With Sean Newcomb potentially headed to the rotation, outside of Will Smith, who will likely assume the closer role sooner rather than later, the Braves have a shortage of proven lefties.
Grant Dayton has shown promise and could be primed for a bigger role, and perhaps A.J. Minter can turn things around after a forgetful 2019. Phillip Pfeifer or Tucker Davidson could also be surprise contributors in 2020. But with no clear-cut proven options, and given the general volatility surrounding relief pitching, it always makes sense to go with the law of large numbers.
For that reason, Alex Anthopoulos has added another southpaw to the mix on a minor league deal in Chris Rusin. Rusin, 33, found himself in the minor leagues last season, so ultimately he could end up serving as organizational depth. But he did have a nice run with the Rockies from 2016-17, appearing in 89 games, including seven starts, posting a 3.19 ERA, and that was with Coors Field as his home park. While he may end up spending the majority of his season in Gwinnett, if Newcomb makes the rotation, it could be an open competition for these guys to battle it out for the final bullpen spot. Rusin presents some upside and does not take up a 40-Man Roster spot.
