Muncy went 2-for-3 in Saturday's 5-1 loss to the Yankees.
The 25-year-old notched his first start since being called up from Triple-A Nashville on May 17, and responded with a pair of singles on an afternoon when the A's bats were largely silenced by Masahiro Tanaka. The productive performance is an extension of the solid resume that Muncy was building to date this season at the minor league level, as he'd slashed .279/.399/.459 over 122 at-bats in his Triple-A stint.
