KANSAS CITY, Mo. (AP) - Marcus Semien provided just enough early offense and Mike Fiers and three Oakland relievers combined to shut down the Kansas City Royals in a 2-1 victory Tuesday night.
Semien had hits in his first two at-bats of the game, coming around to score in the first inning and driving in a run in the second. That was all the offense the A's pitchers needed.
Fiers looked solid through five innings, but ran into a bit of trouble in the bottom of the sixth. Alex Gordon had an RBI double into the gap in right-center. After striking out Cheslor Cuthbert, a walk to Ryan O'Hearn ended Fiers' night. Yusmeiro Petit came in and retired the next two batters, striking out Meibrys Viloria, to escape the jam and preserve the 2-1 lead.
Fiers (13-3) scattered eight hits in his 5 1/3 innings, but allowed just the one run and struck out five batters. He's now won 11 straight decisions, dating to May 7, tying Mark Mulder for the second-longest winning streak in Oakland history.
Petit retired all five batters he faced. Joakim Soria tossed a scoreless eighth and Liam Hendriks worked the ninth inning for his 16th save in 20 opportunities.
The A's have won 10 of their last 13 games in Kansas City and 16 out of the last 21 overall, outscoring the Royals 140-62 in that span.
Mike Montgomery (3-7) shook off a shaky start to put together another quality outing, despite struggling again with his command. Montgomery surrendered an unearned run in the first and another run in the second, but gave up nothing else through 6 1/3 innings. He walked three batters and hit another and has now issued eight walks over his last three starts after walking three total in his first five starts with the Royals.
The A's didn't hit the ball out of the infield in the first inning, but still managed to squeeze out a run after Cuthbert's error extended the inning. A walk to Chad Pinder two batters later drove in Semien.
An inning later, Semien laced an RBI single to right field, scoring Josh Phegley who doubled two pitches earlier.
Whit Merrifield and Gordon both had two-hit nights for the Royals.
BROWN SHOWS OFF DEFENSIVE SKILLS
A day after making his big league debut by getting hits in his first two at-bats, A's left fielder Seth Brown flashed his defensive abilities. With one out in the bottom of the second, Brown raced towards the left-center gap and made a diving catch to rob Cuthbert of extra bases. In the third inning, Brown threw out Viloria, who was trying to score from second on Merrifield's single.
