Giants name Caleb Kilian closer, shifting bullpens roles before Cub series

The San Francisco Giants named Caleb Kilian as their closer prior to their series against the Chicago Cubs on June 13. This decision marks a departure from their previous committee approach to save opportunities. Manager Tony Vitello noted the need for more organization within the bullpen, which has struggled with a 5.35 ERA since late April. Ryan Walker, formerly the closer, has returned from the minors and is shifting roles, expected to handle high-leverage situations prior to the ninth inning. The Giants look to stabilize their bullpen as they enter a critical segment of the season.
