The Chiba Lotte Marines took hard-throwing high school pitcher Roki Sasaki in NPB's amateur draft Thursday after four teams selected the teen talent who has been on the radar of major league clubs.

The 17-year-old Sasaki's fastball has been clocked in competition at 160 kph and as high as 163 kph in a national team tryout camp.

"He's an extraordinary pitcher," Marines manager Tadahito Iguchi said after drawing the winning lot. "It's scary to think how far he might go. He was the best player available and now it's incumbent on us to nurture his potential."
