On Opening Day when the Atlanta Braves faced the Phillies, Luke Jackson surrendered 4 earned runs in one inning.
His ERA after that appearance was 36.00.
Since then, Jackson has pitched 10.1 innings and allowed no earned runs.
Yes, you read that correctly — no earned runs.
Jackson, who was the butt of most of our bullpen jokes in 2018 (Sam Freeman, notwithstanding), has become the Atlanta Braves most reliable reliever early in the 2019 season.
MLB Trade Rumors recently listed Jackson as one of the 10 breakout relievers during the early portion of the season.
