The Seattle Mariners are in the middle of a skid that has the potential to get significantly worse. The Mariners are 33-34, have been swept twice in their last three series and are four games behind the Houston Astros in the American League West as of Thursday.

Eugenio Suarez hit his third grand slam of the season, Pavin Smith also homered in a five-run sixth, and the Arizona Diamondbacks completed a three-game sweep of the Seattle Mariners with a 5-2 victory on Wednesday afternoon in Phoenix.

Eugenio Suarez's grand slam puts the Diamondbacks up 4-2 on the Mariners. ESPN BET Sportsbook is owned and operated by PENN Entertainment, Inc. and its subsidiaries ('PENN'). ESPN BET is available in states where PENN is licensed to offer sports wagering.
