They have not faced each other in the Major Leagues but Aoki remembers going against Darvish in Japan. How did he do?
"So-so," Aoki said. "He was in a different league so I didn't really face him too much."
Aoki played from 2004-11 for the Tokyo Yakult Swallows in the Japan Central League; Darvish had a seven-year career with the Hokkaido Nippon-Ham Fighters of the Pacific League.
"It seems like he's gotten better since he came over here, too," Aoki said.
Darvish has faced the Royals twice in regular-season competition with a 1-0 record and a 1.93 ERA (three runs in 14 innings). Omar Infante, coming over from the Tigers, has had the most success of the Royals regulars against Darvish, with three hits in six at-bats.
