Patton, who's represented by CAA Baseball, made $483,500 last season while going 1-0 with a 2.43 ERA in 54 games. Left-handers hit .212 against him.
Teams have until 1 p.m. to reach agreements with their arbitration-eligible players before the two sides exchange figures, with hearing dates set up next month.
Executive vice president Dan Duquette continues to work on deals with Chris Davis, Jason Hammel, Jim Johnson, Brian Matusz, Darren O'Day and Matt Wieters. The Orioles previously reached agreements on one-year contracts with Nolan Reimold and Tommy Hunter.
I'll update this entry later today.
Update: See, I told you.
The Orioles and Wieters have reached agreement on a $5.5 million contract for 2013, according to CBSSports.com.
Wieters, who's represented by Scott Boras, reportedly will also receive $100,000 if he wins a Gold Glove, $75,000 if he's named to the All-Star team and $75,000 if he wins a Silver Slugger. He took home a Gold Glove and made the All-Star team in 2012.
The Orioles renewed Wieters' contract for $500,000 in spring training, causing a brief stir in camp, and he responded by batting .249/.329/.435 with 27 doubles, 23 homers and 83 RBIs. He finished 21st in Most Valuable Player voting.
Wieters, 26, easily exceeded Russell Martin's first-time catcher arbitration record of $3.9 million, set in 2009.
Wieters has two more arbitration years remaining before free agency. Considering the raise he's receiving this season, it might be a good idea for the Orioles to start thinking about signing him to an extension.
Update II: The Orioles announced that they've also agreed to terms with Davis and Matusz on one-year deals.
The club exchanged salary arbitration figures with Johnson, Hammel and O'Day. The goal now is to get them signed before the hearing dates, which usually happens.
Update III: Davis will be paid $3.3 million, which is quite a jump from the $488,000 he made last season while batting .270/.326/.501 with 20 doubles, 33 homers and 85 RBIs.
Matusz will make $1.6 million in his first year of arbitration eligibility as a Super Two. He went 6-10 with a 4.87 ERA in 34 games, including 16 starts. Left-handers batted .175 against him and he posted a 1.35 ERA in 18 relief appearances.
Duquette and manager Buck Showalter have been reminding reporters and fans that the club needed to account for all these raises while also checking the free-agent market. Johnson also is in line for a significant raise after making $2.625 million last year.
The Sun first confirmed the salaries for Davis and Matusz.
