Houston Astros shortstop Carlos Correa revealed after his team’s Game 7 World Series win over the Los Angeles Dodgers that he had been playing with an injured thumb since the American League Championship Series, according to Ken Rosenthal of FOX Sports and The Athletic. Correa said that he originally hurt his thumb during the Astros’ walk-off celebration in Game 2 of the ALCS against the New York Yankees.

Since then, he had received a series of injections in the thumb, which resulted in some needle marks that were visible to the aforementioned Rosenthal.

That didn’t seem to slow the 23-year-old down, though, as he slashed .276/.300/.517 with two home runs and five RBIs over 30 plate appearances during the “Fall Classic.” Throughout the 2017 postseason overall, Correa registered a slash line of .288/.325/.562 while connecting with five long balls, five doubles and driving in 14 runs.
