You must complete the season with Garland leading the league in victories. To have him easily earn wins, try the following trick. In order for a starting pitcher to earn a victory, he must pitch at least five innings in a nine inning game (or four innings if you are playing a seven inning shortened game). Whether you a playing or managing the game and are winning, let your regular starter get two outs in the fifth inning (in a nine inning game) or two outs in the fourth inning (in a seven inning game), then bring in Garland. Even if he only gets one out and your team keeps the lead, he will qualify for the win. To be safe, you may want to let him pitch a full inning, but he will qualify by just getting one out. Do this throughout the season to let Garland rack up the wins and take a huge lead. In order to get the card you must play at least fifteen games in your season.
