The ByungHo Park experiment appears to be over. According to a person with direct knowledge, the disappointing slugger has asked the Twins for his release so he can return home to the Korea Baseball Organization. The Twins are expected to grant Park his release, but the person cautioned Sunday night that talks were ongoing and “it will be a while before it is all worked out.” The Nexen Heroes, for whom Park slugged 105 homers in his final two seasons and won a pair of league MVP awards before that, have agreed to pay the first baseman $1.4 million in U.S. dollars for 2018, according to the Seoul-based Yonhap News Agency. Park was due $6.5 million from the Twins over the next two seasons, including a $500,000 buyout on a club option in 2020. Without a buyout to offset the difference, Park could be leaving as much as $5.1 million on the table, although much of that difference could be made up with future earnings on and off the field in the KBO. “He’s a very proud man and he wants to play — not in the minor leagues,” a person who has worked closely with Park said Sunday night. Reports out of Seoul had Park walking away from his entire remaining obligation from the Twins, who have paid $18.35 million total so far for two seasons and 12 big-league homers. That scenario could be premature as the Twins, Park’s representatives and the KBO continue to discuss a number of details regarding the transaction. Signed to a four-year, $12 million deal that included an $12.85 million posting fee to the Nexen club, Park struggled with a wrist issue in the first half that season and managed to drive in just 24 runs in 62 games.
