What happened: Ketel Marte is back in the trade rumor cycle, alongside a $400M contract projection for Tarik Skubal. Jeff Passan has said the Blue Jays could target Marte.

Why it matters: Diamondbacks GM Mike Hazen said the club needs "to look at some ways to shake the team up a little bit." Arizona's earlier Marte talks with Boston collapsed in February when the Diamondbacks asked for Marcelo Mayer. Skubal tops a list of the top 100 free agents.

What to watch: MLB's labor deal expires Dec. 1 with the salary cap unresolved, and an expected lockout could speed up free-agent deals.
