Arizona Diamondbacks win series over Cubs amid sign-stealing and balk controversies

The Arizona Diamondbacks secured a crucial series win against the Chicago Cubs, highlighted by a dominant 2-0 shutout performance from pitcher Eduardo Rodríguez. Rodríguez recorded nine strikeouts over seven innings, helping Arizona maintain its position in the National League Wild Card race.

The series was marked by significant on-field tension and controversy. In one instance, Diamondbacks pitcher Merrill Kelly accused Cubs third base coach Quintin Berry of stealing signs by relaying information about pitch grips to Chicago hitters. While Diamondbacks management initially expressed outrage, manager Torey Lovullo later apologized after being informed by MLB that the practice was legal.

Further controversy arose during the final game when the Cubs protested a missed balk call. Cubs player Pete Crow-Armstrong and manager Craig Counsell argued that Rodríguez had disengaged from the pitching rubber during a delivery, which would have awarded a run to Chicago. The umpiring crew, led by Alfonso Márquez, reviewed the play but ruled that no balk had occurred, a decision that left the Cubs visibly frustrated.
