AP Source: Padres get Pomeranz in exchange for Alonso

SAN DIEGO (AP) A person with knowledge of the deal says the San Diego Padres have traded first baseman Yonder Alonso and reliever Marc Rzepczynski to the Oakland A's for left-hander Drew Pomeranz and minor league pitcher Jose Torres, plus either a player to be named or cash.

The person spoke with The Associated Press on Wednesday on condition of anonymity because the trade hadn't been announced.

Pomeranz can either start or come out of the bullpen. He had surgery on his pitching shoulder in October and is expected to be ready by spring training. He was 5-6 with a 3.66 ERA in 53 appearances with nine starts spanning 86 innings for the A's in 2015.

Alonso was limited to 103 games in 2015 due to injuries.
