The Brewers made their first big deal of the winter meetings on Tuesday morning, sending relief pitcher Tyler Thornburg to the Boston Red Sox in exchange for third baseman Travis Shaw, infielder Maurico Dubon and pitcher Josh Pennington.
Shaw, 26, is a left-handed bat who should compete for Milwaukee’s starting third base job. Last season with the Red Sox he batted .242 over 145 games, belting 16 home runs and knocking in 71 while seeing time at both third and first base.
Dubon, 22, split last season between High-A Salem and Double-A Portland, hitting .323 and stealing 30 bags over 124 games. He provides Milwaukee with even more versatility, showcasing a skillset to play both shortstop and second base.
Pennington, 21, spent 2016 at Class-A Lowell, going 5-3 with a 2.86 earned run average over 13 starts. A 29th round pick by Boston in 2014, Pennington posted an 0.82 ERA in seven GCL outings in 2015 and has held opposing hitters to a .205 average over two pro seasons.
Thornburg, 28, was a third round pick by Milwaukee in 2010. He made his MLB debut in 2012 and has spent the past five seasons with the Brewers, emerging as the team’s closer late last season.
