Ronel Blanco is enjoying an outstanding rookie season in the major leagues. He began with a bang, pitching a no-hitter on April 1, and has since maintained a 3.03 ERA, ranking as the second-best in the American League just behind Detroit's Tarik Skubal, who is leading the AL Cy Young race.
Blanco has also recorded a 1.09 WHIP and a remarkable .188 batting average against. Similar to his teammate Valdez, Blanco doesn't rely on overpowering fastballs; his fastball run value is in the 32nd percentile, and his average fastball velocity of 93.4 mph is in the 38th percentile.
However, like Valdez, Blanco's success in 2024 is largely due to his breaking pitches, with his breaking run value ranking him in the 100th percentile among pitchers. His slider, his second most-used pitch, has limited hitters to a .185 average and induced a whiff on 32.5% of swings. His least utilized but most effective pitch, the curveball, has held batters to a .063 average and achieved a 40.6% whiff rate.
Despite the Astros starters leading MLB in August with a 5.5 fWAR and a 2.59 ERA, Blanco experienced one of his less impressive months. Over five starts in August, he recorded a 4.07 ERA and a 1.48 WHIP, marking his second consecutive month with an ERA over 4.00, following a 4.40 ERA in July.
Blanco's situation might mirror that of Verlander, suggesting he has a definite role in the Astros’ postseason plans. However, given his recent performance and the strong form of his rotation peers, it's uncertain whether he'll serve as a starter or assume a long-relief, swingman role from the bullpen in the playoffs.
