The Seattle Mariners (21-26) and Oakland Athletics (28-20) play the first of a three-game set Monday at RingCentral Coliseum with a 9:40 p.m. ET first pitch. Let’s analyze BetMGM Sportsbook‘s lines around the Mariners vs. Athletics odds with MLB picks and predictions.
LHP Yusei Kikuchi is the projected starting pitcher for the Mariners. He is 1-3 with a 4.32 ERA, 1.10 WHIP, 9.5 K/9 and 3.1 BB/9 over 50 IP through 8 starts.
Kikuchi was pushed back by manager Scott Servais, giving the southpaw an extra day of rest since he hasn’t been feeling well recently. He has posted four straight quality starts, but he hasn’t won since April 29. The Mariners offense has provided him with just 6 runs of support during the four-game span.
RHP Frankie Montas is the projected starting pitcher for the Athletics. He is 5-3 with a 4.79 ERA, 1.40 WHIP, 8.6 K/9 and 2.5 BB/9 over 47 IP through 9 starts.
Montas has allowed three or fewer runs in each of his past 5 starts. He coughed up 2 earned runs, 7 hits and 2 walks with 6 strikeouts in 5 innings in a loss against the Astros, snapping a three-start win streak.

Run line/Against the spread (ATS)
The ATHLETICS -1.5 (+125) are worth a look at home, based on their solid numbers in the series. They have won four of the past five meetings with the Mariners in the Bay Area, and Seattle is also 0-4 in their past four series openers, too.
Over/Under (O/U)
The OVER 7.5 (-105) has consistently cashed for both of these teams recently. Yes, the Mariners have not given Kikuchi very good run support of late, but the Over is 7-0-1 in the past eight games on the road for the M’s. The Over is also 5-1 in the past six games inside the division.
The Over is still 7-1 in the past eight games overall for the A’s, and 4-1 in the past five games at home. The Over is also 19-7-1 in the past 27 divisional games for the A’s.
