Perdomo started at shortstop and went 2-for-3 in Wednesday's 1-0 loss to San Francisco.
Perdomo, who was called up Sunday, made his second start in three games while serving as a pinch hitter in the other. He's hit in all three contests, going 4-for-6 with a double and a walk. He and Josh Rojas are sharing shortstop until the end of the season with Nick Ahmed (shoulder) done for the year. Looking ahead to 2022, the 31-year-old Ahmed still has two years left on his deal and the versatile Rojas has earned an everyday spot somewhere. It looks like Perdomo will build off the success he achieved in August at Double-A Amarillo while beginning 2022 at Triple-A Reno.
