Nippon Ham Fighters young star pitcher Darvish Yu (21) got some good news before the start of what should be a key season for him. He announced on his blog yesterday that his wife, actress Saeko (23), gave birth to a baby boy. The two took the media by surprise in August of last year when they told the world about their engagement and Saeko’s pregnancy in rapid succession. The young half-Iranian pitcher made his breakthrough when the Fighters won the Japan Series in 2006, though they failed to defend that title last year, losing the 2007 series to the Chunichi Dragons. Popular not just for his good looks, Darvish is considered one of the best young pitchers in Japan. He’ll be on the Japanese team at the Olympics this summer and a year from now he may well lead the team at the Baseball World Championships. And then the inevitable comparisons to Matsuzaka Daisuke and his move to the Major Leagues.
