Hoyer, McLeod To Join Cubs; Byrnes Now Padres GM

Theo Epstein's first deal as the Cubs' president of baseball operations may be one of the most significant moves of his tenure in Chicago. The Cubs and Padres have confirmed that San Diego GM Jed Hoyer and assistant GM Jason McLeod will leave the Padres to accept positions with Epstein. 

Once the World Series ends, the Cubs will introduce Hoyer as their executive VP and general manager and McLeod as their senior VP of scouting and player development. The Cubs will send the Padres a player to be named later as compensation for the two executives.

Meanwhile, Josh Byrnes will be introduced as San Diego's executive vice president and general manager next Monday, according to the Padres. Byrnes, formerly the Padres' senior VP of baseball operations, worked under current Padres CEO Jeff Moorad in Arizona, so he already knows his boss well. Byrnes was Arizona's GM from 2005-10, leading the Diamondbacks to a division title in 2007 before losing his job last July. MLBTR's Transaction Tracker offers a look back at his moves as the club's GM.

The NL West has featured some noteworthy personnel changes in the past year and a half. A.J. Hinch, the former D'Backs manager who was fired along with Byrnes last July, is now San Diego's assistant GM, so Hinch and Byrnes, two former D'Backs, now run the Padres while a longtime Padres executive, Kevin Towers, runs the D'Backs.

Byrnes worked with Epstein and Hoyer in Boston before leaving for Arizona. Before Hoyer obtained the San Diego job, he worked for Epstein as Boston's assistant GM from 2006-09. McLeod was Boston's scouting director from 2005-09.
