Morgan in the broadcast booth.

By 1998, ESPN enjoyed its largest baseball audience ever (a 9.5 Nielsen rating) as Mark McGwire hit his 61st home run of the season.

In 1995, ESPN broadcast the American League West tie-breaker game between the Seattle Mariners and California Angels with Jon Miller and Joe Morgan making the call.

In 1998, ESPN[5][6] broadcast the National League Wild Card tie-breaker game between the Chicago Cubs and San Francisco Giants.

Later that year, ESPN[10] broadcast the National League Wild Card tie-breaker game (this time between the New York Mets and Cincinnati Reds) with Miller and Morgan once again on the call.

[12] Reynolds confirmed that an accusation of sexual harassment was the reason for his departure but called it "a total misunderstanding" and that "I gave a woman a hug and I felt like it was misinterpreted.

The weekday afternoon DayGame telecasts continued through the 2006 season as they were still covered under the separate contract inherited from Fox Family.

On April 1, for the season-opening game between the New York Mets and the St. Louis Cardinals, ESPN changed its on-screen graphics to the version that debuted with Monday Night Football in 2006 and was later adopted by its NBA coverage at the start of the 2006-07 season.

The reason was that MLB stripped ESPN of its on-site credentials for its studio crew as punishment for leaking the rosters of the All-Star teams before TBS did.

TBS' announcement, which was billed as exclusive, was scheduled for 4 p.m. Eastern time but was delayed for nearly two hours, by which point ESPN, in apparent violation of its contract with MLB, went ahead and revealed the rosters anyway.

ESPN pre-empted part of the Kansas State–Auburn college football game on September 1 to show the end of the no-hitter thrown by Boston Red Sox pitcher Clay Buchholz.

Starting with the April 3 season opener between the New York Yankees and Boston Red Sox, ESPN began using the same graphics package which debuted with Monday Night Football in 2009.

The pitch count was also introduced, adopted from the New York Yankees' broadcasts on the YES Network, as well as NESN for the Boston Red Sox.

The ESPN Major League Baseball score box was slightly modified beginning with the opening day game between the Detroit Tigers and the New York Yankees.

[17] The new live K-Zone graphic was criticized by viewers and the media for being potentially distracting, drawing comparisons to baseball video games and Fox's "glowing puck" from its NHL coverage.

During the American League Wild Card Game, ESPN also introduced a new "immersive" K-Zone 3D component, which allows the data to be rendered into a virtual stadium environment to be viewed at different perspectives.

[20] The 2018 season saw a revamp of ESPN's lead commentary team, with Matt Vasgersian succeeding Dan Shulman, and Alex Rodriguez joining as analyst.

ESPN also anticipated increased use of the Front Row Cam on Sunday Night Baseball, and the immersive K-Zone 3D feature being employed on all games (a move enabled by ESPN's full adoption of on-site graphics and replay systems operated remotely from its main studios in Bristol).

Matt Vasgersian and Alex Rodriguez would broadcast all of ESPN's Sunday night games from a studio at their Bristol, Connecticut headquarters.

ESPN also received the rights to produce alternate telecasts on its sister networks, as well as simulcasts and expanded content on ESPN+, and the ability to air selected games on ABC.

[30] During the final three weeks of the season, ESPN or ESPN2 aired Baseball Tonight Special: MLB Squeeze Play on Wednesday nights.
