Carmen Mlodzinski Bio
Carmen Alexander Mlodzinski, pronounced muh-JIN-ski, is an American professional baseball pitcher for the Pittsburgh Pirates of Major League Baseball (MLB). Born on February 19, 1999, in Hilton Head Island, South Carolina, he was selected by the Pirates with the 31st overall pick of the 2020 MLB Draft after a standout college career at the University of South Carolina. A right-handed pitcher, Mlodzinski has worked his way through the minor leagues and now serves as a versatile arm in the Pittsburgh rotation and bullpen.
Early Life and Background
Carmen Alexander Mlodzinski grew up in Hilton Head Island, South Carolina, where he attended Hilton Head Island High School. As a senior in 2017, he was named the South Carolina 4A Player of the Year, an honor that established him as one of the top amateur pitchers in the state. Although he was a draft-eligible prospect that summer, Mlodzinski informed professional scouts that he intended to honor his college commitment to the University of South Carolina, and he went undrafted in the 2017 MLB Draft.
His decision to attend college in his home state kept him close to the Lowcountry region while pursuing a higher level of competition. After graduating from Hilton Head Island High School, Mlodzinski enrolled at the University of South Carolina in Columbia, where he joined the South Carolina Gamecocks baseball program and began the next chapter of his pitching development.
Path to Baseball
At the University of South Carolina, Mlodzinski quickly transitioned into a starting role for the Gamecocks. As a freshman in 2018, he pitched 45 and two-thirds innings across 19 appearances and seven starts, posting a 3–6 record with a 5.52 ERA, 21 walks, and 43 strikeouts. The following year, as a sophomore in 2019, he earned the Gamecocks’ opening day starting assignment, signaling his importance to the program’s pitching staff.
His 2019 season was cut short by a foot injury suffered during his third start, but he returned that summer to pitch for the Falmouth Commodores of the Cape Cod Baseball League, where he posted a 1.83 ERA with 43 strikeouts against only five walks over 34 and one-third innings. Entering his redshirt sophomore season in 2020, Mlodzinski was regarded as a top MLB Draft prospect. He pitched to a 2.84 ERA over four starts before the season was halted by the COVID-19 pandemic.

The Pittsburgh Pirates selected Mlodzinski with the 31st overall pick of the 2020 MLB Draft, and he signed on July 2, 2020, for a $2.05 million bonus. Because the minor league season was canceled due to the pandemic, he did not appear in a professional game that year. In 2021, Mlodzinski made his professional debut with the Greensboro Grasshoppers of the High-A East, going 2–3 with a 3.93 ERA and 64 strikeouts over 50 and one-third innings across 14 starts, despite two stints on the injured list with shoulder issues.

At the time of his promotion, he had pitched 19 games for Indianapolis, recording a 3.16 ERA with 31 strikeouts and one save over 25 and two-thirds innings.
