Simmons' new deal with the Braves keeps him in Atlanta through the 2020 season, covering two free agent seasons. The 24-year old is the fourth Brave to sign a long-term extension in the last couple of weeks, joining Freddie Freeman (8 years, $135MM), Julio Teheran (6 years, $32.4MM with a team option for 2020), and Craig Kimbrel (4 years, $42MM with a team option for 2018). Adding in Jason Heyward's two-year, $13.3MM deal, the team has now spent $280.7MM on extensions for young players this month.

In 206 games over his first two major league seasons, Simmons has hit .256 with 20 HR and 78 RBI while being widely regarded as tht best defensive shortstop in baseball. He won his first Gold Glove award in 2013, finishing 14th in voting for the NL MVP award.

Simmons' deal may serve as a benchmark for Brewers' shortstop Jean Segura, who is also expected to discuss a contract extension this spring.
