I wonder if we will see Contreras come up for a few weeks once we get to about June/July to catch some games in order to keep Montero fresh? There's a stretch of 20 straight games from end of June into the first weekish of July, that wouldn't be a bad time to bring him to start maybe 5 of those games. I'm sure Contreras will be up by September, but one of the problems is one of roster spots. All the players at the bottom of the roster need to pass through waivers to be sent down(Szczur, Ramirez, Richard, etc) so you risk losing that guy for good if you do it. There are worse fates than letting Szczur go, and injuries/performance might open a more obvious spot by summer, but at the moment I'm not comfortable being certain that tradeoff will work itself out.
