Ozuna plays 2B/SS/3B/LF, he's a veteran, he has hit in the past, he's under contract cheap enough as a backup.
Ramirez plays 2B/SS/CF, he's unproven, he hasn't hit much yet, he's under a long term deal.
Both have their places as utility guys.
Owens wouldn't be much better than either of them.
Ramirez will go to AAA when Richar's healthy -- most likely.
