Dick Allen hit a baseball with an authority Philadelphia fans had not seen since Chuck Klein and Jimmie Foxx. Phillies scout John Ogden convinced the Phillies to sign Allen in 1960 for a $70,000 bonus. Ogden had played for the International League Baltimore Orioles from 1919 to 1925, under Jack Dunn, the discoverer of Babe Ruth; Ogden later pitched against Ruth in the American League (AL). Ogden stated in a Philadelphia Bulletin story printed on July 1, 1969, that Allen was the only player he ever saw who hit a ball as hard as Ruth.

Allen finally had enough, and demanded the Phillies trade him. They sent him to the Cardinals in a trade before the 1970 season. Even this deal caused controversy, though not of Allen’s making, since Cardinals outfielder Curt Flood refused to report to the Phillies as part of the trade. (Flood then sued baseball in an unsuccessful attempt to overthrow the reserve clause and to be declared a free agent.) Coincidentally, the player the Phillies received as compensation for Flood not reporting, Willie Montañez, hit 30 home runs as a 1971 rookie to eclipse Allen’s Phillies rookie home run record of 29, set in 1964.

Allen hit a two-run home run off the Cubs’ Larry Jackson on May 29, 1965 that cleared the Coke sign on Connie Mack Stadium’s left-center field roof. That home run, an estimated 529-footer, inspired Willie Stargell to say: “Now I know why they (the Phillies fans) boo Richie all the time. When he hits a home run, there’s no souvenir.”

Non-baseball incidents soon marred Allen’s Philadelphia career. In July 1965, he got into a fistfight with fellow Phillie Frank Thomas. According to two teammates who witnessed the fight, Thomas swung a bat at Allen, hitting him in the shoulder. Johnny Callison said, “Thomas got himself fired when he swung that bat at Richie. In baseball you don’t swing a bat at another player—ever.” Pat Corrales confirmed that Thomas hit Allen with a bat and added that Thomas was a “bully” known for making racially divisive remarks. Allen and his teammates were not permitted to give their side of the story under threat of a heavy fine. The Phillies released Thomas the next day. That not only made the fans and local sports writers see Allen as costing a white player his job, but freed Thomas to give his version of the fight. In an hour-long interview aired December 15, 2009, on the MLB Network’s Studio 42 with Bob Costas, Allen asserted that he and Thomas are in fact good friends now.

While playing for Philadelphia, Allen appeared on several All-Star teams including the 1965–67 teams (in the latter of these three games, he hit a home run off Dean Chance). He led the league in slugging (.632), OPS (1.027) and extra base hits (75) in 1966.

He almost ended his career in 1967 after mangling his throwing hand by pushing it through a car headlight. Allen was fined $2,500 and suspended indefinitely in 1969 when he failed to appear for the Phillies twi-night doubleheader game with the New York Mets. Allen had gone to New Jersey in the morning to see a horse race, and got caught in traffic trying to return.

Decades before Mark McGwire, Dick Allen entertained the St. Louis fans with some long home runs, at least one of them landing in the seats above the club level in left field. As Buck said at the time, “Some of the folks in the stadium club might have choked on a chicken leg when they saw that one coming!” Nevertheless, the Cardinals traded Allen to the Los Angeles Dodgers before the 1971 season for 1969 NL Rookie of the Year Ted Sizemore and young catcher Bob Stinson. Allen had a relatively quiet season in 1971 although he hit .295 for the Dodgers.

Allen’s feats during his years with the White Sox — particularly in that MVP season of 1972 — are spoken of reverently by South Side fans who credit him with saving the franchise for Chicago (it was rumored to be bound for St. Petersburg or Seattle at the time). His powerful swing sent home runs deep into some of cavernous old Comiskey Park’s farthest reaches, including the roof and even the distant (445 feet (136 m)) center field bleachers, a rare feat at one of baseball’s most pitcher-friendly stadiums. On July 31, 1972, Allen became the first player in baseball’s “modern era” to hit two inside-the-park home runs in one game. Both homers were hit off Bert Blyleven in the White Sox’ 8–1 victory over the Minnesota Twins at Metropolitan Stadium. On July 6, 1974, at Detroit’s Tiger Stadium, he lined a homer off the roof facade in deep left-center field at a linear distance of approximately 415 feet (126 m) and an altitude of 85 feet (26 m). Anecdotal and mathematical evidence agreed that Allen’s clout would’ve easily surpassed 500 ft (150 m) on the fly.

The Sox were favored by many to make the playoffs in 1973, but those hopes were dashed due in large measure to the fractured fibula that Allen suffered in June. (He tried to return five weeks after injuring the leg in a collision with Mike Epstein of the California Angels, but the pain ended Allen’s season after just one game in which he batted 3-for-5.) In 1974, despite his making the AL All-Star team in each of the three years with the Sox, Allen’s stay in Chicago ended in controversy when he left the team on September 14 with two weeks left in the season. In his autobiography, Allen blamed his feud with third-baseman Ron Santo, who was playing a final, undistinguished season with the White Sox after leaving the crosstown Chicago Cubs.

The Phillies managed to coax Allen out of retirement for the 1975 season. The lay-off and nagging effects of his broken leg in 1973 hampered his play. His numbers improved in 1976, a Phillies division winner, as he hit 15 home runs and batted .268 in 85 games. He continued his tape measure legacy during his second go-round with the Phillies. On August 22, 1975, Allen smashed a homer into the seldom reached upper deck at San Diego’s Qualcomm (née Jack Murphy) Stadium.

