BP Chats

Date	Question	Answer
2009-04-20 13:00:00	Who is your favourite early season "sample-size all star" of all time? (Dylan from Toronto)	Wasn't early-season, but Kevin Maas. If I have to start from Opening Day, give me...what was the year Ruben Sierra started great for like the Mariners? 2002. (Joe Sheehan)

BP Roundtables

Date	Roundtable Name	Comment
2009-06-10 08:45:00	2009 Draft Coverage, Day Two	Nice nab in the 6th for the Tigers with shortstop Dan Fields, a local product who was expected to go much higher. Some bloodlines there, but even better ones with Texas' pick as they take Ruben Sierra's kid! (Kevin Goldstein)
