Luis Robert Jr. not only stole the 100th base of his career, he went 3-for-4 with a walk and extended his on-base streak to 23 games. All of which just gave him the chance to … be stranded four times.

But let us pick up the game in extra innings. To set the scene, the Mariners took an early 2-0 lead when Shane Smith made one of his few mistakes on the day and hung a curve that Randy Arozarena deposited 380 feet away with a man aboard. Otherwise Smith had a solid five innings, pushing the limit when he usually wears down at 78 pitches, but not before he set a personal best with eight strikeouts.

Seattle starter Logan Gilbert, he of usually flawless control, actually walked three Sox in five innings, which is about a month’s worth of free passes for him. He also was wild in the zone, as they say, and Michael A. Taylor took advantage for a 106.4 mph solo shot to make it 2-1. Needing 94 pitches to get through five innings, Gilbert’s day was done.

As was the case the first two games of the series, the Sox fared better against the bullpen, Brooks Baldwin edging a scraper over the wall in right to tie the game in the seventh.

You may have noticed that both White Sox dingers were solo jobs. Meanwhile, what seemed like a hundred runners got stranded when a simple single would have sufficed to win the game. Fortunately, relievers Jordan Leasure, Bryan Hudson, Grant Taylor and Tyler Gilbert shut down Seattle through nine, albeit with Taylor letting runners get to second and third with one out in the eighth before notching two strikeouts, including Eugenio Suarez.

NOW, BACK TO THE EXTRA INNINGS

While the Mariners were both the better team and at home, in extras the Sox held an advantage in that Josh Naylor had left the game early having apparently hurt himself on a swing and Cal Raleigh had been removed for a pinch-runner in the eighth, making Dan Wilson scrape the end of his bench and use every position player on the team.

Top half, the Sox got a run about as cheaply as you can get one. With Lenyn Sosa as the Manfred Man, Andrew Benintendi and Robert failed to even move him to third for the first two outs, but then Seattle decided to intentionally walk the hitless Colson Montgomery to get a righty-righty matchup — only Eduardo Bazardo hit newcomer Curtis Mead where hand meets nub of bat to load the bases, after which Bazardo winged one to the backstop to let Sosa score without the benefit of the Sox having done a single thing to accomplish the run.

OK, so that was about as cheap as a run can be.

But there are other really cheap runs available. In the bottom half of the 10th, Miles Mastrobuoni tried to bunt Manfred Man Arozarena to third but Josh Rojas, in as a defensive replacement for Baldwin at third, threw the ball way into right field, letting the run score (why is this man on the team — even were he not so godawful, why is he taking innings from youngsters who might have a future?). Tie game, man on second, no outs, but the Sailors were almost as feeble as the Sox with RISP — they ended up 1-for-11 — and rolled over and played dead, so on to the 11th.

In the top half the Sox went down a quick 1-2-3, getting the total with RISP a ridiculous 1-for-17. In the bottom half Dominic Canzone singled to right with one out, and even though the runner was the pretty slow Suarez Mike Tauchman charged the ball nicely but then dribbled the throw home and the Mariners won, 4-3.

So, swept in the great northwest, the record falling to 42-73. The White Sox head back home, facing Cleveland and Detroit.
