Jake Arrieta was masterful for three innings but unraveled in the fourth and the O's fell to the Rays 8-4 on Sunday afternoon.
It was the fourth straight series the Birds have dropped, and the loss gave Tampa Bay sole possession of first in the East.
Arrieta (2-7) continues to be a mystery this season, showing flashes of brilliance before falling apart. He lasted just 4 2/3 innings, surrendering four runs on just two hits but four walks, striking out three. The 'pen, overworked lately, gave up another four runs (only three earned...the O's committed three errors and lead the league with 51).
The Birds thankfully have Monday off before starting a three-game set with the Red Sox. Jason Hammel takes the mound at Fenway on Tuesday night.
