The Diamondbacks signed Guillorme to a one-year contract Tuesday, Daniel Alvarez-Montes of ElExtraBase.com reports.
Per Alvarez-Montes, Guillorme is already with his new team at loanDepot Park in Miami, so it appears he will be active for Tuesday's game versus the Marlins. The Diamondbacks will need to make roster moves in order to add him to their 26-man and 40-man rosters. Guillorme, who was released by the Angels over the weekend, has a paltry .218/.285/.290 slash line in 138 plate appearances between Atlanta and Los Angeles. However, he offers a steady glove and gives Arizona an option at second base while Ketel Marte (ankle) is out.
