If you’re going to rebuild with 22 year old players in the starting lineup, situations like Marte are probably going to happen. It’s an unfortunate part of the rebuilding process. I wouldn’t give up on him but I don’t think he currently belongs in the majors.
He’s striking out more, 31%, and walking less, under 3%, this year. He’s never been that type of hitter. He definitely needs a re-set. His defense has always been overrated because he moves well out there, but he was error prone in the minors. His professionalism should improve with maturity.
I’d be careful not to give this guy away, I think it would be a mistake. But I’d start him off at AAA next season. I wouldn’t risk another season of this type of performance if Reds are trying to win in 2025.
