OAKLAND -- It’s easy to suggest that the Orioles did more to win Monday night’s series opener against the A’s than to lose it.

But ballclubs with winning percentages below .300 have a way of doing just enough to lose. Its good deeds might outnumber the bad ones, but the positive might not outweigh the negative.

Such was the case in the Orioles’ sixth consecutive defeat, a 3-2 decision at the Oakland Coliseum that featured a couple of miscues by catcher Chance Sisco.

Trey Mancini prolonged the first inning with a two-out single off A’s starter Mike Fiers and advanced to second base on a wild pitch. Sisco drew a walk, then saw Mancini break for third base while on the bases. Imagining the momentum the Orioles would gain by executing a double steal, Sisco took off for second. He was thrown out easily to end the mild threat.

Baltimore manager Brandon Hyde has seen such behavior before. He attributed the mistake to not “understanding the game a little better.”

“That’s just a couple of guys trying to make something happen that’s not there,” Hyde said, indicating that Mancini also should have stayed put. “We talked about it at the end of the inning. Obviously, I wanted [Pedro] Severino to swing the bat there.”

Said Sisco grimly, “[There was] no real miscommunication. Just trying to make something happen. In that situation, I saw Trey hopping off, so I thought I could follow him.”

An unusual throwing error by A’s third baseman Matt Chapman, the reigning Gold Glove Award winner, helped Baltimore score twice in the second inning and forge ahead.

Then Sisco endured a similar lapse in Oakland’s half of the third.

With the bases loaded, Baltimore third baseman Rio Ruiz scooped up Matt Olson’s grounder and threw home for a forceout. Sisco sensed an opportunity to convert a dynamic double play and fired the ball to first base, but his low throw skipped past Chris Davis. Marcus Semien scored and after a replay review, so did Chapman, who initially was called out at home.

“I caught the ball, tagged home, looked down the line and [Olson] was pretty close to first already, but I rushed the throw,” Sisco said. “I just have to make a better throw in that situation.”

Hyde again summarized the play succinctly.

“It’s a little bit like the double steal -- trying to make things happen instead of letting the game come to us,” Hyde said. “[Not] understanding the speed of the game and he tried to force it a little bit.”

The Orioles’ night was basically over at that juncture, since they mustered only one hit through the final seven innings off Fiers (7-3) and two relievers. A solid outing by Orioles starter Andrew Cashner (6-3), who surrendered four hits in six innings and was charged with one earned run, went to waste.

Cashner indicated that he remained mindful of the blistered finger that forced him to miss a recent start.

“It was there,” he said. “But I was able to grind through it.”
