A catcher and an infielder
No. 2. — Darrell Porter, 1979. The starting catcher, Porter flew out to start the second, then came up one inning later with runners at first and second, and two outs. His grounder to third should have been the final out, but Mike Schmidt’s wild throw allowed Chet Lemon to score as Porter reached. Then, in the sixth inning of a 2-2 tie, Porter doubled Rick Burleson to third and Burleson scored on Bruce Bochte’s base hit. That put the AL ahead 6-5 but the NL eventually won 7-6. Porter Win Probability Added: +.236.
No. 1 — Cookie Rojas, 1972. The AL stars lost this game 4-3, but Rojas starred in the defeat. Rojas pinch hit for Rod Carew with two outs, a runner on first, and his team trailing 2-1 in the eighth inning, Rojas stunned NL pitcher Bill Stoneman with a rocket shot into the left field seats at Fulton County Stadium, thrusting the AL in front 3-2. Unfortunately, the NL tied the game with a ninth-inning run and won it 4-3 on Joe Morgan’s 10th-inning single. Rojas Win Probability Added: +.536.
