The Reds offered catcher Miguel Olivo a $100,000 retention bonus to accept an assignment to Triple-A Louisville.

Olivo has not decided whether he’ll take it or not. If he does, he still has an out on June 1. The Reds either had to offer him the bonus or put him on the 40-man roster.

The move essentially means that Devin Mesoraco made the team.

Mesoraco is hitting .361/.425/.611 with two home runs and 11 RBI in 36 at-bats. Olivo was hitting .167/.205/.333 with one home run and four RBI in 36 at-bats.

Olivo, the 34-year-old veteran, was brought in to compete with Mesoraco.

“I hate to see him go,” Reds manager Dusty Baker said. “A lot of guys on the team had come to know him. I knew him from before. Like I said sometimes, contractual things supersede. They preclude what you want to do.”
