Smart teams would be willing to give up good assets for Chas and Diaz (and obviously Tucker).
I know I’m a broken record, but Chas has been 30% better than league average offensively as a good defensive CF, with years of team control. He’s at 1.7 fWAR in 53 games, meaning he’s playing at the level of a 5-win player (all star).
Diaz is a catcher who hits the ball really hard. It isn’t difficult to see him as one of the 4-5 best offensive catchers in MLB. He’s also the best defensive catcher on the club. He’s a rookie.
Both of those guys should get you really big haul. The Astros shouldn’t move them. Rather, they should move the manager who doesn’t understand their value.
(I know you’re not saying we should move anyone necessarily; just saying that we have some valuable trade chips if we wanted to, like these guys, Tucker, Pena, etc. Obviously the best idea is to keep those guys for now.)
