Overview

• The Arizona Diamondbacks sent Josh Naylor to the Seattle Mariners for prospects Brandyn Garcia and Ashton Izzi, officially launching their July 31 selloff.
• Analysts view the Naylor trade as the first market benchmark of deadline week, prompting contenders to recalibrate their valuation of expiring-contract players.
• Arizona is preparing additional veterans—third baseman Eugenio Suárez and starters Zac Gallen and Merrill Kelly—for potential trades to bolster its farm system.
• After missing out on Naylor, the Red Sox have turned their attention to Orioles first baseman Ryan O’Hearn as their primary left-handed power option.
• Injuries to Tanner Houck, Kutter Crawford and Hunter Dobbins have intensified Boston’s need to add at least one starter and one high-leverage reliever before the deadline.
