Nothing is done yet, but from Dan Connolly at the Baltimore Sun:
The Orioles have rekindled their trade talks with the Pittsburgh Pirates to acquire outfielder Travis Snider and are discussing a deal that would send one or two minor leaguers to Pittsburgh, according to industry sources.
[…]
Neither minor leaguer being discussed is thought to be on the Orioles’ 40-man roster, but at least one — and possibly both — is a pitcher.
Connolly is tweeting updates (including a name: Steven Brault), so you should follow him for the latest news. I don’t really want to spend a ton of time speculating beyond noting that while Snider was a very useful player down the stretch last year, the Pirates have some redundancy in the left-handed corner outfielder department with Gregory Polanco and Andrew Lambo. If there is a trade, I’d rather hold off on judgment until we’re sure who’s in it.
