DETROIT - The A’s plan to promote top prospect Sean Manaea, a 24-year-old left-hander acquired from Kansas City in the Ben Zobrist deal, to start Friday at the Coliseum, according to multiple sources.

Manaea is putting up sensation numbers at Triple-A Nashville, where he has allowed 16 hits, three runs and four walks in 18 innings - while striking out 21. He had been scheduled to start Thursday for Nashville so will be working on an extra day of rest against the Astros.

Opponents are batting .232 against Manaea - and left-handed hitters just .077.

Jesse Hahn, who was in Oakland’s rotation last year before a forearm ended his season, was the other consideration for Friday’s start after Eric Surkamp was demoted on Monday, but Hahn is dealing with a blister issue. He’s also pitching well, with a 2.04 ERA at Nashville, but he’s walked nine and allowed 16 hits in 17 2/3 innings.
