Jack Flaherty pitched six innings of shutout ball against the Chicago Cubs, helping Detroit Tigers win the game 4-0 today at packed Comerica Park.

The Cubs whiffed on eight of 16 swings at the knuckle-curve. Five of his nine strikeouts were with that pitch. Conversely, with the hitters focused on the spin, Flaherty stole 17 called strikes with a four-seam fastball that he was locating on the edges and especially at the bottom of the strike zone.

Chicago Cubs manager Craig Counsell, center, argues with home plate umpire Derek Thomas (53) after Nico Hoerner, right, was ejected for arguing after being called out on strikes during the fifth inning of a baseball game Sunday, June 8, 2025, in Detroit. Counsell was also ejected from the game.
