Vosler will start at first base and bat seventh in Monday's game against the Red Sox.
Vosler will pick up his fifth start in six games Monday, but his run of steady playing time will likely soon come to an end. The Mariners have acquired two everyday players in Randy Arozarena and Justin Turner within the past few days, and Vosler looks to be one of the Mariners regulars most at risk of losing out on work as Seattle clears room in the lineup for the new arrivals. Vosler has gone 4-for-18 with two extra-base hits, one walk, two RBI and two runs since getting called up from Triple-A Tacoma last Monday.
