To make room on their forty-man roster for Jacobs, the Diamondbacks designated outfielder Cole Gillespie for assignment.
Jacobs signed with the Diamondbacks in January and spent the season with their Triple-A affiliate. Over 333 at-bats, he hit .279/.362/.486 with fifteen doubles and eighteen home runs.
Prior to his at-bat yesterday, Jacobs hadn’t appeared in a major league contest since the 2010 season. Over seven years in the majors the 31-year-old owns a career line of .253/.313/.474.
Jacobs was suspended for fifty games last season after testing positive for human growth hormone.
Gillespie, 28, has also spent the season at the Triple-A level, hitting .308/.390/.494 with thirty-five doubles and thirteen home runs over 441 at-bats.
