Mostly, I used the Wins Probability Added metric (WPA) to help ascertain which players performed in the higher leverage situations. In other words, if the Miami Marlins are winning, 6-0, a plate appearance doesn’t count as much. Conversely, an at bat with two on and two out in the bottom of the 13th has a very high leverage.
Miami’s entire bullpen and every position player got into at least one game. Every starting pitcher currently on the roster also played at least one game. Famously, Odrisamer Despaigne appeared as both a reliever and as a starter. Brian Ellington, who was recently sent down, didn’t appear in the series.
