Machado is the shiny object but I have seen
Raisel Iglesias start to bubble up as a possible reliever to hit the market. He seems like a nice fit for the Indians and would create a pretty strong 1-2 if Miller ever gets back.
Effective at all bullpen spots and the ability to pitch multiple innings / under team control for an additional year. He's one of the few guys rumored to be on the market that is still relatively young and has sustained success over 100+ innings. No clue what it would cost though.
I'll also get on my stump here and say the Indians should swallow pitching assets for power positional players. The Indians have infield versatility to lean on here.....where if they acquire a plus player who can hold down 3rd, we could kick Jose to 2nd and bump Kips blackhole spot out of the lineup. It's too bad Machado is a stuck up prick, as he would be the ideal acquisition to do the above, assuming we could protect the obvious farm guys. The organization has an incredible track record at identifying and developing pitching talent. We can find more pitchers (and will). I'm not advocating for the club to recklessly overpay but I do think we need to consider cashing in an arm or two for someone who can displace Kip. I don't think that's MM, given the chatter out of his camp but there do seem to be some other options out there that are cheaper.
