Jackson got the save in Sunday's 10-3 win against the Brewers, allowing two runs on four hits with three strikeouts in three innings.
Jackson entered in the seventh inning with Los Angeles ahead 10-1 and went the rest of the way to earn the save by virtue of pitching the final three innings of the victory. The 25-year-old rookie saw action in only three big-league games this season, finishing with an 0-1 record, a 2.31 ERA, a 1.37 WHIP and a 10:6 K:BB in 11.2 innings.
