MILWAUKEE -- The Brewers on Wednesday sent Minor League right-handers Kevin Shackelford and Barrett Astin to the Reds, completing the Aug. 31 trade that sent reliever Jonathan Broxton to Milwaukee.
Shackelford, 25, began the year on the Brewers' 40-man roster but was outrighted in July amid a mixed season. A former catcher who converted to pitching at Marshall University, he posted a 0.87 ERA in 12 games at Class A Brevard County before making 40 appearances at Double-A Huntsville with a 4.86 ERA.
Astin, 22, was Milwaukee's third-round Draft pick in 2013 out of the University of Arkansas. He was 8-7 with a 4.96 ERA and four saves for Class A Wisconsin, finishing second on the team with 121 2/3 innings.
The Reds were also motivated by finances in the trade. The Brewers will owe Broxton $9 million next season, and his contract also includes a mutual option for 2016 at another $9 million, with a buyout that increased from $1 million to $2 million because he was traded. Broxton, a former closer for the Dodgers and Royals, would be the leading contender to fill that role in Milwaukee next season should Francisco Rodriguez depart via free agency.
Entering Wednesday, Broxton had made four scoreless appearances for the Brewers.
