Rays rookie Jake Mangum headlines a September Chicago swing that doubles as a speed-and-family story. The switch-hitter, who debuted with Tampa Bay after being drafted by the Mets in 2019, is at .296 with 23 steals across 99 games, and he's set for a run of games against the White Sox and Cubs that could boost stolen-base opportunities.

The trip pairs Mangum’s ascent with his father John Mangum Jr.’s Bears legacy and an alumni night at Soldier Field, giving fantasy managers a vivid lens on his potential as a speed-driven depth option.
