Alexander David Kirilloff (born November 9, 1997) is an American professional baseball outfielder for the Minnesota Twins of Major League Baseball (MLB). He made his MLB debut in 2020.
Kirilloff was selected 15th overall in the first round by the Minnesota Twins in the 2016 MLB draft. Kirilloff spent his first professional season with the Elizabethton Twins where he hit .306/.341/.454 with seven home runs, nine doubles, and 33 RBIs in 55 games, which earned him Appalachian League MVP honors.
His season was cut short with a partial ligament tear in his elbow, and he tried to avoid surgery, receiving platelet-rich plasma therapy. It was eventually deemed necessary that Kirilloff undergo Tommy John surgery, forcing him to miss all of 2017.
He returned in 2018 with the Cedar Rapids Kernels before being promoted to the Fort Myers Miracle in June. In 130 games between the two clubs, he slashed .348/.392/.578 with twenty home runs and 101 RBIs.
Kirilloff began 2019 with the Pensacola Blue Wahoos on the injured list with a wrist injury. For the season, he played in 94 games, slashing .283/.343/.413 with nine home runs and 43 RBIs. He was selected to play in the Arizona Fall League for the Salt River Rafters following the season.
On July 21, 2021, it was announced that Kirilloff would undergo season-ending surgery to repair a torn ligament in his right wrist.
