Red Sox president of baseball operations Dave Dombrowski was already looking to shore up his beleaguered bullpen when closer Craig Kimbrel was hurt shagging flyballs.
Suddenly, Dombrowski had another big hole to fill.
And he did.
The Red Sox acquired Arizona closer Brad Ziegler early Saturday, hours after learning Kimbrel would likely be sidelined for three-to-six weeks with an injured left knee. He was hurt during BP before Friday's win over Tampa Bay.
"I took a step for a groundball, heard a pop and didn't really think it was anything serious," Kimbrel said in the dugout about 75 minutes before Boston's game against Tampa Bay.
