Severino retired Stephen Biscotty on a fly ball to right, but then loaded the bases with a six-pitch walk to Ramon Laureano in which he seemed to get squeezed by the home plate umpire, Jim Wolf, on a potential strike three. But Severino showed some moxie, recovering to strike out Marcus Semien to end the inning.

Severino has seven strikeouts and four walks, and is up to 81 pitches.

David Waldstein: Andujar’s error highlights one area — corner infield defense — where the A’s have the advantage. Matt Chapman is as good as anyone at third base and first baseman Matt Olson excels at scooping balls out of the dirt, saving numerous runs during the course of the regular season. And the A’s rely on him. Olson played in all 162 games, the first American League first baseman to do that since Carlos Delgado in 2000.

If the Yankees hold this lead into the late innings, there is a good chance Aaron Boone will pull Andujar and Voit in favor of Adeiny Hechavarria and Neil Walker.

Bottom 4th: Trivino Keeps Cruising

Maybe Lou Trivino is more than a reliever? The rookie pitched a third scoreless inning — matching the longest outing of his major league career — looking absolutely dominant while retiring Giancarlo Stanton, Luke Voit and Didi Gregorius as if they were bottom-of-the-order hitters. The strikeouts of both Voit and Gregorius gave Trivino four in three innings, and he has allowed just one hit.

Trivino has now faced 10 Yankees batters. He is one short of his career-high of 11 and the A’s are in somewhat unexpected territory as they were not expected to allow any of their relievers to face the same batter twice.

David Waldstein: The bullpen strategy is working for Oakland now with Trivino dominating through three innings. The bullpen part of it is working. The opener part — with Liam Hendricks giving up two runs in the first inning before he recorded an out — not so much.
