Hey, at least the Giants got a run tonight.

Tyler Colvin’s solo homer in the seventh inning was the lone positive moment in yet another uninspiring performance by the Giants, who fell to the A’s 6-1 on Tuesday night.

As is the norm lately for both clubs, the A’s took advantage of miscues and rode their pitching to victory, while the Giants squandered opportunity after opportunity and dropped their fifth game in seven days a.

The A’s scored four times in the third inning, and it all started when Joe Panik couldn’t get out of Hunter Pence’s way on a pop fly to shallow right, allowing Jed Lowrie to reach first. Nick Punto doubled in Lowrie, Coco Crisp knocked in Punto with a single, and then he went to second after Gregor Blanco’s throw to the plate missed the cutoff man. As a result, Crisp was able to steal third and score on a broken bat single by Yoenis Cespedes.

See where I’m going here? The Giants didn’t commit any errors in the plays mentioned above, but their two subtle mistakes – Pence getting distracted by Panik and dropping a fly ball and Blanco missing the cut-off man – led to a four-run rally by the A’s, which was more than enough run support for Sonny Gray.

Gray threw seven strong innings, allowing just one run on six hits, striking out eight. The Giants got their fair share of hits with eight on the night, but were 0-for-9 with runners in scoring position.

Bay Bridge Bites

– Angel Hernandez was behind the plate tonight and … let’s just say it was a rough night, even for him. Besides the incredibly inconsistent and wide strike zone, which infuriated pitchers and hitters from both teams, Hernandez called a balk on Jean Machi in the eighth, allowing a runner to go from second to third. Machi was visibly upset and started yelling at Hernandez, prompting Buster Posey to get up and try to calm the situation. Hernandez then yelled, “Don’t push me” at Posey, although it’s downright ludicrous to imagine that Posey was trying to start an altercation with the umpire.

Bruce Bochy then went out and argued unsuccessfully, then sat down in the dugout just in time to watch the runner from third score on a single by Alberto Callaspo for the A’s sixth run.

I swear Bochy must be aging five years per game at this rate.

– Some numbers to visualize the Giants’ freefall:

– Even their All-Star pitcher, Madison Bumgarner, isn’t immune to the swoon. He allowed 10 hits and six runs in seven innings tonight, and this has been par for the course recently. After allowing just 16 earned runs from May 4 through June 22 (10 starts), he’s allowed 15 earned runs over his last three starts.
