The Cardinals-Cubs matchup brings its own historic intensity, fueled by deeply rooted fan hostility and wild-card implications. The Cardinals enter the series with massive momentum following 23-year-old prospect Joshua Báez's historic MLB debut, where he became the first player ever to hit three home runs in his first three big-league at-bats, earning a rare standing ovation from rival fans.

Meanwhile, in the Padres-Guardians matchup, traders can back a surging Padres team that has reignited its fanbase by sweeping recent opponents and proving they are a resilient lineup that consistently finds ways to win.
