Patrick Sandoval ParlayPlay MLB Pick: OVER 1.5 Walks Allowed

Matchup meets opportunity here. Sandoval has walked multiple batters in 10 straight outings, and if you look at his last four starts, his first-pitch strike rate is down at 47%, which is quite poor. Like most pitchers, Sandoval has pretty drastic numbers depending on if the count gets to 1-0 versus 0-1. This year, his walk rate sits at 3.3% through an 0-1 count, but through a 1-0 count, his walk rate soars to 20.3%. The Rays have been strong against left-handed pitching this month, but most notably in September, Tampa Bay has the eighth-highest walk rate (10.2%) against southpaws.

Randy Arozarena ParlayPlay MLB Pick: OVER 1.5 Total Bases

During Arozarena’s eight-game hit streak, he’s slashing .412/.459/.824 with four home runs, two doubles, 11 runs scored, 9 RBI, and a monstrous .412 ISO! In September, he has an .813 OPS and .364 wOBA against RHP, and he’ll take on Colorado’s Tomoyuki Sugano, who has allowed a .295 AVG and .500 SLG to RHP in 2026. Furthermore, when pitching at Coors Field, Sugano has surrendered a 5.64 ERA, 6.07 FIP, and 2.36 HR/9. Sugano has struggled of late, and Arozarena is seeing a beach ball at the plate.
