Thompson (7-4) was the losing pitcher in Saturday's game against the Dodgers, allowing two runs on three hits while striking out one over one inning.
Thompson entered with one out and a runner on and got the Diamondbacks out of the eighth inning unscathed, but trouble followed him in the ninth. He was removed after a pair of singles and a sacrifice bunt, then watched Justin Martinez let his two runners score. Thompson has largely been a dependable bullpen arm but is showing cracks this month. The submarining right-hander has a 6.17 ERA and a .327 batting-average against over 11.2 innings in August.
