The Guardians, known for their elite pitching rotation and league-best contact rate, faced a Red Sox lineup rejuvenated by rising stars and aggressive offensive metrics. Let’s break down the key statistics and stories that emerged from this marquee matchup.
Cleveland Guardians: Player Performance Breakdown
Jose Ramirez – The Heart of the Offense
Jose Ramirez continues to be the cornerstone of Cleveland’s batting lineup in 2025. Across the four-game series, Ramirez recorded a .357 batting average, 2 home runs, and 6 RBIs. His on-base plus slugging (OPS) stood at an impressive 1.021, underlining his ability to combine power and plate discipline.
Ramirez’s expected batting average (xBA) and hard-hit percentage both ranked in the top 10 percentile in the league according to Baseball Savant. His clutch three-run homer in Game 2 turned the tide for Cleveland, reaffirming his status as one of MLB’s most dependable middle-order hitters.
Steven Kwan – The Contact Machine
Steven Kwan remains one of the league’s elite contact hitters. In this series, he posted a .389 average and reached base in all four games. His on-base percentage (.455) and defensive contributions in left field once again showcased his versatility.
Kwan’s approach — emphasising pitch selection and short-swing mechanics — mirrors the Guardians’ offensive philosophy. Cleveland led MLB in lowest strikeout rate (18.4%) through August 2025, and Kwan is the primary reason behind it.
Tanner Bibee and Shane Bieber – Pitching Precision
The Guardians’ pitching remains their biggest asset. Tanner Bibee and Shane Bieber both delivered quality starts. Bibee recorded 9 strikeouts in 6 innings in Game 1, allowing just one earned run, while Bieber, returning to form after injury, pitched 7 scoreless innings in Game 3.
Bibee’s advanced metrics — 3.12 ERA, 3.05 FIP, and a WHIP of 1.07 — have positioned him among the AL’s top young pitchers in 2025. Bieber’s pitch efficiency and improved fastball spin rate highlighted Cleveland’s pitching development success.
Bullpen Depth
The Guardians’ bullpen, led by Emmanuel Clase, remained clinical. Clase converted his 28th save of the season in the series finale, boasting a 1.48 ERA and an average fastball velocity of 99.3 mph. Middle relievers Eli Morgan and Sam Hentges provided stability, combining for 5 shutout innings across the series.
Boston Red Sox: Player Performance Breakdown
Rafael Devers – Power and Consistency
Rafael Devers continues to be Boston’s offensive anchor. In the 2025 Guardians series, Devers hit .333 with 3 home runs and 7 RBIs. His barrel rate (15.2%) and expected slugging (xSLG) of .545 have been among the best in the AL East.
His ability to hit both left- and right-handed pitchers makes him a crucial component in Boston’s lineup. Devers’ exit velocity average of 92.1 mph also underscores his power consistency this season.
Triston Casas – Breakout First Baseman
Triston Casas, now in his breakout third season, has become a major power threat for Boston. He posted a .321 average in the series with a 1.042 OPS and 2 home runs. Casas’ plate discipline and launch angle adjustments have dramatically improved his production, turning him into a future All-Star candidate.
Brayan Bello and Kutter Crawford – Emerging Pitching Leaders
Boston’s pitching staff, once a weakness, has seen significant progress. Brayan Bello, with a sinker-changeup mix, limited Cleveland to 2 earned runs over 7 innings in Game 1. His 2025 ERA sits at 3.38, with a ground-ball rate of 55%, reflecting efficiency.
Kutter Crawford also showcased improved command, posting 8 strikeouts in his start. His 3.45 ERA and 1.18 WHIP make him a reliable mid-rotation starter in a team aiming for stability.
Kenley Jansen – Veteran Reliability
Closer Kenley Jansen remains a key presence in Boston’s bullpen. The veteran recorded a crucial save in Game 2, increasing his total to 25 on the season. Despite age and reduced velocity, Jansen’s cutter movement and high-leverage poise continue to deliver results.
