OAKLAND — The Oakland A’s now have a chance to exit the weekend series against the Houston Astros with a one-game lead in the American League West, and momentum is on their side. The A’s tied the game in the bottom of the ninth inning on a play at the plate, then Matt Olson launched his first career walk-off hit, a homer of Tony Sipp, in the bottom of the 10th for a 4-3 win over the division leaders at Oakland Coliseum on Friday night.

Olson pulled the A’s to within one game of the division lead after working a full count off Sipp. Sipp’s 3-2 pitch, a slider low in the zone just below the belt, found its way over the right field wall for Olson’s 23rd longball of the year and Sipp’s first loss of the campaign (1-2, 1.80 ERA). He almost didn’t get a chance for his heroics. The A’s trailed 3-2 heading into the bottom of the ninth inning. The leadoff man Mark Canha grounded out against reliever Hector Rondon to leave the A’s two outs away from defeat. Pinch hitter Chad Pinder walked, then was replaced by rookie Ramon Laureano, a pivotal substitution by A’s manager Bob Melvin.

The next batter, Nick Martini, laced a ball to right, with Laureano racing home from first. Josh Reddick’s throw home beat him to the plate and Astros catcher Martin Maldonado appeared to block off the plate perfectly to tag out Laureano as he dove headfirst across home. Home plate umpire Alfonso Marquez thought so, too, calling Laureano out.

The rookie, however, felt he had gained the plate legally, gesturing as soon as he rose from his slide. His manager challenged the play, and following a lengthy review, Laureano was deemed both correct and safe and Oakland was tied 3-3. Blake Treinen (6-2, 0.87 ERA) worked around a runner at second with two outs, while striking out three Stros to pick up his sixth win of the year.

The A’s had to play catch-up three times. They trailed 2-0 heading into the bottom of the fifth after starter Edwin Jackson gave up solo homers Alex Bregman and Maldonado in the fourth and fifth innings, respectively. They loaded the bases against Houston starter Charlie Morton with no outs, but Jonathan Lucroy only plated one runner on a double-play grounder. Matt Chapman would plate another run in the inning, but the big damage was avoided with the A’s forced to settle for the 2-2 tie.

The tie would be short-lived, as Houston scored in the top of the sixth. Lou Trivino struck out Carlos Correa but walked Marwin Gonzalez and Evan Gattis to put himself in trouble. Reddick capitalized against his former team, singling in Gonzalez. Trivino wriggled out of the jam trailing 3-2 after getting first baseman Tyler White to bounce into a double play.

The A’s don’t need to do any scoreboard watching if they want to lead the division by the end of play Saturday. They just need Trevor Cahill to take the bump and stymie the Houston batters. Oh, and they also need to beat Dallas Keuchel, a former Cy Young award winner.

The A’s and Astros will square off for game two Saturday afternoon at 1:05 pm PDT.
