The Top 10 American League Pitchers for 2025

The 2025 MLB season is filled with dominant arms in the American League, featuring a mix of veteran aces and young stars. These pitchers have established themselves as the best in the AL based on their 2024 season performances, ranking highly in ERA, WHIP, and strikeouts. Here’s a closer look at the ten best-starting pitchers in the AL heading into 2025.

1. Tarik Skubal (Detroit Tigers)

• ERA: 2.39 | WHIP: 0.92 | Strikeouts: 228
• Skubal emerged as the premier pitcher in the American League in 2024, winning the AL Cy Young Award after leading the league in ERA and strikeouts. His electric fastball and devastating slider kept hitters off balance all season. Skubal’s ability to generate swings and misses while limiting hard contact has made him the ace of Detroit’s staff. Heading into 2025, he’s expected to build on his dominance and continue leading a young and improving Tigers rotation.

2. Logan Gilbert (Seattle Mariners)

• ERA: 2.49 | WHIP: 0.95 | Strikeouts: 215
• Gilbert has been a model of consistency for the Mariners, finishing the 2024 season with an impressive ERA and WHIP. His durability and ability to pound the strike zone have made him one of the most reliable starters in the AL. He pairs a mid-to-upper 90s fastball with a devastating slider, making him a tough matchup for any lineup. As the Mariners aim for another playoff push, Gilbert remains a key piece of their rotation.

3. George Kirby (Seattle Mariners)

• ERA: 2.68 | WHIP: 1.02 | Strikeouts: 198
• Known for his elite command, Kirby finished 2024 with one of the best WHIPs in baseball, allowing very few walks while still missing bats. His ability to attack hitters with precision while maintaining high velocity has solidified him as a top-tier starter. As Seattle continues to develop one of the best young rotations in baseball, Kirby’s ability to consistently limit baserunners will be crucial to their success.

4. Framber Valdez (Houston Astros)

• ERA: 2.91 | WHIP: 1.16 | Strikeouts: 169
• Valdez has long been a ground-ball machine, relying on his heavy sinker and sharp-breaking curveball to induce weak contact. His strong ERA and WHIP numbers make him one of the most dependable arms in the Astros’ rotation. With Houston aiming for another deep playoff run, Valdez’s ability to eat innings and control the pace of the game will remain invaluable.

5. Cole Ragans (Kansas City Royals)

• ERA: 3.14 | WHIP: 1.14 | Strikeouts: 223
• Since being traded to Kansas City in 2023, Ragans has developed into a frontline starter, finishing 2024 with an excellent strikeout rate and solid ERA. He features one of the most explosive fastballs among AL lefties, complemented by a nasty slider. The Royals may not be contenders yet, but Ragans gives them a legitimate ace to build around as they continue their rebuilding process.

6. Dylan Cease (Chicago White Sox)

• ERA: 3.47 | WHIP: 1.07 | Strikeouts: 224
• Cease remains one of the most electric pitchers in baseball, finishing 2024 with an elite strikeout total. While he still struggles with command at times, his dominant fastball-slider combination makes him a nightmare for opposing hitters. The White Sox’s struggles in the standings haven’t overshadowed Cease’s individual brilliance, and if he finds more consistency in his control, he could return to Cy Young contention.

7. Gerrit Cole (New York Yankees)

• ERA: 3.41 | WHIP: 1.05 | Strikeouts: 210
• The veteran ace of the Yankees rotation, Cole battled some injuries in 2024 but still put together a solid season. He continues to be one of the most dominant power pitchers in the game, utilizing a high-velocity fastball and sharp-breaking slider. As the Yankees seek to return to World Series contention, Cole’s ability to stay healthy and provide ace-caliber innings will be key to their success.

8. Garrett Crochet (Boston Red Sox)

• ERA: 3.58 | WHIP: 1.12 | Strikeouts: 175
• Crochet made the transition from bullpen arm to starter and thrived in 2024. The left-hander has a high-velocity fastball and a sharp breaking ball that make him an intimidating presence on the mound. If he continues refining his command, he could establish himself as one of the top left-handed starters in the league.

9. Tanner Bibee (Cleveland Guardians)

• ERA: 3.60 | WHIP: 1.15 | Strikeouts: 180
• Bibee’s impressive rookie campaign in 2024 saw him quickly prove he belongs at the big-league level. He displayed excellent control and a mix of solid off-speed pitches, making him one of the most promising young arms in the AL. Cleveland has built a strong rotation over the years, and Bibee’s continued development will be essential in keeping them competitive in the AL Central.

10. Bryce Miller (Seattle Mariners)

• ERA: 2.94 | WHIP: 0.98 | Strikeouts: 171
• The third Mariners pitcher on this list, Miller has rapidly risen through the ranks with his electric fastball and ability to generate swings and misses. His breakout 2024 season solidified himself as a crucial part of Seattle’s deep and talented rotation. If he continues to refine his secondary pitches, he could take another step forward in 2025.

Each of these pitchers brings something unique to their respective teams, whether overpowering velocity, elite command, or the ability to consistently generate weak contact. With so much talent in the American League, the 2025 season should feature plenty of thrilling pitching performances.
