The Seattle Mariners are playoff contenders and should be buyers at this year’s trade deadline. At 42-39, Seattle holds the third American League Wild Card spot and is six-and-a-half games behind the Houston Astros for first place in the AL West. The Mariners are usually a stronger pitching team with a weak offense, but this season is different. Seattle’s offense is top 10 in Major League Baseball thanks to Most Valuable Player candidate Cal Raleigh.
