Brian Howard hammered Fernando Tatis Jr. props against Jack Flaherty, recommending total bases, RBI, and home‑run ladders. In 13 career plate appearances versus Flaherty, Tatis is 7‑for‑10 with two bombs, four doubles, two walks, and only one strikeout (.700 AVG, 1.700 SLG). Digging deeper, Howard matched Flaherty’s current pitch mix—43.8% four‑seam, 29.6% slider, 20.4% curve—against Tatis’ 2025 run values: +4 on fastballs (xBA .368, 61.5% hard‑hit, K‑rate <10%), +5 on sliders (xBA .387, 50% hard‑hit), and even the ‘worst’ pitch, the curve, shows a +1 run value and .303 xBA. Because Flaherty leans on a four‑seamer nearly half the time, Howard expects Tatis to see multiple hittable heaters and at least one hanging slider, making Tatis a prime target for 2+ total bases or an RBI at plus money in DFS and betting markets.
