Shields has been traded to the White Sox in a deal that sends Erik Johnson and Fernando Tatis Jr. to the Padres, CSN Chicago's Dan Hayes reports.

EDGE Analysis

The 34-year-old righty profiles as an innings eater at this point in his career, as he posted a 3.91 ERA last year and he currently boasts a 4.28 ERA that is supported by a 57:27 K:BB in 67.1 innings through 11 starts in 2016. The Padres were willing to eat a significant chunk of the remaining money on Shields' contract in order to get too unexciting young players back, so that speaks to Shields' lack of value on the open market. It's a downgrade in home ballparks for Shields, but more importantly, the move back to the American League should work against him, as he'll face more quality lineups without getting two or three chances against the opposing pitcher each night. The White Sox also have a notably worse defense than San Diego according to Fangraphs WAR, so there's really no way to paint this move in a favorable light, other than the fact that he could be in line for a few more wins on a more competitive club.
