The South Korean pitcher who dreamt of becoming big in the baseball world has come clean—albeit partially—on the charges of illegal overseas gambling filed against him.

Oh Seung-Hwan, a relief pitcher fothe Hanshin Tigers, was called to the Seoul Central District Prosecutor’s Office early Wednesday morning to investigate whether he “gambled some hundreds of millions of won in Macau in November 2014,” Yonhap News reported.

During the interrogation, which lasted for five hours, Oh reportedly admitted that he borrowed chips worth “some hundreds of millions of won,” but said the number of times he gambled and the amount he wagered were “insignificant.”

Prosecutors, however, were able to secure Oh’s entry log to the casino and records of his money transaction with the gambling house owner, who was only identified as Lee, according to the report.
