The run occurred in the second inning, when Mac Williamson led off with a double and scored on Juniel Querecuto's sacrifice fly with the bases loaded. Anderson rebounded to strike out Trevor Brown and Joan Gregorio to end the frame.
Anderson is 3-5 with a 5.85 ERA in 11 Major League starts.
Also, righty Jon Gray (0-0, 4.38 ERA in three Major League starts this season), who suffered a navicular stress fracture in his left foot April 13, will start Monday for Albuquerque at Sacramento. It's the second rehab start for Gray, who struck out five and gave up four hits in four innings for Class A Lancaster against Lake Elsinore on Wednesday.
