The Arizona Diamondbacks have acquired reliever Heath Bell and infielder Cliff Pennington in a pair of trades that sent outfielder Chris Young to the Oakland Athletics.
Arizona obtained Pennington and minor league infielder Yordy Cabrera from Oakland for Young and cash, then sent Cabrera to the Miami Marlins for Bell and cash.
Earlier in the day, Arizona exercised a $6.5 million option on closer J.J. Putz.
Arizona general manager Kevin Towers says Bell provides a right-handed power arm to help set up Putz and Pennington gives the team experience at shortstop and second base.
Young, Arizona's center fielder for six seasons, was the odd man out in a crowded outfield with the team expecting young Adam Eaton to play center and be its leadoff hitter.
