I played with 4 different Arrieta's that I can think of just off the top of my head. With some research of my old programs I might come up with more. And then there were several that played before and after my time.
In Miami I played with Inaki Arrieta and in Tampa I played with his brother Jose Arrieta (Arri). Their other brother Alex played in Dania. All were frontcourters.
There were 2 backcourters, Arrieta...who played on the prestrike 1968 roster in Miami and then played in Bridgeport. There was a young Arrieta who played several seasons in Ft. Pierce and Ocala. He was a black Basque player if that helps.
There was another Arrieta backcourter who played as 'Ari' at Miami during 1969-1970 season.
Any special reason for the interest Tiger? There has been just as many Arriaga's... just saying.
