"All of the speculation surrounding Japanese phenom Yu Darvish is expected to end on Monday night.

Darvish's agent, Don Nomura, sent out a tweet on Monday morning saying an announcement will be made on the winning bid late Tuesday morning in Japan, or around 9 p.m. ET on Monday.

SI.com has reported that the bid for the right-handed Darvish, currently with the Hokkaido Nippon-Ham Fighters, exceeds the Red Sox's $51.11 million bid for Daisuke Matsuzaka in 2006 as the highest in the history of posting of Japanese players. "
