You buy Baseball Mogul and take control of the Los Angeles Angels, hoping to build a dynasty around Mike Trout and young arms like Jaime Barria and Jose Suarez. But when you open trade talks with other GMs, they ask for players you aren't willing to give up. Baseball Mogul 2019 eliminates this problem by letting you flag any player as off-limits in trade talks.
Each player's Trading Block Status is shown on their Scouting Report under their photo. To elminate all trade offers for a player, click on the status and then select "Won't Trade". To increase offers for a player, choose "On The Block".
