BALTIMORE—Matt Harvey’s season with the Orioles might be over. The Orioles placed the 32-year-old right-hander on the 10-day injured list because of right knee inflammation and recalled infielder Richie Martin from Triple-A Norfolk on Thursday.

Harvey, who started Wednesday night’s 9-8 Orioles win, has a 6-14 record with a 6.27 ERA. His 28 starts and 14 losses tie him for the American League lead.

Signed to a minor league contract before spring training, Harvey won a job and a $1 million major league contract. He recorded three straight wins from April 20^th-May 1^st.

He then lost 10 straight decisions before he won three more from July 18^th-30^th, pitching 18 1/3 shutout innings, allowing just 10 hits.

On August 4^th, Harvey left a start at Yankee Stadium because of a knee injury and hasn’t won since. On Wednesday night, Harvey allowed four runs, one unearned, on nine hits in 4 1/3 innings.

Because the Orioles have a number of young pitchers they’d like to see — Keegan Akin, Mike Baumann, Chris Ellis, Zac Lowther, Alexander Wells and possibly Dean Kremer — it’s possible that Harvey might not pitch again for the Orioles.

Martin played 15 games with the Orioles last month and hit .227 with a home run and five RBIs. His addition is timely because Ramón Urias, who contributed a key pinch-hit in the Orioles’ nine-run eighth inning on Wednesday night, hasn’t started since Sunday because of an upper leg injury.

Martin missed much of the season because of a broken left wrist. In 27 games with the Tides, Martin ws hitting .208 with a home run and five RBIs.

Notes: Trey Mancini, who missed three games because of an oblique injury returned to the lineup Thursday night. … Ellis will start the first game of the Orioles’ series against Toronto on Friday night against Robbie Ray. Akin will start one of the games of Saturday’s doubleheader, and manager Brandon Hyde said the team hasn’t decided on the other Saturday starter or Sunday’s. They’ll call up an extra player for the doubleheader. … Ellis has been charged with a hit in his five-inning start against the Yankees last Saturday. Aaron Judge’s liner that was dropped by leftfielder Ryan McKenna was scored an error, but it was changed to a hit. Ellis had been credited with five no-hit innings.
