Getting back to winning baseball
2017-18: RHP Anibal Sanchez
One of the most impactful free agent signings by Atlanta since 2010 was Sanchez, whom the Braves signed to a minor league deal prior to the 2018 season. In what was his lone season with the Braves, Sanchez posted a 7-6 record with a 2.83 ERA and 135:42 K:BB ratio across 136.2 IP.
2018-19: 3B Josh Donaldson
The 2018-19 offseason saw the Braves bring back former catcher Brian McCann, along with others moves that included re-signing Nick Markakis and signing pitcher Josh Tomlin. However, the biggest move was easily signing Donaldson, who slashed .259/.379/.521 with 37 HR, 94 RBI, and four SB in his lone season with Atlanta.
2019-20: OF Marcell Ozuna
One of the most impactful offseasons for the Atlanta Braves recently came in 2019-20, which saw the club sign Ozuna, along with others such as catcher Travis d'Arnaud and pitchers Will Smith, Chris Martin, and Darren O'Day. The biggest signing of that group was likely Ozuna, as he went on to be one of baseball's top hitters during the shortened 2020 campaign by slashing .338/.431/.636 across 60 games, as well as leading the NL with 18 HR and 56 RBI.
2020-21: RHP Charlie Morton
Atlanta's 2020-21 offseason included a few notable signings such as Marcell Ozuna, Drew Smyly, Josh Tomlin, and Ehire Adrianza, but easily the biggest was Morton, who became a key piece of the Braves 2021 World Series winning team. That season, Morton led the MLB with 33 starts made, and owned a 14-6 record with a 3.34 ERA and 216:58 K:BB ratio across 185.2 IP.
