Travis Wood is going to the bullpen.

Joe Maddon said Wood, who picked up his first career save in Saturday’s 4-1 win over the Pittsburgh Pirates, will not make his next start and is heading to the bullpen. Wood is 2-2 with a 5.59 earned-run average and has struggled in May, allowing 15 earned runs in three starts.

That is before Saturday, when he threw a perfect ninth. Closer Hector Rondon had worked in three straight games, and though he warmed up, Wood got the chance to hold a three-run lead.

“He got a save,” Maddon said. “It was a beautiful thing, man.”

With Wood in the bullpen, there’s a hole in the rotation. Maddon said the Cubs would make an announcement Sunday about what they would do. He was then asked whether the announcement had something to do with Tsuyoshi Wada, whose rehab stint at Triple-A Iowa is expiring after he started the season on the disabled list with a mild left groin strain.

“We’ll announce everything tomorrow. That’s a good try,” Maddon said wryly. “I don’t cave that easily, man.”
