After spending most of the season sidelined with a shoulder impingement, Roki Sasaki emerged as an unexpected October hero for the Los Angeles Dodgers, showcasing electric relief performances in the NL Division Series. His dominance was highlighted in Game 4 against the Philadelphia Phillies, where he delivered three perfect innings in an 11-inning, 2-1 victory, securing the Dodgers' place in the NLCS. Manager Dave Roberts lauded his appearance as "one of the great all-time" relief outings, and Sasaki was celebrated by teammates. His resurgence began on September 8th in Oklahoma City, where he rediscovered his explosive delivery and fastball velocity, hitting over 100 mph. Following this, he agreed to a temporary bullpen role, a move that drastically improved his playoff chances. Sasaki saved Games 1 and 2 of the NLDS and pitched three critical innings in Game 4, retiring the heart of the Phillies' lineup. Teammate Tyler Glasnow called him "unbelievable." Beyond his physical recovery, Sasaki regained confidence, displaying a new, aggressive demeanor on the mound. While currently the ace of the bullpen, the Dodgers view him as their future staff ace, with Roberts stating he's "just scratching the surface" of his special talent.
