On the 20th, no enemy planes attacked TF 58. Instead, the Japanese began their retirement toward Japan. American carrier search planes found the enemy late in the day, and TF 58 launched air strikes from extreme range. After darkness fell that evening, "Yarnall"'s searchlights helped to guide the returning airmen to their carriers. The following day, the destroyer returned to the coast of Saipan to resume call fire missions supporting the troops fighting ashore. She continued her labors in the Marianas until 8 July, when the warship left in the screen of a convoy bound for the Marshalls. After arriving at Eniwetok on the 12th, she took on ammunition, provisions, and fuel and headed back to the Marianas on the 15th. There, she resumed patrol and antisubmarine screening duties and kept at such tasks until the 25th when she moved inshore to provide gunfire support for the troops occupying Tinian.
