BALTIMORE -- Top pitching prospect Dylan Bundy, who felt some discomfort when throwing off flat ground on Monday, saw team orthopedist Dr. John Wilckens on Tuesday and is headed to Florida to be re-examined by Dr. James Andrews.
Manager Buck Showalter didn't divulge Wilcken's diagnosis, saying only that the club "is still in the process" and will wait until after the appointment with Andrews, who gave Bundy a PRP (platelet-rich plasma) injection on April 29.
The 20-year-old Bundy -- originally diagnosed with tightness in his right flexor mass -- had been progressing setback-free until Monday, when he felt the discomfort while throwing from 120 feet at the team's spring facility in Sarasota, Fla.
Showalter kept mum on whether the discomfort is in the same area as the original injury or if it's something new and/or more serious.
"I'm not going to handicap it," Showalter said. "Obviously, I know a little more, but there's some potential for some good things and some potential for some things we'll have to continue to work at."
The fourth overall pick in the 2011 First-Year Player Draft, Bundy was ranked the No. 2 prospect in baseball by MLB.com entering the season but has yet to throw a pitch in 2013. He was optioned to Double-A out of Spring Training and last threw off a regular mound in March. In 2012 he went 9-3 with a 2.08 ERA in 23 combined starts between Class A and Double-A before making his highly anticipated big league debut in September.
Chen ready to begin rehab assignment
BALTIMORE -- Left-hander Wei-Yin Chen was in the clubhouse on Tuesday afternoon, and he will throw a bullpen session on Wednesday before going out on a rehab assignment on Saturday.
Chen, who arrived along with interpreter Tim Lin, is recovering from a strained left oblique, an injury sustained on May 12; manager Buck Showalter said that it's possible he'll make just one rehab start.
It hasn't been determined where Chen will pitch, but the plan is for him to go five or six innings.
"I think it's just a test," Chen said through Lin. "Get the game feeling back and that's it.
"Right now I'm pitching like it's Spring Training. It's step by step. But if I feel really good [after the] next outing, I'll definitely come back really soon."
If Chen is given the green light after Saturday, he could make three starts before the All-Star break, but Showalter said that won't happen, as the team will give him extra rest between his first few outings.
Chen is 3-3 with a 3.04 ERA in eight starts this season.
Baltimore signs draftees Harvey, Hart
BALTIMORE -- On Tuesday the Orioles announced that they have agreed to terms with their first-round Draft picks from 2013, Hunter Harvey and Josh Hart. The club has now signed nine of its top 10 selections from this year's Draft and 18 of its top 20.
Both Harvey and Hart took in Monday's game at Camden Yards and were on hand on Tuesday to sign their contracts and kick off their professional careers. Each will start at Rookie League in Sarasota, Fla., and will likely play in the winter instructional league, general manager Dan Duquette said.
Harvey, an 18-year-old right-hander out of Bandys High School in Catawba, N.C., was selected with the 22nd overall pick. Hart, an outfielder from Parkview High School in Lilburn, Ga., was taken in the competitive balance round with the 37th overall pick.
"It's been exciting. A lot going on, but definitely one of the most exciting days of my life," Harvey said. "My brother told me the other day, 'Three years from now, you could be a junior in college or you could possibly be in the big leagues.' So I just want to start my professional career instead of going to school."
Harvey went 8-0 with 116 strikeouts in 11 games (eight starts) as a senior in 2013 after going 7-0 as a junior. He's the third consecutive right-hander taken by the Orioles in the first round, following Dylan Bundy and Kevin Gausman.
"He's got a very fast arm and, for an 18-year-old, advanced delivery mechanics. We think he has the potential to be a front-line starter down the road, and we're very happy to have him," scouting director Gary Rajsich said.
Hart batted .449/.560/.757 in 107 at-bats over 36 games in his senior season. He had 18 extra-base hits, 29 RBIs and 39 runs scored. He also stole 34 bases in 36 attempts. He led Parkview to state championships in 2011 and 2012.
"Josh is an exciting multitool player," Rajsich said. "We think he has the chance to hit at the top of the order. And when you can get a leadoff hitter with his kind of speed that can play center field, those guys are rare. They don't come around very often, so we're very excited to bring him into the organization."
Hart said during the news conference that he is "dying to meet" center fielder Adam Jones. Jones apparently heard about it, and left the clubhouse to meet Hart and Harvey before they even left the media room.
Orioles investing in Sarasota
BALTIMORE -- The Orioles announced on Tuesday, in conjunction with the Greater Sarasota Chamber of Commerce, the team's $150,000 investment in the Chamber's "Sarasota Tomorrow Next" initiative.
"Sarasota Tomorrow Next," a regional community and economic development initiative, is intended to build on the "Sarasota Tomorrow" program. The new initiative will focus on enhancing sports tourism and preparing youth for the future, according to David Rovine, vice president of Orioles-Sarasota.
"Since relocating our year-round Florida operation to Sarasota in 2010, we have expanded our efforts to improve this region's economy, create jobs and help families," Rovine said in a release. "The Greater Sarasota Chamber of Commerce has helped us grow roots in Sarasota, and we are pleased to support the 'Sarasota Tomorrow Next' initiative to better the region's business climate and economy."
• Second baseman Brian Roberts went 2-for-4 in a rehab outing for Triple-A Norfolk on Tuesday night, hitting leadoff for the Tides.
• Steve Johnson (strained left oblique) is progressing slowly.
"[He's] trying to get in shape, " manager Buck Showalter said. "It's been tough. He's battling some things. He's gotten progressively better, but it's a little slower than I hoped. It's been a challenge for him, conditioning, all year because of some of the things that have kept him from it. So I hope he's using that time. We'll see if he is using it."
