Joining the Brewers in September 1976, Thomas played 54 games for the Brewers in 1976 and 1977 as an outfielder and designated hitter. He had a career batting average of .274, an on-base percentage of .363, and a .457 slugging percentage. When he arrived for spring training in 1977, he informed the Brewers that he would not play on the Sabbath, from sundown Friday to sundown Saturday. "The Sundown Kid", as he came to be called, missed a night game on Saturday, April 23, 1977, when he was slated to be in the lineup as
cleanup hitter and left fielder, after having been excused from pre-sundown batting practice earlier in the day. Thomas said he heard on the radio that he was scheduled to play in the game and apologized to Brewers manager
Alex Grammas. Thomas was also outspoken in criticizing pitchers who
hit batters, saying, "I think they ought to make a rule that if a guy gets hit and is able to get up, they should tie the pitcher's hands behind his back and let the hitter smack him in the face." ==End of his baseball career==
