Randy Johnson, the 6-foot-10 left-hander known as "The Big Unit," carved a path of sheer dominance through Major League Baseball for 22 seasons. While his regular-season accolades—five Cy Young Awards, 4,875 strikeouts, a perfect game—are staggering, his playoff performances elevated him to a different echelon. In the crucible of October, Johnson transformed from a great pitcher into a postseason legend. His combination of a 100-mph fastball, a devastating slider, and an intimidating presence made him arguably the most unhittable pitcher in baseball history when the stakes were highest. This article unpacks the specific moments, games, and series that define Randy Johnson’s unparalleled playoff legacy.

Early Playoff Success with the Seattle Mariners

1995 American League Division Series: The Breakthrough

The Seattle Mariners made their first postseason appearance in franchise history in 1995, and Randy Johnson was the engine driving their unlikely run. After falling behind 0-2 to the New York Yankees in the best-of-five American League Division Series, the Mariners faced elimination. In Game 3 at the Kingdome, Johnson delivered what remains one of the greatest pressure-packed starts in postseason history.

He fired a complete-game shutout, allowing just three hits while striking out 12 Yankees batters over 7 innings (the game was shortened by rain after the top of the 7th, but it counted as a complete-game shutout under baseball’s rules at the time). The performance was a surgical display of power and precision—Johnson pumped fastballs at 98 mph and above, then froze hitters with a sweeping slider that dived under their bats. The Mariners won 7-0, staving off elimination and forcing a decisive Game 4.

But Johnson’s heroics were not done. In Game 5, with the series tied 2-2, Mariners manager Lou Piniella called on his ace in relief. Johnson entered in the eighth inning with the game tied and pitched three scoreless innings, allowing just one hit and striking out four. In the bottom of the 11th, Ken Griffey Jr. scored the winning run to send Seattle to the American League Championship Series—and Johnson fell to his knees on the mound, arms raised, in one of baseball’s most enduring images. That two-game performance cemented his reputation as a big-game pitcher and remains the defining moment of the Mariners’ 1995 postseason run.

1997 American League Division Series: Another Dominant Outing

Johnson returned to the playoffs with the Mariners in 1997, facing the Baltimore Orioles in the ALDS. In Game 1 at the Kingdome, he struck out 10 over seven innings, allowing only one earned run and earning the win. Though Seattle lost the series in four games, Johnson’s performance in that opener was vintage: he mixed high-octane fastballs with a biting slider, and the Orioles managed just three hits against him. It was a reminder that even when his team struggled, Johnson could single-handedly control a postseason game.

Dominance with the Arizona Diamondbacks

2001 National League Championship Series: The No-Hitter

Perhaps the single most dominant postseason start by any pitcher in modern baseball history occurred on October 9, 2001, in Game 2 of the National League Championship Series against the Atlanta Braves. After the Diamondbacks dropped Game 1 at home, Johnson took the mound at Turner Field needing to deliver a signature performance. He did more than that—he threw a no-hitter over eight innings. (The game officially ended after eight because the Diamondbacks scored in the top of the ninth and the Braves did not bat in the bottom half, but it is recognized as a postseason no-hitter, albeit a shortened one.)

Johnson struck out 11 Braves and walked only two. He faced 28 batters and retired 25 of them without a hit. The Braves’ best chance came in the fourth inning, when a soft liner to right-center nearly fell in, but center fielder Steve Finley made a sliding catch. Johnson’s slider was nearly unhittable; he generated 19 swinging strikes, a staggering number for a postseason game. The Diamondbacks won 4-0, tying the series and shifting all momentum in their favor. That start is often cited as the greatest single-game performance by a pitcher in National League Championship Series history.

2001 World Series: Legend Against the Dynasty

The 2001 World Series pitted the Arizona Diamondbacks—an expansion franchise in only its fourth season—against the three-time defending champion New York Yankees. Johnson was the centerpiece of Arizona’s rotation, and he delivered performances that would earn him the World Series Most Valuable Player Award.

Game 2: Dominance in the Desert

In Game 2 at Bank One Ballpark, Johnson faced a Yankees lineup that had crushed opponents with a mix of power and patience. He allowed only one earned run over seven innings, striking out 11 and walking just one. His fastball touched 101 mph in the eighth inning, even as his pitch count climbed past 100. The Diamondbacks won 4-0, evening the series at one game apiece. Johnson’s presence on the mound was so commanding that Yankees hitters later admitted they felt overmatched by his combination of velocity and movement.

Game 6: A Masterpiece Under Pressure

With the Diamondbacks trailing three games to two and facing elimination in Game 6 at Yankee Stadium, Johnson again took the ball. On three days’ rest, he pitched seven innings of one-run ball, striking out 11 and walking only one. He left with a 2-1 lead, but New York tied the game in the eighth after he exited. Arizona eventually won in extra innings to force Game 7. Johnson’s performance in Game 6 was arguably even more impressive than his Game 2 start, given the hostile environment, the short rest, and the must-win situation.

