Select an open position on the left and players who can fill that role will appear on the right (or below on mobile). Select a player and they'll be added to your roster along with their 2020 salary and luxury tax hit. Clicking on that spot again will remove them, or you can select a new player and they'll fill it. Trade candidates are included sans prospect cost, so choose what you think is reasonable. Luxury tax number automatically includes $17,250,000 for minor leaguers on the 40-man roster and player benefits. Be careful, the Lerners don't want to exceed the luxury tax and won't be happy if you try to!
