The A’s moved within 1.5 games of the AL West-leading Astros.

Ramon Laureano drew a one-out walk from Roberto Osuna (1-2), Jonathan Lucroy singled and Martini followed with his double.

Osuna said he was trying to go up and in but he missed down the middle. He was most disappointed in the walk to Laureano.

Martini misplayed a fly ball by Josh Reddick and then overthrew second in the eighth inning of Monday’s 11-4 win by the Astros, but tonight he quickly got over his miscue and came up with another big hit against Houston.

Martini also hit a tying RBI double in the ninth against Houston on Aug. 17.

Jeurys Familia (8-4) pitched a scoreless eighth. Blake Treinen worked a perfect ninth for his 33rd save. Oakland’s bullpen threw 4.1 scoreless innings.

Houston took a 1-0 lead in the second on a groundout by Tyler White, scoring Carlos Correa.

Matt Olson hit a three-run homer that gave Oakland a 3-1 lead in the third. Charlie Morton walked Jed Lowrie and hit Khris Davis with two outs before Olson’s 24th home run of the season.

Alex Bregman’s two-out, two-run double in the Houston fifth off Edwin Jackson made it 3-all.

Morton allowed three runs on three hits with four walks and three strikeouts in 4.2 innings.

Jackson gave up two earned runs and four hits with four strikeouts in 4.2 innings.

For today’s series finale, the Athletics will go with right-hander Trevor Cahill (5-3, 3.44 ERA), who is 1-3 with a 6.92 ERA on the road this season. The Astros will send left-handed pitcher Dallas Keuchel (10-10, 3.54) to the mound. He will be seeking his second straight win after allowing two runs over seven innings in his last start Friday at the Angels.
