Lotte's professional baseball camp, which is being held on Ishigaki Island in Okinawa Prefecture, will enter its second season from the 7th. Rookie pitcher Otani was drafted second in last year's draft by the Toyama Thunderbirds of the independent league.
Otani is a right-handed pitcher with a powerful fastball that can reach a maximum of 159km/h. Haruya Tanaka, who is 19 years old and is in his second year as a pro, also took to the plate batting and threw 20 pitches.
