It was only a couple days ago that Seattle Mariners president of baseball operations Jerry Dipoto was openly talking about wanting to be "aggressive" on the bullpen market, and the big move that this would entail may yet happen before the trade deadline passes on Thursday.
In the meantime, the Mariners have pulled off a generally unspectacular, yet highly intriguing trade for Pittsburgh Pirates left-hander Caleb Ferguson.
The deal was first reported by Ken Rosenthal of The Athletic, with Adam Jude of The Seattle Times subsequently reporting that right-handed prospect Jeter Martinez is the return for Pittsburgh.
