College Ball & Spring Training Are Underway

Jim Callis and Jonathan Mayo celebrate the beginning of the college season and the opening of Spring Training on the latest Pipeline Podcast. They begin by checking in on how top college prospects performed during the first weekend, including UCLA shortstop Roch Cholowsky (the projected No. 1 overall pick), Texas A&M outfielder Caden Sorrell and UC Santa Barbara right-hander Jackson Flora. They also stack up all-prospect teams of the best college and high school players in the 2026 Draft and see how they compare. Then they shift gears and discuss some of the biggest prospect news in Spring Training, such as Yankees righty Carlos Lagrange throwing 103-mph heat past Aaron Judge and Mariners infielder Colt Emerson's efforts to squeeze into the lineup of the defending American League West champions. As always, the guys conclude with a question from the listener mailbag, this time trying to determine which phenom they'll talk about the most on the podcast this year.
