The Dodgers have introduced prized Japanese pitcher Roki Sasaki, who agreed to a minor league contract with a $6.5 million signing bonus. The 23-year-old right-hander whose fastball tops 100 mph was introduced Wednesday. He joins fellow Japanese stars Shohei Ohtani and Yoshinobu Yamamoto on the Dodgers in a signing many baseball executives long expected. Sasaki had until Thursday to finalize a contract. He donned a No. 11 jersey over his shirt and blue tie during a news conference outside the stadium.
