Astros rookie shortstop Carlos Correa continues to announce his presence with authority. The latest? This mammoth blast in Game 4 of the Royals-Astros ALDS:

Correa is 21 years and 20 days old, so this means he's the youngest shortstop to ever hit a postseason home run (skip down to see that he homered again and how that ranks historically). The top five:

1. Correa
2. Chris Speier, 21 years and 100 days, Oct. 10, 1971
3. Alex Rodriguez, 22 years and 66 days, Oct. 1, 1997
4. Derek Jeter, 22 years and 105 days, Oct. 9, 1996
5. Troy Tulowitzki, 22 years and 359 days, Oct. 4, 2007

If we drop the shortstop requirement, Correa checks in as the 11th youngest ever, behind Andruw Jones (twice), Bryce Harper, Manny Machado, Miguel Cabrera (four times) and Mickey Mantle (twice). That's some fine company.

Further, it's not just Correa among rookies making noise this postseason. Check this out:

That's Correa along with Michael Conforto, Randal Grichuk, Jorge Soler, Stephen Piscotty, Tommy Pham and Kyle Schwarber. Given the strong rookie class in this postseason, the best bet is that record comes crashing down sooner rather than later.

Oh, and Correa doubled home George Springer to give the Astros a 3-2 lead in the fifth inning Monday. UPDATE: He homered again in the eighth, meaning he was 4 for 4 with two homers, a double and four RBI in Game 4.

Only Jones (19 years and 180 days) was younger among players with a multi-homer game in the playoffs.

Simply put, Carlos Correa is already a star and now the entire nation is witnessing it.

Carlos Correa became the youngest shortstop to ever homer in the playoffs.
