A native of Wheeling, West Virginia, Rose Gacioch was orphaned at the age of 16. She lied about her age, saying that she was 18 in order to take a job in a corrugating plant in her homeland. She also joined the Little Cardinals, a semi-professional baseball team in town, being the only girl on the team. What she considered her best pitch was the curveball which she had learned from her brother Steve, the oldest of four Gacioch children and the only boy. One afternoon in 1934, the president of the corrugating company came to a Little Cardinals game. He meet Maud Nelson, the manager of the All-Star Ranger Girls, and asked her if she could swing through Wheeling on her next tour, and give Gacioch a tryout. Gacioch did good, as Nelson signed her for the Rangers, where she alternated between the outfield and pitching. By then, women athletes hurried right into these teams. The trousers she used gave their name to pioneer women’s baseball players, who were called Bloomer Girls. But 1934 was the last year that the Bloomer Girls teams would play. Local companies that had sponsored women’s baseball were switching over the less expensive game of softball, an activity that relied mainly on a strong player, as is the pitcher. So Gacioch, like most other women players, switched to softball, barnstorming around the Midwest on weekends for as much as $50 for two days’ play. She was working in a factory during World War II when she read about the new women’s baseball league, the All-American Girls Baseball League, being formed. At 29, she was a bit old to play baseball. Nevertheless, a co-worker said her that his daughter was a chaperone for the South Bend Blue Sox, and he would ask her to come and look Gacioch up. Her chance came with a tryout at Pulaski Field in South Wheeling, just two blocks from her home.

For Rose Gacioch, the result was a return to baseball as a member of the 1944 Blue Sox. The team was managed by Bert Niehoff, the same man that had sent pitcher Jackie Mitchell to face Babe Ruth and Lou Gehrig a decade earlier in an exhibition game. As it is reported, she struck out Ruth And Gehrig in succession. At the end of the 1945 season, Gacioch was one of the ten players on the Blue Sox that Niehoff asked to have protected from being traded at a league meeting in Chicago. But the president of the South Bend club decided that Gacioch’s poor English made her a liability for the team, not the ladylike image he was seeking for his organization. And so he traded her to the Rockford Peaches for the 1945 season. After the transaction, Gacioch blossomed as one of the most consistent AAGPBL players, starring on three championship teams for the Peaches, and by setting several league records as both a hitter and a pitcher. During her first year in Rockford she set a league record of 31 assists from outfield, a mark she matched two years later. Then in the 1946 season, she led the league with nine triples while hitting a hefty .262 of batting average. Peaches manager Bill Allington moved Gacioch from the outfield to the pitcher’s mound in 1948, and she responded with 14–5 mark. Her most productive season came in 1951, when she posted a 20–7 record to become the league’s only 20-game winner. She also pitched a no-hitter in 1953, and while not pitching played in the outfield, she amaased averages of .294 in 1951, .285 in 1953, and a top-career .304 in 1954 at age of 38, when she was old enough to be the mother of some of her teammates. Also in her final season, she recorded a significant total of 13 home runs.

A good-contact hitter, Rose Gacioch only struck out 162 times in almost 3,000 career at-bats, and she ranks eight in the AAGPBL All-Time list with 352 runs batted in. As a pitcher, she won 92 games and lost 60 in 174 appearances. Her skill as an overhand pitcher led to the league’s changing its rules in 1947 to allow overhand pitching. She achieved four league championships and made the All-Star Team in 1951, 1952 and 1953. She retired from baseball after the league disbanded in 1954. Rose Gacioch died in Clinton Township, Michigan, at the age of 89.
