Here's what I am going to say about Spring Training 2027, in its most general terms possible:
Now of course this is just my opinion, but...
I believe ST 2027 will be an OPEN COMPETITION for rotation spots.
Nobody is guaranteed anything.
Maybe Valdez simply because of his contract and "Veteran", but that could also be possibly "provisional" in the sense that he might lose his spot due to an unforeseen injury or... a trade? Highly improbable he will be moved in a trade to any team. But... just sayin' (in order to "cover all bases"). So I will just say (IMO) he is 95% in our 2027 rotation.
But all other competitors, yes, including Reese Olson, Jackson Jobe, River Ryan, Keider Montero, Troy Melton, Andrew Sears, Jackson Wolf, Drew Anderson & Ty Madden and anyone else who wants to toss their hat into this ring... Will have to EARN a 2027 rotation spot.
Again... just my opinion. But Olson is guaranteed NOTHING. Neither are any of the other candidates.
The only other thing I have to say is...:
May the best 5 win.
