The Diamondbacks have signed 31-year old lefty swinging 1B Mike Jacobs to a minor league deal. Jacobs played in 117 games in AAA-ball for the Rockies last year and he was 128 of 429 (.298 avg, .910 OPS) with 70 runs scored, 23 homers, 97 RBIs and 3 stolen bases. He last played in the majors back in 2010 with the Mets. Jacobs has played in 556 games in his first six years in the majors and he is 489 of 1,930 (.253 avg, .787 OPS) with 244 runs scored, 100 homers, 310 RBIs and 5 stolen bases. The D-Backs will likely stash Jacobs in AAA and give him a call to the show if something happens to Paul Goldschmidt or Lyle Overbay.
