Andrew Miller - All his Strikeouts of his Postseason Career So Far ALDS, ALCS, World Series

On July 31, 2016, the Yankees traded Miller to the Cleveland Indians for Clint Frazier, Justus Sheffield, Ben Heller and J. P. Feyereisen. Miller's first save for Cleveland was in a 5−2 victory over New York at Yankee Stadium on August 6, 2016. He became the first pitcher to earn a save for and against the Yankees in the same season since 1988. Francona, now reunited with Miller as the Indians' manager, commented that he saw "a guy that is willing to pitch any inning." He deployed Miller in every inning from the fifth into extra innings, "in the highest stress situations," appearing before the eighth inning in nine of 26 games. With Cleveland, Miller completed 29 innings, allowed two walks, and struck out 46, posting a 1.55 ERA. His aggregate 2016 regular season included 12 saves, a 10−1 record, 1.45 ERA, 0.68 walks plus hits per inning pitched (WHIP),123 strikeouts and nine walks. He became the first major leaguer in history to record 120 or more strikeouts in a season while allowing fewer than ten walks. According to Brooks Baseball, opponents batted .159 against Miller's slider in 2016. He placed ninth in the AL Cy Young Award balloting, receiving one third place vote.The Indians swept Boston in the ALDS and Miller completed four innings in two appearances, permitting two hits, walking two and striking out seven. He played in two innings each of Games 1 and 2 in the American League Championship Series (ALCS) against the Toronto Blue Jays, he striking out ten of 12 batters faced. After striking out Kevin Pillar in the seventh inning of Game 2, he matched Phil Coke in the 2012 World Series as the only pitchers to strike out at least five consecutive batters in the postseason. Miller also became the first pitcher in major league history to strike out at least five batters each on consecutive days. Covering his first four appearances in the 2016 postseason, he struck out 17 in  7 2⁄3 innings.Miller recorded the final four outs of Game 3, striking out three in a 4−2 win, for his first career postseason save.[63] In Game 5, he completed  2 2⁄3 innings as the Indians won the ALCS. He was named ALCS Most Valuable Player (MVP), having completed  7 2⁄3 scoreless innings, allowing three hits, no walks and striking out 14. His strikeout total set an ALCS record for relievers. He also was credited with three holds and one save. At that point, he had completed 20 scoreless innings to begin his playoff career. In Game 3 of the World Series against the Chicago Cubs, Miller was credited with his first World Series win in a 1–0 victory. After striking out three of four batters faced in  1 1⁄3 innings, he reached 15 consecutive scoreless innings in the 2016 playoffs, surpassing Mariano Rivera and Goose Gossage to set the record for relief pitchers in a single postseason. In Game 4, he struck out two Cubs hitters, bringing his 2016 playoff total to 29, and surpassing Francisco Rodríguez' total of 28 in the 2002 postseason for the all-time record among relievers in a postseason. Another strikeout record Miller set was to strike out at least three batters each in seven different appearances, all in the 2016 postseason, and more than other MLB reliever. Dexter Fowler homered off Miller in Game 5, ending his scoreless streak at 17 innings in the 2016 playoffs and  24 1⁄3 to commence his postseason career. In Game 7, Miller allowed five batters to reach base and two runs to score in  2 1⁄3 innings as the Indians lost the game and Series. In spite of finally succumbing in pivotal Game 7 to the Cubs' offense, Miller was named the 2016 Esurance MLB/This Year in Baseball Award winner for Best Postseason Major Leaguer.

I have been in many postseasons and hadn't seen anybody dominate like Andrew Miller. Not even the great Mariano Rivera I saw having as much success as Andrew Miller, overpowering hitters.
