I think the expectation is two bats and two relievers. With the smoke around Bellinger and Hoskins, combined with the fact that it's pretty tough to see a lot of alternatives for either of them them (Giants for Hoskins...and who the heck knows for Bellinger), I'm starting to chalk them up as more or less inevitable.
The relievers it would be foolhardy to anchor onto one or two. Robert Stephenson and Matt Moore have each gotten mentions, and they're the approximate level of cost and impact I expect so they're the placeholders in my head right now.
Chris Morel and the trade market are where I think there's some opportunity for wiggle room. My expectation at this point is they're just going to try and make Morel at 3B work. If it doesn't, Madrigal can step in and be adequate until one of the youths or the trade deadline can address the position more satisfactorily. If he doesn't get run at 3B, he would seem to be a trade chip. We know from all the local writers Jed's been working the phones with other teams pretty hard. I expect a couple of trades, even if they're minor ones around the bullpen or bench.