Allen made one post-season appearance in the 1976 National League Championship Series as a member of the Phillies, batting .222 (2-9) with a run scored as the Phillies were swept by the Reds. Defensively, his best position was at first base, in which he compiled a .989 fielding percentage in 808 games. He also played 652 games at third base, 257 games in the outfield, and seven games at second base and shortstop.

Detractors of Allen’s Hall of Fame credentials argue that his career was not as long as most Hall of Famers, so he does not have the career cumulative numbers that others do. They further argue that the controversies surrounding him negatively impacted his teams. Hall of Fame player Willie Stargell countered with a historical perspective of Dick Allen’s time: “Dick Allen played the game in the most conservative era in baseball history. It was a time of change and protest in the country, and baseball reacted against all that. They saw it as a threat to the game. The sportswriters were reactionary too. They didn’t like seeing a man of such extraordinary skills doing it his way. It made them nervous. Dick Allen was ahead of his time. His views and way of doing things would go unnoticed today. If I had been manager of the Phillies back when he was playing, I would have found a way to make Dick Allen comfortable. I would have told him to blow off the writers. It was my observation that when Dick Allen was comfortable, balls left the park.” The two managers for whom Allen played the longest — Gene Mauch of the Phillies, and Chuck Tanner of the White Sox — agreed with Willie Stargell that Allen was not a “clubhouse lawyer” who harmed team chemistry. Asked if Allen’s behavior ever had a negative influence on the team, Mauch said, “Never. Dick’s teammates always liked him. I’d take him in a minute.” According to Tanner, “Dick was the leader of our team, the captain, the manager on the field. He took care of the young kids, took them under his wing. And he played every game as if it was his last day on earth.” Hall of Fame player Orlando Cepeda agreed, saying to author Tim Whitaker, “Dick Allen played with fire in his eyes.” Hall of Fame teammate Rich Gossage also confirmed Tanner’s view. In an interview with USA TODAY Sports, Gossage said: “I’ve been around the game a long time, and he’s the greatest player I’ve ever seen play in my life. He had the most amazing season (1972) I’ve ever seen. He’s the smartest baseball man I’ve ever been around in my life. He taught me how to pitch from a hitter’s prospective, and taught me how to play the game right. There’s no telling the numbers this guy could have put up if all he worried about was stats. The guy belongs in the Hall of Fame.” Another of Allen’s ex-White Sox teammates, pitcher Stan Bahnsen, said, “I actually thought that Dick was better than his stats. Every time we needed a clutch hit, he got it. He got along great with his teammates and he was very knowledgeable about the game. He was the ultimate team guy.” Another Hall of Fame teammate, Mike Schmidt, credited Dick Allen in his book, Clearing the Bases, as his mentor. In Schmidt’s biography, written by historian William C. Kashatus, Schmidt fondly recalls Allen mentoring him before a game in Chicago in 1976, saying to him, “Mike, you’ve got to relax. You’ve got to have some fun. Remember when you were just a kid and you’d skip supper to play ball? You were having fun. Hey, with all the talent you’ve got, baseball ought to be fun. Enjoy it. Be a kid again.” Schmidt responded by hitting four home runs in the game. Schmidt is quoted in the same book, “The baseball writers used to claim that Dick would divide the clubhouse along racial lines. That was a lie. The truth is that Dick never divided any clubhouse.”

Allen played in 54 games and hit 5 home runs with 31 RBI for a .240 batting average during his final season for the Oakland Athletics in 1977 before leaving the team abruptly in June of that season. His final day as a player was on June 19, playing both games of a doubleheader, against the White Sox. In five total plate appearances, he had two hits, with his final hit being a single in the eighth inning.

Sabermetrician Bill James rated Dick Allen as the second-most controversial player in baseball history, behind Rogers Hornsby. James called Allen’s autobiography, Crash, “one of the best baseball books in recent years.” For many years Allen held the distinction of the highest slugging percentage among players eligible for but not in the National Baseball Hall of Fame. This only ended in 2006, when Albert Belle became eligible but was not elected.

Although his music career was not as substantial or long-lasting as that of Milwaukee Braves outfielder Arthur Lee Maye, Allen gained lasting praise for a recording on the Groovy Grooves label titled, “Echoes of November.” The song is featured in the Philles official hundred-year anniversary video and the novel ’64 Intruder. In 2010, Brazilian pop star Ana Volans rerecorded “Echoes of November;” her rendition sold briskly in Brazil. (The CD’s jacket contains a dedication to Dick Allen and his Hall of Fame candidacy.)

Nearly 40 years after retiring, Allen remains a much discussed and still controversial ballplayer. An increasing number of Baseball historians regard him as the best player not inducted into the Baseball Hall of Fame. Allen appeared on the Hall of Fame’s 2014 Golden Era Committee ballot of 10 nominated candidates (selected by a committee of the Baseball Writers’ Association of America) from the 1947–1972 era for consideration for 2015 Hall of Fame enshrinement. (The committee had voted only one other time, 2011, when they elected Ron Santo.) Allen and Tony Oliva were both one vote short of the required 12 votes by the committee which elected none of the candidates. The committee was replaced by the Golden Days Committee in 2016, and votes next in 2020 (for induction in 2021).
