The following article details the history of Major League Baseball on ABC, the broadcast of Major League Baseball games on the ABC television network.

1950s In 1953, ABC executive Edgar J. Scherick (who later created Wide World of Sports) broached a Saturday Game of the Week, sports television's first network series. At the time, ABC was labeled a "nothing network" that had fewer outlets than CBS or NBC. ABC also needed paid programming or "anything for bills" as Scherick put it. At first, ABC hesitated at the idea of a nationally televised regular season baseball program. ABC wondered how exactly the Game of the Week would reach television in the first place and who would notice if it did? Also, Major League Baseball barred the Game of the Week from airing within 50 miles of any ballpark. Major League Baseball according to Scherick, insisted on protecting local coverage and didn't care about national appeal. ABC, though, did care about the national appeal and claimed that "most of America was still up for grabs."

In April 1953, Edgar Scherick set out to acquire teams rights but instead, only got the Philadelphia Athletics, Cleveland Indians, and Chicago White Sox to sign on. These were not "national" broadcast contracts since they were assembled through negotiations with individual teams to telecast games from their home parks. It was until the Sports Broadcasting Act of 1961, that antitrust laws barred "pooled rights" television contracts negotiated with a central league broadcasting authority.

In 1953, ABC earned an 11.4 rating for its Game of the Week telecasts. Blacked-out cities had 32% of households. In the rest of the United States, 3 in 4 television sets in use watched Dizzy Dean and Buddy Blattner (or backup announcers Bill McColgan and Bob Finnegan) call the games for ABC. CBS took over the Saturday Game in 1955 (the rights were actually set up through the Falstaff Brewing Corporation) retaining Dean/Blattner and McColgan/Finnegan as the announcing crews (as well as Gene Kirby, who produced the Dean/Blattner games and alternated with them on play-by-play) and adding Sunday coverage in 1957. As Edgar Scherick said, "In '53, no one wanted us. Now teams begged for "Game"'s cash."

In 1959, ABC broadcast the best-of-three playoff series (to decide the National League pennant) between the Milwaukee Braves and Los Angeles Dodgers. The cigarette company L&M sponsored the telecasts. George Kell and Bob DeLaney were the announcers. ABC Radio also broadcast the playoff series with Bob Finnegan and Tony Flynn announcing.

1960s 1960–1961 In 1960, ABC returned to baseball broadcasting with a series of late-afternoon Saturday games. Jack Buck and Carl Erskine were the lead announcing crew for this series (branded on air, as Big League Baseball), which lasted one season. ABC typically did three games a week. Two of the games were always from the Eastern or Central Time Zone. The late games (no doubleheaders) were usually San Francisco Giants or Los Angeles Dodgers' home games. However, the Milwaukee Braves used to start many of their Saturday home games late in the afternoon. So if the Giants and Dodgers were both on the road at the same time, ABC still would be able to show a late game.

One other note about ABC baseball coverage during this period. Despite temporarily losing the Game of the Week package in 1961, ABC still televised several games in prime time (with Jack Buck returning to call the action). This occurred as Roger Maris was poised to tie and subsequently break Babe Ruth's regular season home run record of 60. As with all Major League Baseball games in those days, the action was totally blacked out of major league markets. As a matter of fact, as documented in the HBO film 61*, the Maris family was welcomed into ABC's Kansas City, Missouri affiliate KMBC-TV so they could watch the in-house feed of the game, which was blacked out of Kansas City.

On September 20, 1961, Bob Neal and Hank Greenberg called a baseball game for ABC in prime time between Maris' New York Yankees and the Baltimore Orioles.

1965 In 1965, ABC provided the first-ever nationwide baseball coverage with weekly Saturday broadcasts on a regional basis. ABC paid $5.7 million for the rights to the 28 Saturday/holiday Games of the Week. ABC's deal covered all of the teams except the New York Yankees and Philadelphia Phillies (who had their own television deals) and called for two regionalized games on Saturdays, Independence Day, and Labor Day. Each Saturday, ABC broadcast two 2 p.m. games and one 5 p.m. game for the Pacific Time Zone. ABC blacked out the games in the home cities of the clubs playing those games. Major League Baseball however, had a television deal with NBC for the All-Star Game and World Series. At the end of the season, ABC declined to exercise its $6.5 million option for 1966, citing poor ratings, especially in New York.

According to ABC announcer Merle Harmon's profile in Curt Smith's book Voices of Summer, in 1965, CBS' Yankee Game of the Week beat ABC in the ratings in at least Dallas and Des Moines. To make matters worse, local television split the big-city audience. Therefore, ABC could show the Cubs vs. the Cardinals in the New York market, yet the Mets would still kill them in terms of viewership. Harmon, Chris Schenkel, Keith Jackson, and (on occasion) Ken Coleman served as ABC's principal play-by-play voices for this series. Also on the network's announcing team were pregame host Howard Cosell and color commentators Leo Durocher, Tommy Henrich, Warren Spahn (who worked with Chris Schenkel on a July 17, Baltimore-Detroit contest), and Hall of Fame Brooklyn Dodger great Jackie Robinson (who, on April 17, 1965, became the first black network broadcaster for Major League Baseball). According to ABC Sports producer Chuck Howard, "(Robinson) had a high, stabbing voice, great presence, and sharp mind. All he lacked was time."

