The Seattle Mariners made one of the first big moves of the offseason by acquiring outfielder Teoscar Hernández from the Toronto Blue Jays in exchange for two pitchers.
Robbie Ray was tagged for home runs by Shea Langeliers, Cristian Pache and Nick Allen, and the Seattle Mariners hopes of hosting the AL wild-card series took a serious blow in a 10-3 loss to the Oakland Athletics.
Teoscar Hernández belted a pair of three-run homers over the Green Monster, two of the Toronto Blue Jays' eight homers in an 18-4 rout of the Boston Red Sox.
