Motter is out of the lineup Wednesday against the Nationals, Bob Dutton of The Tacoma News Tribune reports.
Motter's versatility had allowed him to make 12 consecutive starts at three different positions while the Mariners looked to plug multiple holes in the lineup, but his services won't be needed as frequently with Robinson Cano is back from the disabled list and Danny Valencia having recovered from a wrist issue. It will likely take another injury to one of the Mariners' key regulars in order for Motter to see a steady diet of at-bats.
