Baltimore Orioles starter Chris Tillman, who in the past year has transformed from promising arm to all-star, shut down a dangerous Oakland Athletics lineup through eight innings Saturday afternoon.

He held them to just one run over three hits, tying a career high with nine strikeouts with his fastball reaching 94 mph on his 115th and final pitch.

But the Orioles ended up wasting one of the 25-year-old’s best starts. Coco Crisp’s solo homer to lead off the top of the ninth off reliever Darren O’Day sent the Orioles to a numbing 2-1 loss before an announced 33,834 at Camden Yards.

The Orioles (69-59) had the opportunity to cut Oakland’s lead for the second American League wild-card spot to one game. Instead, they head into Sunday’s series finale three games behind the A’s (72-56).

Crisp sent a 3-1 slider from O’Day (5-3) onto the flag court in right.

Tillman held the A’s to one hit over his first five innings before the Athletics tied the game at 1 in the sixth on Jed Lowrie’s two-out RBI double.
