The Seattle Mariners (33-31) and the Arizona Diamondbacks (31-34) open a 3-game series at Chase Field in Phoenix Monday. First pitch is scheduled for 9:40 p.m. ET (FS1). Let's analyze BetMGM Sportsbook's MLB odds around the Mariners vs. Diamondbacks odds and make our expert MLB picks and predictions for the best bets.

It's Monday, June 9, and the Mariners (33-31) are in Phoenix to take on the Diamondbacks (31-34). Emerson Hancock is slated to take the mound for Seattle against Merrill Kelly for Arizona. The Diamondbacks were swept by the Reds after a 4-2 loss yesterday.

The Seattle Mariners currently sit outside of the playoff picture, having just dropped five in a row to the Orioles and the Angels. A playoff team should have swept those series rather than going 1-5, and doing so would have Seattle delightfully positioned atop the AL West.