Game 7: The Unforgettable Relief Appearance

With the World Series on the line in Game 7, Diamondbacks manager Bob Brenly made a bold decision. After Johnson started and won Game 6, he asked for the ball again. Brenly started Curt Schilling, but after the Yankees built a 2-1 lead in the sixth inning, Johnson was summoned from the bullpen. Over four innings of relief, Johnson allowed just two hits and struck out five. He retired the final nine batters he faced, setting the stage for the dramatic ninth-inning rally. When Luis Gonzalez’s bloop single scored the winning run, Johnson had pitched in three of the last four games, earning a win in Game 7 and securing the World Series MVP trophy. His combined line in those three outings: 19 innings, 5 hits, 1 earned run, 27 strikeouts, and a 0.47 ERA.

Playoff Highlights and Awards

Beyond the 2001 postseason, Johnson compiled a career playoff résumé studded with remarkable achievements:

  • World Series MVP (2001) — The only pitcher in modern baseball history to win two games and a save in a single World Series.
  • Two ALDS complete games — One with Seattle (1995) and another with the Diamondbacks (2002, a 1-0 complete-game victory over the St. Louis Cardinals).
  • 30 career postseason strikeouts in a single series (2001 World Series), tied for the third-most in a single World Series.
  • Postseason no-hitter — The only no-hitter in NLCS history, and one of only two postseason no-hitters ever (the other being Don Larsen’s perfect game in 1956).
  • Career postseason ERA of 2.52 over 121.1 innings, with 144 strikeouts and just 28 walks. His strikeout-to-walk ratio of 5.14 is among the best all-time in the playoffs.
  • Four separate playoff appearances with two different teams — Seattle (1995, 1997), Arizona (2001, 2002), and later a brief stint with the San Francisco Giants (2009 wild card game, though he appeared in relief and did not factor into the decision).

2002 National League Division Series: Another Complete Game Gem

Johnson returned to the postseason in 2002 with the Diamondbacks, facing the St. Louis Cardinals in the NLDS. In Game 2 at Bank One Ballpark, he threw a complete-game shutout, allowing just five hits and striking out six. The 1-0 victory gave Arizona a 2-0 series lead, but the Cardinals rallied to win Games 3 and 4 before Johnson started Game 5 on short rest. He pitched 6.1 innings, allowing two runs and striking out eight, but the Diamondbacks lost 3-2, ending their season. Despite the loss, Johnson’s ability to deliver complete-game performances on short rest showed his relentless durability.

Later Playoff Appearances and Final Legacy

Johnson’s later career included playoff appearances with the New York Yankees (2005, 2006) and the San Francisco Giants (2009). With the Yankees, he pitched in the 2005 American League Division Series against the Los Angeles Angels of Anaheim. In Game 3, he allowed two runs over six innings with six strikeouts, but the Yankees lost the game and eventually the series. That postseason was less dominant than his peak, but Johnson still posted a 3.00 ERA in his only start. In 2006, he pitched in the ALDS against the Detroit Tigers, allowing three runs in five innings and taking the loss.

His final playoff appearance came at age 45 with the San Francisco Giants in the 2009 National League Wild Card Game against the Colorado Rockies. Johnson entered in relief and pitched one scoreless inning, striking out one. It was a quiet coda to a legendarily loud postseason career, but it showed that even as an elder statesman, Johnson could still compete at the highest level.

Legacy and Impact

Randy Johnson’s playoff moments are not merely a collection of statistics—they are the foundation of a Hall of Fame narrative. He is one of only two pitchers in MLB history (along with Sandy Koufax) to produce multiple postseason complete-game shutouts and a no-hitter. His 2001 World Series performance is widely regarded as the most dominant individual performance in a Fall Classic since Bob Gibson’s 1967 tour de force. Johnson’s ability to elevate his game under the brightest lights made him a feared opponent and a beloved figure among fans.

His impact extends beyond the numbers. Johnson’s height, left-handed angle, and explosive delivery created a terrifying at-bat experience. Hitters often described his fastball as “heavy,” and his slider as “invisible” until it was too late. In the playoffs, that intimidation factor multiplied. Teams would game-plan around him, often loading their lineup with left-handed hitters only to see them flail helplessly. Johnson finished his postseason career with 144 strikeouts in 121.1 innings, a rate of 10.68 strikeouts per nine innings—the highest among any pitcher with at least 100 postseason innings.

Johnson’s playoff legacy also includes leadership and adaptability. He willingly pitched on short rest, moved to the bullpen when needed, and never complained about role changes. That selflessness was on full display in Game 7 of the 2001 World Series, when he answered the call to relieve after starting Game 6. His Hall of Fame plaque in Cooperstown highlights these postseason achievements, and the 2001 World Series ring remains one of the most iconic pieces of championship jewelry in baseball history.

In the end, Randy Johnson’s playoff performances are a masterclass in clutch pitching. He didn’t just perform in October—he owned it. From the rain-shortened shutout in Seattle to the no-hitter in Atlanta, from the World Series rescue in relief to the final strikeout at age 45, Johnson’s postseason is a lesson in excellence under pressure. His legacy as a clutch performer remains an essential part of his Hall of Fame career, inspiring generations of pitchers to believe that the bigger the moment, the harder they must throw.
