The window might be shut tight permanently on any possibility that the Orioles and starting pitcher Chris Tillman come to a long-term agreement, CBSSports.com Baseball Insider Jon Heyman is reporting.

The two sides never came close to hammering out a contract. And Tillman seems to be wiping out any opportunity with his performance on the mound. He opened the season as the ace but hasn't pitched like one.

Tillman is 2-6 with a 5.59 ERA and has walked 25 in 48 1/3 innings. He has lost his last five decisions, though his last start against Houston was arguably his best of the year.
