Reggie Jackson (1971-1975, 1977-1978, 1980-1982, 1986): If there was one hitter you really didn’t want to face in the 70’s and early 80’s in the playoffs, it was Mr. October, Reggie Jackson. I really only need to point out his three homerun game and the fact that his strikeout to pitcher Bob Welch is considered a Top 20 WS moment by many to show his playoff dominance, but his stats help too. In the 5 WS he played in (he was a part of 6 WS teams, but he was hurt for one), he hit .357 with a .457 OBP and .755 slugging percentage over 27 games. He had ten HR in World Series games, including five in the 1977 WS, leading to a 1.250 slugging percentage. He was a key player in four World Series victories and won 11 of 17 post-season series. The two-time WS MVP is the symbol of World Series dominance to this day.

Curt Schilling (1993, 2001, 2002, 2004) - While Schilling has often been an above average regular season pitcher, he turns it up in the postseason. His teams are 7-2 in post-season series, 2-1 in World Series, including the first title for the Diamondbacks and the first for the Red Sox in 86 years (on a bloody sock no less). His career 2.06 playoff ERA is enhanced by 109 1/3 postseason innings. He has averaged about a strikeout per inning in his postseason appearances and has been part of two historic World Series runs.
