• Don Welke, who has spent eight seasons with the Rangers, is leaving the organization to join A.J. Preller with the Padres. Preller was hired by the Padres as their general manager earlier this month, and there are significant restrictions as to who he can hire from the Rangers.
But Texas did give him permission to hire Welke, who was one of Preller's early mentors when they were with the Dodgers. Welke had been working for the Rangers under the title of special assistant to the GM, but he was involved in all areas of scouting both amateur and professional.
Welke was among the scouts sent to Japan to watch Yu Darvish pitch. He also was instrumental in the acquisition of Josh Hamilton, Cliff Lee and Adrian Beltre, and the amateur signings of Jurickson Profar, Martin Perez, Jorge Alfaro and Luis Sardinas.
• Outfielder Engel Beltre, who has been out all season while recovering from a broken bone in his left leg, has been recalled from his medical rehab assignment because of continued soreness. He will be examined further by Dr. Keith Meister later this week.
• Double-A Frisco outfielder Nomar Mazara was named the Texas League Player of the Week after going 8-for-22 with two home runs and six RBIs.
• Outfielder Jamie Jarmon, who was the Rangers' second-round pick in the 2012 First-Year Player Draft, has left the organization to play college football at the University of Delaware.
• Marlins Park is the 48th ballpark the Rangers have played in since 1972. They have now played in all the current parks.
