Koo showed off his athleticism with one of the top 60-yard dash times of the day at 7.07 seconds. He also had the best pop time of the day at 1.97 seconds, using his strong and accurate arm with a quick release. Koo can also handle the bat with a short and compact swing geared for hard line drive contact. Overall, Koo had a solid day who identified himself as a complete player with athleticism.
