Segura was pulled from Monday's game after straining his right hamstring, Shannon Drayer of MyNorthwest.com reports.
Segura was forced to exit the game after he injured himself diving back to first base in an attempt to avoid a double play. He will be reevaluated Tuesday to see whether a move to the disabled list is warranted, but for now, the Mariners are hoping he will only be day-to-day. With Shawn O'Malley on the DL, Taylor Motter appears to be the likely replacement for Segura if he should miss extended time.
