BaseLinePro - Version 3.0 BaseLinePro is a Baseball Lineup Program that helps coaches quickly produce Batting and Fielding Lineups. BaseLinePro is particularly useful for coaches with large Team Rosters, or recreational leagues with minimum infield-play rules for each player. BaseLinePro can be configured for any baseball, softball, or T-ball league. Coaches enter their Roster and Game Setup once at the start of the season, then create Batting and Fielding Lineups using the mouse. Players marked as Absent are automatically moved to the bottom of the lineups.
