Adam Jones has signed a six-year, $85.5 million contract with the Orioles, 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," Jones said. "I'm not from Baltimore. This is now my town." Jones extended his hitting streak to 18 games with a double in Sunday's loss and leads the team in home runs and RBIs.

The Yankees have signed former Mets right-hander John Maine to a minor-league contract. Maine, who hasn't pitched in the major leagues since 2010, is expected to provide organizational depth for New York. "He's interested in trying to get back to the big leagues, so we will see," Brian Cashman said. The Yankees also recently looked at Armando Galarraga.

Armando Galarraga has signed a Minor League contract with the Astros. The right-hander was famously denied a perfect game two years ago when umpire Jim Joyce missed a call at first base that would have been the final out. Galarraga, 30, will help the Astros fill a rotation spot at Triple-A Oklahoma City, which has a need for a starter after Henry Sosa agreed to pitch in Korea.

The Braves have signed outfielder Felix Pie out of the independent leagues. Pie has been assigned to Triple-A Gwinnett.

Vladimir Guerrero on Thursday signed a minor league deal with the Blue Jays, according to an ESPN.com report. If he passes a physical, Guerrero will play in some minor league games before being promoted to the major league level, where he will earn a prorated portion of a $1.3M salary.

The Dodgers have signed Bobby Abreu, one week after the outfielder was cut loose by the Angels. Abreu hit .208 in 24 at-bats before the Angels let him go last Friday.

The Reds have signed right-handed reliever Michael Wuertz to a Minor League deal.

The Red Sox have signed pitcher Mark Prior to a minor league deal. Prior was the second overall pick in the 2001 draft by the Cubs, but arm injuries curtailed his career. He hasn't pitched in the big leagues since 2006, and has thrown only two innings as high as Triple-A since then.
