Hannahan activated, back in Reds' lineup

CINCINNATI -- Corner infielder Jack Hannahan was activated from the 60-day disabled list and inserted into the starting lineup at first base for the Reds' series finale against the Nationals on Sunday at Great American Ball Park. Right-handed reliever Curtis Partch was optioned to Triple-A Louisville in the corresponding roster move.

Hannahan hadn't played all season, recovering from right shoulder surgery in October 2013 and enduring some setbacks along the way.

"It's exciting to get back out there and help these guys win," Hannahan said. "It's been frustrating with the setbacks and not being able to do my job, especially when they needed me to, filling in for the guys and giving guys a day off when they're banged up."

Hannahan played in 12 rehab games split between Class A Dayton and Triple-A Louisville. In four games as the designated hitter for Dayton, he went 4-for-12 with a double and an RBI. In eight games for Louisville -- five as the DH and three at first base -- Hannahan went 8-for-28 (.286) with two doubles and five RBIs.

"Whatever it is, whatever position or coming off the bench and hitting, or playing first," Hannahan said, "absolutely, I wouldn't be back in the lineup if I didn't feel like I could help this team out."

With Hannahan back, manager Bryan Price has a more experienced option at first base, enabling Todd Frazier, Jay Bruce and Brayan Pena to play their natural positions of third base, right field and catcher, respectively, more regularly.

"Now everyone sees Brayan Pena as a first baseman, for a guy that had maybe five total appearances at first base at the Major League level -- and none of them, I think, was a start -- coming into this year," Price said. "Certainly with Jay, and we had [Ryan Ludwick] over there taking ground balls. … Not that these guys will never play first base again. Brayan is going to continue to play first base, but maybe you don't have to experiment as much with Jay and the other guys."
