Even though Adam Jones isn’t from Baltimore, he’s making sure it’ll be home for a while longer.

Jones signed a six-year $85.5 million contract with the Orioles on Sunday, ensuring that the 26-year-old center fielder will be with the team through 2018.

“I fit here in this city. I fit here on this team. I fit in Camden Yards. I don’t see myself wearing another white uniform that doesn’t have Orioles across the chest,” said Jones, a native of San Diego.

“I’m not from Baltimore. This is now my town.”

A fan favorite, Jones extended his hitting streak to 18 games Sunday and leads the team in home runs and RBI.

Dan Duquette, vice president of baseball operations, began negotiating a new deal with the 2009 All-Star weeks ago.

Jones’ deal includes a $2 million signing bonus, $8.5 million in 2013, $13 million each in 2014 and 2015, $16 million apiece in 2016 and 2017 and $17 million in 2018. It also includes a no-trade provision.

After the Orioles and Jones agreed on a one-year, $6.15 million contract in February, avoiding arbitration, they began exploring an extension.

“We started the process in spring training, and picked up some steam in the last couple of weeks,” Duquette said.

Jones has been active in community affairs, something that Duquette referred to several times during Sunday’s announcement.

“To have a great team in Baltimore, you have to find and keep players like Adam,” Duquette said.

Shoulder forces Phillies’ Halladay out

Philadelphia Phillies pitcher Roy Halladay left his start Sunday against the St. Louis Cardinals after two innings as a precaution because of right shoulder soreness, matching the second-shortest outing of his career.

A team spokesman said Halladay would be re-evaluated in the next few days. Joe Savery replaced Halladay, who entered with a 4-4 record and 3.58 ERA.

Cards’ Jay leaves for rehabilitation

St. Louis Cardinals outfielder Jon Jay, on the 15-day disabled list with a shoulder injury, is leaving for extended spring training in Jupiter, Fla., and could return to action soon.

He’s batting .343 with two homers and eight RBI in 27 games.
