Jesse Hahn allowed seven runs in the first inning, dooming the Athletics early in a 12-2 road loss to the Houston Astros Friday night to end a five-game win streak. Houston (26-) also touched up mop-up man Andrew Triggs for five runs, with Evan Gattis knocking in four runs and Colby Rasmus and Tony Kemp knocking in a pair each to move ahead of Oakland (25-30) a half-game out of the AL West cellar. Marcus Semien hit his eleventh homer of the season while Billy Butler plated a run with his RBI double.

Hahn (2-3, 6.10 ERA) failed to retire three of the first four batters he faced but allowed only one run to that point on Rasmus’ RBI single. Evan Gattis ground out to second to push Jose Altuve across for a 2-0 lead. The A’s starter would fail to retire the next five hitters he faced, including a two-run triple by Tony Kemp, to get the hook from manager Bob Melvin with his team trailing 7-0. Long man Triggs came in and worked around a single to punch out Carlos Correa and end the inning with the Astros batting around the order.

Triggs surrendered a pair of runs in the fourth on a two-run shot by Gattis then gave an RBI single to Correa to exit the game with two outs in the fifth inning, two runners on and Oakland trailing 10-0. Marc Rzepcynski came on for Trigg, but allowed a pair of inherited runners to score on singles by Rasmus and Correa.

On the other side of the blowout, Doug Fister (5-3, 3.51) pitched six innings of four-hit ball for his fifth win of the season. The former Mariner and Tiger struck out three while walking a pair. He made way for Tony Sipp in the seventh, allowing the A’s to finally break through.

After battling Fister to an 18-pitch at-bat earlier in the game to no avail, Marcus Semien came through in the seventh. He greeted Sipp with a deep fly to left field for season homer number 11. He was replaced by Chris Devenski in the eighth inning. The righty allowed back-to-back doubles to Stephen Vogt and Billy Butler for the A’s second and final run.

Saturday’s game will be doubly challenging for the A’s with intended starter Rich Hill being scratched from his start with a groin injury. Kendall Graveman will be moved up a day in the rotation to take on Collin McHugh. Oakland hopes to avoid having another position player take the mound, as they did Friday with utility man Tyler Ladendorf making his pitching debut.
