Ransom had a "breakout" season in 2012, as the 37 year-old hit .220/.312/.411 last season for the Arizona Diamondbacks and the Milwaukee Brewers. Ransom only had amassed 383 major-league plate appearances prior to 2012.
Ransom started three games for the Padres at third base and made appearances in two others. The infielder went hitless in his first 11 plate appearances, striking out five times.
In a corresponding move, the Padres are purchasing the contract of Weber from Triple-A. Weber, 28, spent most of his career in the Detroit Tigers farm system. He made his major league debut for Detroit last season, making two appearances out of the bullpen for the Tigers in 2012.
The Padres claimed Weber off waivers last season. Weber made one start in 2013 for the Padres Triple-A team, striking out five while allowing one run in five innings of work.
