1947 and 1948 weren't so kind to Wright and he found himself back in the minors in 1949, resurfacing for a short while in 1952 with the Philadelphia A's.
His Baseball Reference major league page has the following for his transactions:
Before 1949 Season: Sent from the Boston Braves to the Philadelphia Phillies in an unknown transaction.
Well, he was in Milwaukee at the end of 1948, the Boston minor league club, then Toronto of the Phillies system in 1949. We find out how that happened in this from the Feb. 8, 1949 Milwaukee Journal...
“The Brewers Monday [Feb. 7] announced the sale of pitcher Ed Wright to the Toronto Maple Leafs of the International league. Wright, 30, spent the 1948 campaign with the Brewers on option from the parent Boston Braves, winning nine games and losing 12, and was purchased outright at the end of the season.”
So the Braves sold him outright to the Milwaukee club, then Milwaukee sold him to Toronto!
July 5, 1950: Traded by the Philadelphia Phillies to the New York Giants for Donald Robertson (minors). (Date given is approximate. Exact date is uncertain.)
from the July 7, 1950 Toledo Blade:
“The Minneapolis Millers have traded pitcher Don Robertson to Toronto of the International League in exchange for hurler Ed Wright.”
He was in the Phillies organization for a season and a half, then went in a deal to the Giants' Minneapolis team.
A 2-1 record with an ERA over 6.50 in his 1952 A's stint was the last Wright pitched in the majors. Not listed on the Baseball Reference site is what the A's did with his contract. From the Victoria Advocate of Feb. 6, 1953...
“The Athletics….sold pitcher Ed Wright to Memphis in the Southern Association.”
Wright made a few more lower minor league stops before he was done pitching.
