The Oakland Athletics extended their player-development contract with the Beloit Snappers through the 2018 season, the clubs announced Friday. They have been affiliated since the 2013 season.

“We are very pleased to extend our affiliation with the Athletics for another two years,” Snappers president Dennis Conerton said in a press release. “We have enjoyed working with their staff over the past four years and look forward to continuing this working relationship. It has been exciting for our fans to already have three of our former Snappers players from the previous four seasons advance to the major-league level for the A’s and we anticipate seeing many more do so in the future.”

Those three players are RHP Raul Alcantara, RHP Ryan Dull and catcher Bruce Maxwell. All three played for Beloit in 2013, as did 3B/OF Renato Nunez, a Triple-A player who is on Oakland’s 40-man roster.
