Moeller among non-roster invites

Simon, Hinckley, Arrieta also on list for O's spring camp

BALTIMORE -- The Orioles released a list of non-roster invitees to their Spring Training camp on Wednesday, further swelling their roster and adding some interesting names to the mix. Baltimore added 12 veterans -- seven pitchers and five position players -- eight of whom have Major League experience and should add quality depth for the Grapefruit League schedule.

Perhaps the most familiar names on the list are Chad Moeller and Alfredo Simon, both of whom were on last year's Opening Day roster. Simon started the season in the rotation, but was shut down early and eventually had season-ending ligament replacement surgery on his pitching elbow, while Moeller served as backup catcher to both Gregg Zaun and later Matt Wieters.

The Orioles have also invited left-handers Chris George and Mike Hinckley to camp, giving the team relievers who can work multiple innings during the Spring Training schedule. George hasn't pitched in the Majors since 2004 and racked up a 4.06 ERA among three Minor League teams last year, while Hinckley has had success in short stints with the Nationals.

Baltimore will also invite Jake Arrieta, one of the team's top pitching prospects, to Spring Training. Arrieta watched both Chris Tillman and Brian Matusz make the big league leap last year and will likely get his chance at some point in 2010. The Orioles also invited Minor League veterans Frank Mata, Josh Perrault and Ross Wolf to round out the pitching contingent.

The O's already have Wieters and offseason acquisition Craig Tatum on the 40-man roster, but they also invited Michel Hernandez and prospect Caleb Joseph to handle the catching duties at camp. Hernandez spent the past two seasons with Tampa Bay, while Joseph was named an All-Star in the Class A Carolina League after hitting .284 with 12 home runs and 60 RBIs.

Scott Moore, who missed much of last season with a torn ligament in his right thumb, is the lone infielder invited from off the roster. And Jeff Salazar, who has played for the Rockies, D-backs and Pirates, was the only extra outfielder. That shallow crop reflects the team's depth on the big league roster and the lack of positions up for grabs at Spring Training.

Baltimore's pitchers and catchers report to Spring Training on Feb. 17, and the team will hold its first full-squad workout on Feb. 23. Andy MacPhail, the team's president of baseball operations, said Tuesday that the Hot Stove season has pretty much gone as he'd anticipated and that the Orioles are still in the market for either a first baseman or a third baseman.

"We think there are some pretty good players still on the board at those positions," said MacPhail, who signed Garrett Atkins earlier this offseason. "We've done pretty much what we said we were going to do. We said we would let things percolate and then get back to it. I would think that we'd put the finishing touches on the roster here over the next seven or 10 days."
