Growing up in Boston, baseball wasn't a hobby so much as the background hum of every summer — the radio on the porch, the slow unspooling of a 162-game season measured out across the warm months. I loved the rhythm of it long before I understood the numbers, and when I finally dug into the data it only deepened how the daily grind actually works. My picks lean heavily on starting-pitching matchups, bullpen workload heading into a series, park factors, and how a lineup splits against left and right-handed pitching. Baseball quietly rewards people who think in probabilities across a long schedule rather than reacting to one bad night, and that mindset shapes the way I treat run lines and totals far more than any single result does. Ten years in, I've come to love how honest the sport is over a full season and how cruel it can be on any single evening — a great read can die to one swing in the ninth. So I stay disciplined about process, keep my expectations fair, and show the reasoning instead of selling a guarantee. — Erin Callahan
