My hope is that they decided that Fredi was OK for 2015 due in part to it being a reload/rebuild year. But that they will not renew his contract when it runs out after this coming season. So instead of firing him they just let him finish his contract this season and find a new manager for 2016.
If there serious about being a contender by 2017 then Fredi surely won't being managing the team once the new ballpark opens.
