Apparently Garcia can opt-out of the deal if not on the roster by March 25. So if he doesn't make the team he can become a free agent, if he makes the team he will make 1.25 million with another 1.25 in incentives to be had (2.5 million total if incentives are reached).
Beachy insurance policy. Can't hurt to have guys with experience like Floyd and Garcia lurking to help ease a little of the burden of expectation on Beachy and Wood.
As mentioned - Wood can start the season in the pen to help limit his innings. Then if/when Venters is ready, he can be sent to Gwinnett for a few weeks to get stretched out again. At that point, Floyd should be ready to go as well. Keeps Wren from having to start any of the younger guys' clocks early in the season. If Garcia struggles or someone in Gwinnett is on fire Freddy can always be released.
