Baltimore Orioles left-hander Wade Miley had it all laid out. The Orioles scored five runs in the first inning and did it in historic fashion, seemingly setting the tone for an upbeat fireworks night at Camden Yards.

Instead, the game blew up faster than any of the exploding rockets that were shot into the sky following the game. The Orioles suffered a particularly distasteful 15-8 loss Friday night to even the four-game series at a victory apiece.

It isn’t supposed to be heavy lifting when your teammates give you four home runs before they make their first out, but shutdown innings have been elusive for the Orioles’ rotation this season and that certainly was the case when the Houston Astros came up for their second time at bat.

Miley, who had an 0-2 record and 7.04 ERA in his three previous Orioles starts, allowed a leadoff home run to George Springer to begin the game but struck out five of the next six batters before it all went south.

With two outs and one runner on in the second, he let five straight hitters reach base — four of them hitting safely to drive in runs. The unkindest cut of all came from MVP candidate Jose Altuve, who slapped a two-run double down the right field line to complete a five-run comeback and give Houston a 6-5 lead.

Miley allowed six earned runs in 12/3 innings.

The Orioles came back to regain the lead with two runs in the third, only to have Ubaldo Jimenez surrender three runs over three innings of long relief.
