Missouri's bats had been held silent through four-plus innings against Auburn right-hander Tanner Burns.
Senior right-fielder Trey Harris soon flipped the script and left Auburn's fans silent instead.
Harris uncorked a two-out grand slam in the fifth after an error and pair of walks sparked a rally, and Missouri hung on for a 5-0 win over No. 13 Auburn in the series finale Sunday in Auburn, Alabama.
Harris, who drove in all five MU runs, homered for the second time in the series against Auburn and extended his career-best streak of reaching base to 20 games.
