My Take

Mario Santiago is the kind of professional whose value shows up most clearly when he pulls on the Puerto Rico jersey for the World Baseball Classic. International tournament pitchers carry a unique pressure, representing an entire island's baseball-mad passion, and that takes a special temperament. Players like him keep the global game vibrant outside the Major League spotlight, grinding through pro leagues and showing up when their country calls. I have a soft spot for steady, journeyman starters who give their teams quality innings without fanfare. The WBC is richer for arms like his, and Puerto Rican baseball runs deep because of players who answer the call.
