Because of my stay at the European Baseball Championship, I have missed quite some moves regarding several extensions of player development contracts.
Yesterday, September 11 was the deadline to extend player development contracts, so in the last couple of days there have been a lot of signings at the eleventh hour.
Five extensions have been signed.
The first one was between the Everett AquaSox (A Short Season, Northwest League) and the Seattle Mariners. 
The two parties extended the contract with the maximum number of years: four, through the 2020 season.
Both teams are cooperating since 1995.
Both teams exchanged the usual pleasantries.
“The Everett AquaSox are fortunate to have such a great relationship with Seattle Mariners personnel, on and off the field.” President of 7th Inning Stretch Pat Filippone said. “We look forward to continuing our relationship with the Mariners for the next four years and beyond.”
“The Mariners are excited to be able to extend our relationship with the Everett AquaSox, Mariners Director of Player Development Andy McKay said. “We are in a unique situation with having a Northwest affiliate so close to Seattle and the city of Everett and the AquaSox fan-base have always been great supporters of our minor leaguers and the entire Mariners organization. We are looking forward to continuing to bring a great brand of baseball to the area for years to come.”
Another PDC extension that was signed was between the Oakland A’s and the Beloit Snappers (Midwest League, A Full Season). The teams extended the contract with the minimum number of years: two, through the 2018 season.
The two teams have been together since 2013. Several players that played with the Snappers made it to the Bigs: Raul Alcantara, Liam Hendriks and Renat Nunez to name a few.
The New York Yankees and their A Full Season affiliate the Charleston RiverDogs have extended their player developement contract with four more years through the 2020 season. Apparently the Yankees are very happy with the cooperation, since a four year signing doesn’t happen that much. Both teams are together since 2005.
“We are excited to renew with the Charleston RiverDogs,” said Yankees General Manager Brian Cashman. “The franchise is a jewel of MiLB under Marv’s leadership and that of President and General Manger Dave Echols, and we couldn’t be happier to partner for another four years.”
Principal owner of the RiverDogs, Marv Goldklang stated: “We’re thrilled to continue our relationship with the Yankees, the most successful and recognizable organization in professional sports. This has been a mutually beneficial partnership since the outset, providing a first- class facility and playing surface to help the Yankees develop premium on-field talent while we entertain fans with our award-winning off-field experience.”
Another PDC extension was signed between the Angels and the Orem Owlz. Since the Owlz 
arrived in Utah in 2001 both teams are linked together.
The teams extended their cooperation with two more years.
Big-leaguers like Kole Calhoun, Mark Trumbo, C.J. Cron, and a lot of others have started their professional career at the Home of the Owlz.
The final PDC extension was the one between the Visalia Rawhide and the Arizona Diamondbacks.
After ten years in Visalia, the D-Backs still don’t have enough from the gateway to several National Parks in California. The two teams extended the contract with two more years. Only the Minnesota Twins had a longer tenure in Visalia (1977-1992).
“We’re fortunate to have great working relationships with our partners — the City of Visalia and the Arizona Diamondbacks,” said Rawhide General Manager Jennifer Pendergraft. “We’re proud to have a facility with a charming personality for affordable family entertainment in the greater Visalia community, and we’re grateful for the Diamondbacks’ continued patience as we work with the city on the playing surface & other areas that fall short of the MLB standards. We continue to work toward creating a proper home for Professional Baseball and the growing number of events at this beautiful community gathering place.”
