It's no secret to Astros fans that the ascension of Hunter Brown is one of the primary reasons the team was able to rebound from a disastrous start to the season.

Astros manager Joe Espada has seen enough from Brown to start throwing around the word “ace” when talking about him.

And it appears the biggest key to Brown's turnaround was mixing in a two-seam fastball to keep right-handed hitters honest. Brown needed a pitch that could command the inside of the plate, which allows his other pitches to be more effective.

We learned just recently, from Chandler Rome of The Athletic, that Alex Bregman was the one that suggested the addition of the two-seam fastball to Brown's arsenal.

Come to find out, Bregman often shares advice on how to attack hitters. Or he'll ask pitchers why they chose a certain pitch in a specific situation.

This just goes to show that veteran leadership can make a big difference. Especially on a team with so many young pitchers and catchers. Bregman was able to help Brown when no pitching coach could.

For Brown, this small tweak could be the catalyst that changes the course of his career. And the Astros season for that matter.

However, some will say the difference in Brown is more about confidence than anything else. But confidence only builds after repeated success. Nobody knows where Brown would be without the two-seam fastball.

Looking ahead

If the Astros do make the playoffs, where will Espada slot Brown in the playoff rotation? Framber Valdez has the playoff experience, so he'll probably be penciled in as the number one starter.

Justin Verlander (neck) still isn't facing live batters, so it's hard to count on him. Ronel Blanco has been an All-Star level pitcher this season, but he doesn't have any experience pitching playoff games for the Astros.

So it wouldn't be surprising at all if Brown is the team's number two starter. In all likelihood, whoever is pitching the best at the end of the season may get the nod. But it's fun to discuss in the meantime.

Finally, how does Hunter Brown's arrival impact the Astros' plans at the trade deadline? And how could that affect Justin Verlander's future with the club?
