Cubs’ Hidden Ace: Ryan Zeferjahn | MLB News

The Cubs just pulled off a sneaky genius move at the trade deadline: Ryan Zeferjahn, a 28-year-old reliever with elite heat and a nasty sweeper, is quietly turning into their most dangerous weapon. Throwing 97 mph and striking out a third of batters, he’s already ranking among the league’s best at making hitters swing early or late — and his fastball? It’s allowed only four hits all year. While his walk rate was a concern, he’s now crushing it in his latest stint, walking just two in 11 outings while dominating. With free agency not until 2031 and a new mound position helping him refine his stuff, Zeferjahn might be the unsung hero who lights up October.
