O'Brien retired all three batters he faced with two strikeouts to earn the save in Friday's 2-1 win against Atlanta.
O'Brien needed just 12 pitches to retire the side in order and convert his 10th consecutive save opportunity. That brings the right-hander up to 23 saves on the season, moving him back into a three-way tie with Mason Miller and Jhoan Duran for the National League lead. While he has not blown a save since mid-May, O'Brien surrendered six runs with a 7:7 K:BB across 10 appearances in June. He finished the month with three straight scoreless outings and has followed up with three more clean appearances to begin July.
