The San Francisco Giants were dealt a scare Thursday, as catcher Buster Posey suffered an ankle injury during a swing and "limped badly" as he went to the clubhouse against the Colorado Rockies, per John Shea of the San Francisco Chronicle.
Shea announced shortly after that Posey was dealing with a sore ankle and is considered day-to-day.
The 30-year-old is arguably the most important player on the Giants roster, and that has been the case for several seasons.
A four-time All-Star, Posey is hitting .348 with eight home runs during the 2017 campaign.
He entered the season having appeared in at least 146 games in five straight years, which is no small feat for a player who primarily contributes at catcher.
This season has been a bit of a struggle for Posey injury-wise, though, as he was previously placed on the seven-day concussion disabled list on April 11 after getting hit in the head by a pitch from Taijuan Walker of the Arizona Diamondbacks.
Few backstops in the league are as consistently productive offensively as Posey, which makes him nearly impossible to replace.
As a three-time World Series champion, Posey has a wealth of experience and can be trusted to come through in nearly any situation.
The Giants have a solid backup in Nick Hundley, who has some pop as evidenced by his 10 home runs in both 2015 and 2016, but the drop-off is significant. Posey's potential absence also impacts San Francisco's depth behind the plate and will likely require it to call up Tim Federowicz from the minors.
Regardless of how the Giants divvy up the playing time at catcher in the event of Posey's absence, there will be a major hole in the lineup.
