Steve Buchanan strongly recommends betting Yordan Alvarez to exceed 1.5 total bases against Luis Castillo. Buchanan emphasizes Castillo's significant platoon splits, noting left-handers posted a .361 wOBA and slugged 18 of the 25 homers he allowed last season, a trend continuing this season with lefties' early .355 wOBA. Alvarez matches well against Castillo's primary pitches (fastball, slider), which account for 62% of Castillo's pitch arsenal. Alvarez has thrived against these pitches since last season with a .364 wOBA against fastballs and a .339 wOBA against sliders, positioning him favorably to cover his total base prop.
