Frighteningly, Rooker didn’t even have the best day of any Athletics player. First baseman Seth Brown also launched two homers, and right fielder Lawrence Butler topped them both by hitting three balls over the fence.

Zack Gelof also contributed a home run, but since he didn’t hit any others in the game, it barely feels worth mentioning.

It would be easy to blame the entire mess on Mercado, who does not appear to be a major league quality pitcher at this point in time. Sadly, Mercado wasn’t alone in his ineffectiveness. Seranthony Dominguez gave up four runs in 1.1 innings, Jose Ruiz allowed three runs in his one inning of work, and catcher Garrett Stubbs was asked to handle the ninth inning, in which he allowed five runs.

The Phillies probably weren’t going to win no matter how well the offense performed, but it was still a disappointing showing from the lineup. Matched against underwhelming starter Joey Estes, they didn’t get much going at the plate. They scored two runs on a sixth inning sacrifice fly by Bryson Stott and an ensuing throwing error. But for most of the day, they looked as if they couldn’t wait for the All-Star break to begin.

It’s a disappointing finish to an otherwise excellent first half, but it should not be cause for panic. At worst, they’ll head into the break with an 8.5 game lead in the division, which is the biggest in baseball. They just need to flush this one, enjoy a few days off, and come back strong to start the second half.
