CINCINNATI (AP) Mariners shortstop Ketel Marte left in the fifth inning on Saturday because of sprained left thumb.
Seattle's leadoff hitter had an infield single and slid hard while stealing second base off Cincinnati's John Lamb. He also stole third base and was stranded there. He went into the dugout during the half-inning and stayed there, with Shawn O'Malley replacing him in the field.
There was no immediate word on the severity of the injury. The Mariners led the Reds 4-0.
