Catcher Matt Wieters, shelved since leaving the Orioles' March 12 game after just one inning with stiffness in his surgically repaired right elbow, resumed throwing Sunday.
Wieters completed a 25-throw session, gradually extending his distance to 60 feet. Provided he recovers well during today's day off, Wieters will throw again Tuesday.
"I was pretty encouraged with Matt today," manager Buck Showalter said. "We'll see how he feels tomorrow. He threw with a lot of intensity with it."
Wieters also took live batting practice for the second straight day. Showalter said Wieters was planning to get some at-bats Tuesday in a minor league game at the Twin Lakes Park complex in Sarasota.
When he does start getting plate appearances in games again, he likely will continue to log at-bats in minor league camp so that the Orioles could backdate any disabled-list stint to Friday, the first day players officially can be placed on the DL. If a player plays in a Grapefruit League game after Friday, DL stints can be backdated only until then.
Wieters, who had Tommy John surgery in 2014, hasn't played since he was removed from the March 12 game after one inning following a wild throw to second base on a stolen-base attempt.
Mistakes costly for Tillman: Right-hander Chris Tillman rued a pair of mistakes that the Tampa Bay Rays hit out of Ed Smith Stadium, but otherwise felt great about his longest spring training outing of the season Sunday.
"It was good," Tillman said. "I made a lot of good pitches last start and made a lot of good pitches this start. It's the mistakes I've got to cut down on. I made a couple today, but I'm looking at the positives. I made a lot of good pitches with all my pitches, and it's exciting."
Tillman's Grapefruit League slate got off to a late start because of a hip injury that delayed his debut until March 10. After two innings in a "B" game and 1 2/3 innings on Tuesday at Toronto, he completed four innings Sunday, striking out five batters and allowing three runs on five hits, including two home runs.
Around the horn: The Orioles made two roster cuts after Sunday's game, assigning left-handed reliever Jeff Beliveau and outfielder Alfredo Marte to minor league camp. Beliveau, who hasn't pitched in a game since labrum surgery in April, will get his first spring action today in a minor league game. Marte hit .280 this spring, going 7-for-25, with one homer and four RBIs. … Adam Jones and J.J. Hardy are slated to play in their first road game this spring Tuesday, when the Orioles face the Minnesota Twins in Fort Myers. … Chris Davis, Hyun Soo Kim, Pedro Alvarez and Wieters are scheduled to get at-bats in a minor league game Tuesday. … Left-hander Brian Matusz (right lower-back strain) made his first Grapefruit League appearance since March 2 on Sunday, pitching a perfect ninth inning. "It's a start," Showalter said. "His command, he's feeling for it a little bit right now, but I think it'll be good for him to get this one under his belt and feel a little better each time out. I saw him peeking at the [radar] gun a little bit." … Showalter said center fielder Xavier Avery has made significant progress in his recovery from a hip flexor strain that has kept him out since Friday.
