The biggest reason probably is the fact that he is a catcher.
Posey told reporters that he was able to drive home following the game and had no problems sleeping afterward.
The Giants have added catcher Tim Federowicz to the 25-man roster.
After San Francisco loaded the bases on an Eduardo Nunez infield single and a pair of one-out walks, Samardzija struck out for the second out before Hernandez hit a high, deep fly to left. "I'll take him every day". "When you're dealing with your head you have to use caution". It's different than a hip or a knee obviously. "I feel like it's the right move". "It's always a little scary and I never want to do that". They entered the game ranked third in the National League in innings pitched (43 2/3), and fourth in ERA (3.50) and opponents' batting average (.238).
But the Giants are also wizened enough to know that they can not know for sure.
Even with Tuesday's news that Posey would head to the seven-day disabled list, a shortened version of the disabled list specialized for concussions, it still seems the Giants have avoided the worst case scenario. That's part of what you come to expect (after a hit to the head).
Immediately after the game, Bochy said Posey appeared to be "fine". Groeschner led Posey off the field after a brief examination. "It's definitely nice to know that he's doing well so far". Posey said he will be patient and the Giants have specialists ready to help with the timeline.
Teammates who checked on Posey throughout the game said he assured them he felt OK.
The Giants hope their beloved catcher will not share the same fate their second baseman did past year.
"He did cardio and some lifting today and he's doing good", Bochy said. "Sure. But that's the luxury of having one of the elite closers in the game". For now, Brandon Crawford will take over the responsibility.
But with Posey out, the most likely outcome will be that everyone will slide up one place on the catcher's depth chart.
