Astros Boast Elite Infield For 2023
The Astros 2023 infield may be the best in all of baseball.
There are stars at every position, three of which have at least one World Series title under their belts.
They also have two former MVPs and a rising star who busted out in full force during the postseason, while also proving to be a solid replacement for the now departed Carlos Correa.
The Astros won 106 games during the regular season.
Even after winning the World Series, Houston remains hungry for more, as evidenced by the signing of Abreu.
Their lineup is already deeper than it was in 2022, but the infield is loaded with superstars at every position.
