Target Field has a target date. Outdoor baseball is tentatively set to return to Minnesota on April 12 when the Minnesota Twins play their 2010 home opener against the Boston Red Sox. The date was contained in a draft schedule for next season that recently was sent to teams and revealed Friday to The Associated Press. It was provided by a baseball official on condition of anonymity because Major League Baseball's central office asked that the schedule not be made public before it is finalized later this year.
