Left-hander Dontrelle Willis, who was in camp with the Brewers on a minor league deal, has informed the Brewers that he will retire, tweets MLB.com’s Adam McCalvy. A neck injury has slowed him this spring, and the former Rookie of the Year had yet to get into a game.

Willis beat out Scott Podsednik and Brandon Webb for the 2003 NL Rookie of the Year Award at the age of 21 and helped the Marlins to their World Series victory that season. In his first four years in the league, the “D-Train” turned in a strong 3.44 ERA with 6.7 K/9 against 2.8 BB/9. Though he reached the 200-inning mark for a third straight season in 2007, however, Willis’ ERA spiked to 5.17, and he was traded to the Tigers alongside Miguel Cabrera that winter. Willis’ career never got back on track after that point, however, as the southpaw worked just 199 innings over the 2008-11 seasons, pitching to a 6.15 ERA with more walks than strikeouts.

Since the 2011 season — the last that he pitched in the Majors, Willis has pitched for minor league affiliates of the Giants (twice), Reds, Orioles and Angels in addition to a pair of stints in the independent leagues. He’ll retire with a 4.17 ERA in 1221 2/3 Major League innings and over $40MM worth of career earnings, per Baseball-Reference.com. We at MLBTR wish Willis well in his post-playing days.
