The Orioles reduced their camp roster to 46 (with nine non-roster invitees) by optioning injured right-hander Dylan Bundy to Class AA Bowie.

It was a procedural move, because Bundy needed to be placed on the minor league disabled list by Friday.

“It just changes where I am going to be,” Bundy said. “I’m going to be working with [minor league medical coordinator Dave Walker] down there [at the minor league complex] and that’s who I’ve been working with the first six months of my rehab. So we have a good relationship. It will be fine.”

Bundy, 21, had elbow ligament surgery in June and has been rehabbing in Sarasota since. Since the opening of camp he has been with the big league club, working with the major league athletic trainers and further bonding with the players.

Bundy, the club’s top pick in 2011, is still considered the 2014 top prospect in the organization by Baseball America.

Chen logs four innings in tie

Wei-Yin Chen became the first Oriole to go four innings this spring and Henry Urrutia’s first homer helped contribute to a 2-2 tie with the Minnesota Twins in Fort Myers.

The Orioles took a 2-1 lead into the ninth, but reliever Troy Patton gave up a solo homer to former Orioles’ farmhand Brandon Waring. Because the Twins also had a split squad against Tampa in Port Charlotte on Friday, they didn’t have enough pitching to extend the game and the sides agreed to the tie.

Chen pitched well, allowing three hits, one walk and one run while striking out three and throwing 60 pitches in four innings. He’s now allowed three runs in nine innings this spring.

“Before the game, the goal for me was around 60 pitches, so I was pretty happy to get through four innings within the pitch limit,” Chen said through an interpreter.

Casilla scratched with injury

Infielder Alexi Casilla, who has been limited this spring to a right hamstring strain, was scratched from Friday’s lineup with a hyper-extended left knee. The Orioles weren’t immediately sure of the extent of the injury.

Casilla, a non-roster invitee who is battling to regain his utility infield spot, has played in just three games and is hitless in five at-bats.
