Jackson has signed a contract with the Chiba Lotte Marines of the Nippon Professional Baseball Organization, Jon Morosi of MLB Network reports. Jackson appeared in 28 games for the Brewers a season ago, finishing with a 4.45 ERA and 1.32 WHIP with a 47:18 K:BB over 30.1 frames. A return to Major League Baseball can't be ruled out at this point, though he'll likely need to show improvement overseas to earn a big-league contract.
Jackson elected free agency Friday. Jackson pitched in the big leagues in 2019 for the first time in four years, recording a 4.45 ERA in 30.1 innings. His 35.6 percent strikeout rate will likely generate some interest this offseason despite the fact that he just turned 32, though it came with a 13.6 percent walk rate.
Jackson tossed a scoreless inning of relief in Monday's victory over the Marlins. Jackson allowed two hits and two walks while covering parts of two frames, but he managed to keep the opponent off the scoreboard, and picked up his first hold of the season in the process. Monday's outing was a snap shot of Jackson's latest big-league stint, which dates back to Aug. 18: since that date he has allowed 10 hits and walked five batters over 10.1 frames, but he has allowed just four earned runs (3.48 ERA), thanks mainly to a stellar 16 strikeouts.
Jackson was recalled from Triple-A San Antonio prior to Sunday's game against the Nationals. The Brewers used 10 pitchers in Saturday's 14-inning win against the Nationals, so they needed reinforcements. Jackson should work in low-to-mid-leverage situations.
Jackson was optioned to Triple-A San Antonio on Saturday. He had been pitching fairly well, striking out 10 and allowing one run over his last 5.2 innings, but the Brewers wanted a fresh arm for the pen after Jackson was used in Friday's game. Aaron Wilkerson was recalled in a corresponding move.
