The Braves are interested in working out pre-arbitration extensions with Andrelton Simmons and Julio Teheran, according to the New York Post.
The team worked on a similar deal with Jason Heyward, and was able to hand out a long-term extension with Freddie Freeman. The Braves are a file and trial team, but clearly would prefer to avoid the arbitration process when possible.
Both players are under team control for a number or years. Teheran is not expected to be a free-agent until after the 2018 season. There's some uncertainty about Simmons' control, but he may be on the same path, according to Cot's Baseball Contracts.
