Wood earns first save in move to bullpen

CHICAGO -- Travis Wood's appearance in the ninth inning and his first career save on Saturday were no fluke.

The starting pitcher has moved to the bullpen, Cubs manager Joe Maddon announced after his team beat the Pirates 4-1 on Saturday. Maddon said the Cubs will reveal their rotation plans on Sunday.

"He's going to be in the bullpen, and we'll make an announcement regarding what we're going to do tomorrow at some point," Maddon said.

One possibility is left-hander Tsuyoshi Wada could join the rotation. Wada, whose rehab assignment is expiring, has been on the disabled list since March 27 for a mild left groin strain. Maddon said the Cubs were discussing what to do with the starter.

Wada is 1-3 with a 2.86 ERA in six starts at Triple-A Iowa. He allowed a run and struck out six in seven innings in his last start Thursday against Nashville. Last season, he went 4-4 with a 3.25 ERA in 13 starts with the Cubs.

Wood pitched a 1-2-3 ninth inning with two flyouts and a popout in his fifth career relief appearance and first since Sept. 17, 2011, against Milwaukee. He has a 0.00 ERA in six relief innings. Four of his bullpen appearances were with the Reds in 2011.

Wood, an All-Star in 2013, is 2-2 with a 5.59 ERA this season. He allowed five runs in 4 1/3 innings against the Mets on Thursday in his last start.
