Guillorme started at second base and went 0-for-2 with two walks, a run scored and a stolen base in Saturday's 4-1 win over Boston.
Guillorme, who was signed last Tuesday, made a third consecutive start -- all against right-handers -- and appears to have moved into a platoon at second base with Kevin Newman for as long as it takes Ketel Marte (ankle) to return. Marte is not yet asymptomatic, manager Torey Lovullo told Arizona Sports on Friday, so there could be plenty of opportunities for Guillorme in the short term. The utility infielder is 2-for-10 with four walks, one RBI, two steals and two runs scored in his first three games with the Diamondbacks.
