Heading into the trade deadline season, Seattle Mariners’ executive Jerry Dipoto has real pressure on him, according to Buster Olney of ESPN. There is a clear need for a thumper, whether it’s Ryan O’Hearn orJosh Naylor– or someone of that ilk. As with the Orioles a year ago, the Mariners’ farm system is loaded, and Dipoto can present a buffet table of options to rival executives looking for a match. Dipoto is in his 10th year with the Mariners, and the team has just one playoff berth in the first nine.
