Dunning was traded from the White Sox to the Rangers on Monday in exchange for Lance Lynn, Jeff Passan of ESPN.com reports.
The Rangers elected to trade away their ace from a season ago, but they'll receive one of Chicago's top prospects in return. The right-hander has appeared in just seven major-league games (all starts), posting a 3.97 ERA, 1.12 WHIP and a 35:13 K:BB through 34 innings. Dunning should slot right in as a top-three starter for his new team, as the Rangers' rotation is very unsettled at the moment.
