Overview

• Merrill Kelly, Arizona’s 9–6 ace with a 3.22 ERA, was sent to the Rangers for left-handers Kohl Drake and Mitch Bratt and right-hander David Hagaman.
• The trade capped an eight-day stretch in which the D-backs dealt five walk-year veterans—Eugenio Suárez, Josh Naylor, Randal Grichuk, Shelby Miller and Jordan Montgomery—for future assets.
• Arizona’s haul now totals eight pitching prospects, including Andrew Hoffman from Kansas City and three arms acquired earlier from Seattle.
• With those veterans moved, Zac Gallen is the only remaining player on an expiring contract while FanGraphs assigns the club a 1.6 percent chance of reaching the postseason.
• The pivot to a rebuild follows Corbin Burnes’s June elbow surgery and the loss of key relievers, which precipitated an eight-loss-of-nine slump under a franchise-record $187 million payroll.
