'Big Z' is the nickname of Croatian basketball player Zvonimir Ivisic
Big Z is the nickname of Croatian basketball player Zvonimir Ivisic, who was born in Vitez, Bosnia and Herzegovina, on 9 August 2003. Standing at 7 feet 2 inches tall, Ivisic is an imposing presence on the court and has been playing basketball since he was 14 years old when he moved to Šibenik, Croatia.
Ivisic's talent was first recognised when he played for the Croatia national under-16 basketball team in the 2019 FIBA U16 European Championship. He averaged 13.9 points and 6.9 rebounds in that tournament, and his performance led to him being invited to the 2022 NBA Combine. Ivisic has also played for SC Derby of the Montenegrin Basketball League and the ABA League from 2020 to 2023.
In 2023, Ivisic committed to play college basketball in the United States for the University of Kentucky, joining the Kentucky Wildcats. However, he encountered eligibility issues with the NCAA, which prevented him from playing until halfway through the Wildcats' season. Despite this setback, Ivisic made a strong collegiate debut on January 20, 2024, contributing 13 points, five rebounds, two assists, three blocks, and two steals in a 16-minute appearance against Georgia, which ended in a 105-96 victory for his team.
Following his time with the Kentucky Wildcats, Ivisic transferred to the University of Arkansas, playing for the Arkansas Razorbacks. He then moved on to play for the Illinois Fighting Illini of the Big Ten Conference. Throughout his college basketball career, Ivisic has demonstrated his skills as a versatile player, capable of handling the ball and shooting from distance.

Ivišić was born in Vitez, Bosnia and Herzegovina, and moved to Šibenik, Croatia, when he was 14 years old. He played for SC Derby of the Montenegrin Basketball League and the ABA League from 2020 to 2023. During this time, he also represented Croatia in international youth basketball, playing in the 2019 FIBA U16 European Championship and the 2023 FIBA U20 European Championship.
In 2022 and 2023, Ivišić declared for the NBA Draft but ultimately withdrew both times. He then committed to playing college basketball in the United States for the University of Kentucky. However, there were complications with his eligibility status, and the NCAA did not clear him to play until halfway through the Wildcats' season.

Ivisic rejoined the team after a trip home to Croatia
Zvonimir "Big Z" Ivisic, the 7-foot-2 basketball player from Vitez, Bosnia and Herzegovina, has rejoined the Kentucky Wildcats after a trip home to Croatia. Ivisic, who was born on 9 August 2003, moved to Šibenik, Croatia when he was 14 years old. He played for SC Derby of the Montenegrin Basketball League and the ABA League from 2020 to 2023. Ivisic's collegiate debut was on January 20, 2024, against Georgia, where he scored 13 points, five rebounds, two assists, three blocks, and two steals in 16 minutes during a 105–96 win.
Ivisic's return to the team is significant as many believed he would remain in Croatia due to the NCAA's delay in determining his eligibility status. John Calipari, the head coach of Kentucky Wildcats, stated that Ivisic had been struggling with the situation, which prompted the decision to send him home for the holidays. Despite the challenges, Ivisic rejoined his teammates before their trip to Florida for the SEC opener.
Ivisic's eligibility status with the NCAA remains unresolved at the time of his return. The hold-up is partly attributed to Ivisic having earned money while playing professionally in Croatia. His outstanding performance in the Montenegrin Basketball League and the ABA League raised questions about his amateur status, which is a key factor in determining NCAA eligibility.
While awaiting the NCAA's decision, Ivisic's presence with the Kentucky Wildcats provides optimism for the team and its fans. His height and skills as a center are valuable assets, and his return comes as a relief, especially with the team's current ranking in the AP Poll. Ivisic's dedication to rejoining the team demonstrates his commitment and perseverance in the face of adversity.
