They haven't lost 100 games in a season since 1983, when they dropped 102 - but the Mariners are sprinting toward that plateau this year.
Seattle has lost a sesason-high 12 consecutive games going into this one, tying the franchise record for the second-longest losing streak.
What was worse, you ask? A 14-game losing streak in 1992.
Ryan Feierabend starts, and the last five men in the Mariners lineup - Jeremy Reed, Wladimir Balentien, Matt Tuiasosopo, Kenji Johjima and Luis Valbuena - have a combined 81 RBI.
Here it comes: Mariners vs. Angels.
Ryan Feierabend was putting on a clinic, retiring the first five Angels he faced, using everything from 90 mph fastball to a 74 mph change.
It looked easy, even after he gave up a two-out single in the second inning. Then Gary Matthews Jfr. hit one into the right center field stands - home run #8 for Matthews - and Feierabend was behind.
Angels 2, Mariners 0
Ichiro Suzuki, who leads the majors with 175 singles - the next highest total by a player is 146! - followed a Kenji Johjima single with a double to right.
Yuniesky Betancourt then blooped a ball into short center field for a two-run single and, after three innings, it's even.
Mariners 2, Angels 2
Mike Napoli untied it with one of the longest home runs of the year - a 447-foot shot off the batters eye beyond center field.
Unfortunately for Feierabend, there were two men on base at the time
It's been a struggle, the last two innings, and Feierabend left after throwing 84 pitches.
Sean Green now pitching for Seattle.
Angels 5, Mariners 2

Matt Tuiasosopo got a smallish Safeco Field crowd pumped, leading off the fifth inning with a triple that banged off the wall in the left field corner.
Mariners fans know the rest.
Johjima popped out. Valbuena struck out. And Ichiro was thrown out trying to bunt for a base hit.
Tuiasosopo was left at third.
Angels 5, Mariners 2
Looking for subtle differences between the first-place Angels and last-place Mariners?
An inning after Seattle left a man at third base, the Angels stole a run.
Chone Figgins singled and took second on Garret Anderson's single. When Mark Teixeira flied out to left field, Figgins tagged - and left fielder Wladimir Balentien caught the ball going backwards.
Figgins easily beat a belated throw to third, then scored on a fly ball.
Angels 6, Mariners 2
The Mariners rallied in the sixth, and forgive the Angels for shaking their heads about it.
After one-out singles by Raul Ibanez and Jose Lopez, Reed hit a one-hopper sharply back to the mound - and Jered Weaver clanked it so badly it wound up in short right field.
Charitably ruled a single, it drove in Ibanez.
Balentien then flied to center field, just short of the warning track, and Torii Hunter simply didn't get to the right spot. The ball fell beside him for an RBI double.
Johjima, a dead-pull hitter, doubled to right center field and - what's this? - the Mariners had tied it again.
Kevin Jepsen in to relieve Weaver.
Mariners 6, Angels 6
Jeremy Reed, the outfielder the Mariners got in the Freddie Garcia trade in 2004, singled home the go-ahead run in the seventh inning - the 97th RBI of his Seattle career.
Yuni singled to open the inning, stole second and stayed put when Ibanez walked. Reed then singled into right center field, and he Mariners had their first lead of the night.
Balentien grounded to shortstop, but Erick Aybar misplayed the ball - Balentien was safe and Ibanez scored.
Jojhjima singled to right field. Yes, right field, and pushed home a third run.
It's not pretty, and it hasn't all been their fault, but Seattle leads.
