Oakland at Seattle

Seattle clinched a postseason berth for the first time in 21 years with a walk-off homer by Cal Raleigh with two outs in the ninth on Friday night to beat the Athletics 2-1. However, the Mariners still have work to do as they stayed 1 1/2 games behind Toronto for the top American League wild card and a half-game ahead of Tampa Bay. The Mariners have won three straight and Oakland has lost five in a row to put it at 101 losses for the season. Luis Castillo has a 2.79 ERA at home this season for Seattle and JP Sears has allowed 17 runs his past 14 2/3 innings pitched for Oakland, which is 23-49 versus teams with winning records and 15-40 on the road against winning teams. Seattle has won 22 of the past 29 meetings. Take the Mariners.
