Seattle Mariners 4, Los Angeles Angels 6

Two weak offenses meet in Anaheim. Los Angeles is 56-92 with a .680 OPS; Seattle is 70-79 at .692, and their season scoring rates are separated by a single hundredth of a run. Recent form diverges, though — the Mariners have scored 5.70 runs per game over their last ten despite a 4-6 record, while the Angels have gone 3-7 on 3.60.

Reid Detmers is the reason to watch. His season line is already strong — a 3.32 ERA, a better 3.03 FIP, a 1.04 WHIP, 10.2 strikeouts against 2.4 walks per nine, and quality starts in 48% of his outings — and his last five have been close to untouchable: a 0.55 ERA with 9.5 strikeouts against 0.5 walks per nine, going 6.2 innings per start. That is the single best recent stretch of any pitcher on this slate. Kade Anderson arrives with 21 innings across four starts, a sample the data flags as unusable, and the little that exists is unpromising — a 4.29 ERA against a much worse 5.19 FIP, with 1.7 home runs allowed per nine.

Handedness sharpens the edge: Detmers throws left-handed, and Seattle carries a .637 OPS against lefties, the lowest such figure in today's data, although the sample behind it is thin. The bullpens are effectively level at 4.35 and 4.55, and both have thrown around seven innings in three days. Angel Stadium plays neutral at 68°F.
