Bundy pain-free, has full range of motion

TORONTO -- Dylan Bundy, the top-ranked pitching prospect in baseball by MLB.com, is experiencing no pain in his forearm/elbow area and has full range of motion roughly four weeks after receiving a platelet rich plasma injection to expedite the healing process for his right flexor mass tightness.

"That's two good combinations," manager Buck Showalter said.

While the latest news surrounding Bundy is positive, the 20-year-old is not in the clear yet. Bundy will have to be evaluated by renowned surgeon Dr. James Andrews one more time before he can take his rehab process a step further.

If everything checks out well on Andrews' end, Bundy could begin a throwing program after June 10, which would be the end date of the six weeks off he was given.

The right-hander, who has yet to appear in a game this season, made his Major League debut in September after going 9-3 with a 2.08 ERA in 23 starts between Class A and Double-A ball. Baltimore selected Bundy with the fourth overall pick in the 2011 First-Year Player Draft.

X-rays negative on Hunter's pitching hand

TORONTO -- Orioles reliever Tommy Hunter fielded a hard-hit ball from Toronto's Jose Bautista with his bare hand in the eighth inning of Sunday's 6-5 walk-off loss. He had an X-ray taken after the game that came back negative.

Hunter was tasked with facing Bautista with the bases loaded and the Orioles leading, 3-2. The hard-throwing righty peppered Bautista with three straight fastballs clocking at 98, 98, and 99 mph before Bautista drilled another 99-mph heater up the middle. Hunter's instincts kicked in and he reached out to field the scorcher with his throwing hand before jogging toward first base and tossing it to Chris Davis for the final out of the inning.

"It was crushed," said Hunter, who had his hand wrapped in a tensor bandage. "Sometimes you play a little shift on him, but on a ball up the middle. I just wasn't able to get my glove there fast enough."

Hunter was optimistic he wouldn't miss any time, but it's entirely too early to determine if that would be a reality. Manager Buck Showalter was already preparing for Hunter, who said he will be reevaluated Monday, to be out a couple days.

The 26-year-old Hunter said it felt exactly how it looked.

"It feels like it got hit by a baseball," Hunter said.

Blue Jays starter Chad Jenkins couldn't believe the play, and neither could many of Hunter's teammates, who were talking about it following the contest.

"If something is not broken, he might have the strongest hand ever," Jenkins said.

Hunter, who allowed one run on four hits over 1 1/3 innings, also worked out of a bases-loaded jam to end the seventh inning.

Wieters bats seventh, gets four hits

TORONTO -- Mired in a season-long slump, Orioles All-Star catcher Matt Wieters was dropped to the No. 7 spot in the batting order for Sunday's series finale against the Blue Jays, which is the lowest he has hit to start a game since June 30 of last year.

Perhaps that's all he needed to get going, though, as Wieters turned in his best offensive performance of the season in Baltimore's 6-5 walk-off loss at Rogers Centre.

Wieters went 4-for-5 with three doubles and three RBIs. It was the first time this season that he has tallied more than two hits in a game.

"I was just able to get some fastballs in the middle of the plate and get a barrel to them," Wieters said.

Wieters had a rough April, but he raised his batting average to a respectable .250 in May after his four-hit game. And, to his credit, 12 of his 19 hits during the month have gone for extra bases, but there remains some things the team is trying to iron out with him at the plate.

Orioles hitting coach Jim Presley said some mechanical hitches are preventing Wieters from consistently driving the ball.

"He's drifting a little bit from the left side, and he's getting out front and rolling over balls," Presley said. "We are trying to get him to stay behind the ball."

Wieters said one big game isn't enough for him to say he's on the verge of a turnaround. As a catcher, he's well aware that a pitcher can get hot and disrupt any sort of success or rhythm a batter is having at the plate.

"We're just going to take it one day at a time, and hopefully we can carry on some," Wieters said. "But each day is a different pitcher, different everything."

Although Wieters has struggled at the plate, the two-time American League Gold Glove Award winner has remained a force behind the dish. He has thrown out 56 percent (10-of-18) of attempted basestealers this season, which is more than double the league average. The 27-year-old ranks second in the Majors in caught-stealing percentage.

Worth noting

• Right-hander Jake Arrieta, who was optioned to Triple-A Norfolk on Thursday to make room for rookie Kevin Gausman on the 25-man roster, made his first appearance for the Tides on Saturday. Arrieta logged one inning of work, allowing two runs -- one earned -- while walking a pair and striking out one.
