With playoff baseball comes the inevitable debates about who the greatest postseason performer was. This has been especially true in lieu of Josh Beckett and Curt Schilling's recent performances in the World Series.

Many people are familiar with some of the best postseason hurlers, but what about some other, less heralded pitchers? Are there guys out there who may have flown a bit under the radar? In fact, there are a number of them. While none of these guys had the extensive impact of a Bob Gibson or Mariano Rivera, they still delivered clutch performances throughout their postseason careers*.

Ken Dayley, St. Louis Cardinals
If I were to ask you who in postseason history had the best WHIP (0.58), allowed the least number of hits per 9 innings (2.61) and the fourth best ERA (0.44), your first answer might not be Ken Dayley, but that's the correct answer.

Dayley was a lefthanded reliever for the Cardinals who pitched in both the 1985 NLCS and World Series, and the 1987 NLCS and World Series. He never pitched more than 2 2/3 innings, but he was an important part of the bullpen, picking up 5 saves even though Todd Worrell was the main closer. In 20 2/3 postseason innings, Dayley gave up just 1 run.

Dave Dravecky, San Diego Padres, San Francisco Giants
Just who is Dave Dravecky? Well, he was a hurler who pitched in the 1984 NLCS and World Series for the Padres and the 1987 NLCS for the Giants. Dravecky had entirely different roles for those teams, however.

First, let's look at some numbers. Dravecky possess the third best ERA (0.35) in playoff history, and the second best WHIP (0.66). In Dravecky's postseason career, he found himself relieving for the Padres, and going multiple innings every time. In 10 2/3 innings of relief for San Diego, he didn't give up a single run, walked just one batter, allowed only 5 hits, and struck out 10.

Then, Dravecky went on to starting for the San Fransicso Giants. In the '87 NLCS, he threw a complete game, 2-hit shutout against St. Louis in game 2, and followed that with a 6 inning stint where he struck out 8, allowed 5 hits and the only run of his postseason career in a 1-0 loss.

Sterling Hitchcock, San Diego Padres, New York Yankees
Surprised? Yeah, me too. However, Hitchcock is one of only eight pitchers to have a perfect win-loss record in the postseason, at 4-0. Not to mention the fact that he has the third best K/9 ratio in postseason history. Hitchcock struck out 12.03 batters per 9 innings pitched, which is over 5 strikeouts per 9 more than his regular season average.

Hitchock appeared in 9 games, and he was a starter in 4 of those games. And in those starts, Hitchcock was 3-0. He struck out 32, allowed only 3 extra-base hits, had a 1.23 ERA and held opponents to a .195 batting average and .287 on-base percentage.

Others
Harry Breechen, St. Louis Cardinals: 1943, '44, '46 World Series - 3 complete games, 4 wins, 0.87 ERA, 3 total earned runs allowed.

John Rocker, Atlanta Braves, Cleveland Indians: 1998, '99, 2000, '01 NL/ALDS, NLCS, World Series - 20 games, 0.00 ERA, 4.35 hits/9 allowed, 11.32 K/9.

Blue Moon Odom, Oakland A's: 1972, '73, '74 ALCS, World Series: 1.07 ERA in 42 innings, 5 total earned runs allowed, 4.71 hits/9 allowed.

Obviously, this is but a small sample size of pitchers that have put up very good postseason numbers. There are many more that have performed well, but these are a few that people may not have known about.
