Mariners 4, Athletics 3

Money line (ML)

Athletics pitchers owned an 11-game 2.52 ERA until running into the Mariners in Monday’s series opener. Now, Oakland has dropped the first two games of this series, while yielding 13 runs Monday and 4 Tuesday. The A’s are 3-6 since Sept. 20, and their slip has all but officially knocked them out of the playoff picture.

The Mariners are 13-6 with an improved .748 OPS since Sept. 8. Their .689 OPS for the season ranks 26th in the league.

Seattle is 14-4 over 18 games against the A’s. The Mariners have flummoxed analytics observers (including this one) by being 18 games over-.500 while scoring 4.32 runs per game and allowing 4.64; however, the starter matchup — and the somewhat false perceptions on both sides — play into a Seattle lean Wednesday.

BACK THE MARINERS (-110).

Run line/Against the spread (ATS)

PASS on the juice-drowned run-line prices.

Over/Under (O/U)

Statcast quality-of-contact numbers tell the story of two offenses a bit too far out over their skis. There is also some play to Gilbert (hurt by a 66.6% left-on-base figure) and both bullpens being better than surface numbers indicate.

BACK THE UNDER 7.5 (-125).
