The Reds on Friday added some depth to their bullpen and behind the plate by signing two free agents. Lefty Manny Parra was signed to a one-year contract worth a reported $1 million, with a chance to earn an additional $400,000 in appearance bonuses. Earlier in the day, the club signed catcher Miguel Olivo to a Minor League contract with an invite to big league Spring Training as a non-roster player.
