Hokkaido Nippon Ham Fighters ace Shohei Otani has just one win and a 3.34 ERA after eight starts, but former Fighters ace Yu Darvish says it's too early to worry about the 21-year-old right-hander.

Darvish, now a star pitcher for the Texas Rangers, recently took to social media to voice his opinion.

"Anybody can have a bad season," Darvish was quoted as saying in a report by Daily Sports. "It's way too early to say if it's good or bad in Otani's case because it's not even June yet."