The announcing duos were generally, Chris Schenkel-Leo Durocher and Merle Harmon-Jackie Robinson. For instance, the team of Schenkel and Durocher called the San Francisco-New York Mets contest on April 17, Milwaukee-Pittsburgh contest on August 21, and the San Francisco-Los Angeles (alongside Jackie Robinson) on September 6. The San Francisco-Los Angeles game on Labor Day was the first meeting between those two clubs since a melee from about two weeks prior involving Giants pitcher Juan Marichal cracking Dodgers catcher John Roseboro on the head during a brawl. Jackie Robinson worked with Merle Harmon on at least, the St. Louis-Cincinnati contest on April 24.

It was around this time that ABC suggested that Major League Baseball reduce their regular season schedule to just 60 games. ABC wanted the games to only be played on weekends. They also wanted to promote baseball in the same manner as football, as a major television event.

1970s

In March 1975, Commissioner Bowie Kuhn announced that ABC would join NBC in a new deal with Major League Baseball. The rights fees paid by the two networks were 29.3% higher than what MLB got in the 1971 deal, but adjusted for inflation, the money in the new deal was about the same as in the old one. Under the initial agreement (1976–1979), both networks paid $92.8 million.

ABC paid $12.5 million per year to show 16 Monday night games in 1976, 18 in the next three years, plus half the postseason (both League Championship Series in even numbered years and World Series in odd numbered years) and the All-Star Game in even numbered years. NBC paid $10.7 million per year to show 25 Saturday Games of the Week and the other half of the postseason (both League Championship Series in odd numbered years and World Series in even numbered years) and the All-Star Game in odd numbered years.

1976–1977 ABC also picked up the television rights for Monday Night Baseball beginning in 1976. For most of its time on ABC, the Monday night games were held on "dead travel days" when few games were scheduled. The team owners liked that arrangement as the national telecasts didn't compete against their stadium box offices. ABC on the other hand, found the arrangement far more complicated. ABC often had only one or two games to pick from for each telecast from a schedule designed by Major League Baseball. While trying to give all of the teams national exposure, ABC ended up with far too many games between sub .500 clubs from small markets. Reviewing the network's first two weeks of coverage for Sports Illustrated, William Leggett opined: "It may be unfair to say that Monday Night Baseball, as it has been presented by ABC so far this season, is the worst television treatment ever given a major sport, because by all odds somebody at sometime must have done something worse. But it is difficult to remember when or where that might have happened."

On the flip side however, ABC Sports head Roone Arledge brought in then innovative concept of a center field camera. This camera is behind the pitcher that looks at the batter's face. ABC Sports had to gain special permission from both Major League Baseball and the home team to put the camera in center field.

Just like with Monday Night Football, ABC brought in the concept of the three-man-booth (originally with Bob Prince, Bob Uecker, and Warner Wolf as the primary crew) to their baseball telecasts. Al Michaels, then the radio announcer for the San Francisco Giants, was brought in by ABC as the back-up announcer for Monday Night Baseball. That year, Michaels called two no-hitters: by the Pirates' John Candelaria vs. Los Angeles on August 9 (for ABC) and the Giants' John Montefusco at Atlanta on September 29, 1976 (for Giants radio). Michaels initially worked in the booth alongside Bob Gibson and Norm Cash. The following year, Cash would be replaced by Bill White, who himself, would remain with ABC through the 1979 season. All in all, the back-up telecasts were made available to an estimated 15% of the United States.

Roone Arledge stated that "It'll take something different for it to work – i.e. curb viewership yawns and lulls with Uecker as the real difference", so Arledge reportedly hoped. Prince disclosed to his broadcasting partner Jim Woods about his early worries about calling a network series for the first time. Prince for one, didn't have as much creative control over the broadcasts on ABC as he did calling Pittsburgh Pirates games on KDKA radio. On the June 7, 1976, edition of Monday Night Baseball, Prince returned to Three Rivers Stadium, from which he had been exiled for over a year. Although Prince received a warm reception, he was confused when the next day the Pittsburgh Post-Gazette read: "Ratings are low, negative reviews rampant." Critics ripped ABC's coverage for such things as its camera work (they often followed fly balls like they did golf shots, keeping the focus on the ball) and its choice of announcers: Bob Prince was accused of a National League bias, while Bob Uecker was considered to be just a Don Meredith clone.

On June 28, 1976, the Detroit Tigers faced the New York Yankees on Monday Night Baseball, with 47,855 attending at Tiger Stadium and a national television audience, Tigers pitcher Mark "The Bird" Fidrych talked to the ball and groomed the mound, as the Tigers won, 5–1 in a game that lasted only 1 hour and 51 minutes. After the game, the crowd would not leave the park until Fidrych came out of the dugout to tip his cap.

For ABC's coverage of the 1976 All-Star Game from Philadelphia, the team of Bob Prince, Bob Uecker and Warner Wolf alternated roles for the broadcast. For the first three innings, Prince did play-by-play with Wolf on color commentary and Uecker doing field interviews. For the middle innings, Uecker worked play-by-play with Prince on color and Wolf doing the interviews. For the rest of the game, Wolf worked play-by-play with Uecker on color and Prince doing interviews.
