Barlick returned to umpiring in 1946, when he umpired his first World Series. Klem repeated his endorsement of Barlick that year. "There's a fellow who's going to be one of the great all-time umpires. He's got everything and knows how to handle himself. Before I saw him, I predicted he'd be a great umpire just from what I heard about him." In 1947, Barlick was the first base umpire during Jackie Robinson's MLB debut. In 1949, Barlick was again chosen as an umpire for the 1949 All-Star Game. He began the game at home plate, although when it became time for the umpires to rotate, as was customary during All-Star games, Barlick left the game, leaving the right field line uncovered; no reason was given for his departure.
