2. Pitcher Breakdown
Pitching Matchup: Brad Lord vs. Framber Valdez
Brad Lord (WSH):
Brad Lord utilizes a diverse arsenal: Four-Seam Fastball (56% usage, 95.0 mph), Slider (18% usage, 85.0 mph), Sinker (15% usage, 94.9 mph), Changeup (11% usage, 85.8 mph), and a seldom-used Slurve (0% usage, 82.3 mph). This mix indicates a velocity-heavy approach with a focus on fastballs and sliders. The Astros lineup has averaged .276 this season but projects a lower xBA of .235 against Lord's arsenal, indicating potential issues with his velocity and pitch mix.
Framber Valdez (HOU):
Framber Valdez features a dynamic mix: Sinker (44% usage, 94.3 mph), Curveball (34% usage, 79.5 mph), Changeup (19% usage, 89.9 mph), with minimal usage of Slider (2% usage, 84.3 mph) and Four-Seam Fastball (2% usage, 93.5 mph). Valdez is a pitch-mix artist, effectively using his off-speed pitches to keep hitters off-balance. The Nationals lineup has a season average of .254 but projects to .246 against Valdez's arsenal, suggesting a slight disadvantage against his diverse pitch mix.
