Borowy pitched reliably for the Yankees during WWII, going 15-4 as a 1942 rookie and following with 14-9 and 17-12 years. After a 10-5 start in 1945, he was suddenly sold to the Cubs on July 27 for $97,000. He went 11-2 for the remainder of the season, leading the NL in winning percentage (.846) and ERA (2.14), as the Cubs won the pennant. In the WS, he shut out the Tigers in the first game, lost the fifth game, and then came back to win the sixth with four scoreless relief innings. He started the final game on one day’s rest but gave up hits to the first three batters before leaving. TSN named him to the all-star ML team for 1945. During the remainder of his career, he was plagued by finger blisters and a sore shoulder.
