My memory is that the run-ins happened when Allen disagreed with claimed “supremacist” remarks made by Thomas.
Wikipedia proceeds to record a portion of Allen’s scratches during his time with the Phillies;
He rapidly stayed around too long because of flighty conduct. He got in a fistfight with the prevalent Phillie Frank Thomas in July 1965, sliced his tossing hand by driving it through a agent seth levinson front light on August 24, 1967, and earned a 26-diversion suspension in June 1969 in the wake of being ceased by police for unpredictable driving, and appearing late to a doubleheader; he additionally started drinking intensely.
Indeed, even Allen’s name was a wellspring of debate: he had been referred to since his childhood as “Dick” to family and companions, however for reasons which are fairly dark at this late date, the media alluded to him upon his landing in Philadelphia as “Richie,” potentially a conflation with the long-term Phillies star Richie Ashburn. Following quite a long while, he requested to be classified “Dick,” saying Richie was a young man’s name.
The Phillies’ Boo Bird fans, known for pummeling main residence players even in the best of times, exacerbated Allen’s issues. At first the maltreatment was verbal, with obscenities and racial appellations. In the long run Allen was welcomed with showers of organic product, ice, deny, and even electric lamp batteries as he took the field. He started wearing his batting protective cap even while playing his guarded position in the field, which offered ascend to another epithet, “Crash Helmet”, abbreviated to “Crash”.
One of Dick Allen’s most rankling minutes to fans was on June 24, 1969. Allen was fined $2,500 and suspended uncertainly when he neglected to show up for the Phillies twi-night doubleheader diversion with the Mets. Allen had gone to New Jersey in the first part of the day to see a steed race and got captured in rush hour gridlock attempting to return.
