Zach Eflin has provided a huge lift to the Orioles since his arrival in a trade with Tampa Bay. It was their turn to pick him up. They owed him. They had numerous chances. Eflin served up leadoff home runs to Yandy Díaz in the first inning and Taylor Walls in the third, and the Orioles couldn’t deliver in the clutch in a 7-1 loss to the Rays before an announced crowd of 34,256 at Camden Yards, where rain held up the start for 27 minutes.
