Hollands 'in shock' after making 25-man roster

PHILADELPHIA -- Mario Hollands had one word to describe his reaction to being named to the Phillies' Opening Day roster: shocking.

Hollands, a left-handed pitcher who was one of the bright spots in Spring Training, will start the season in the big leagues after making nearly every stop in Philadelphia's farm system over the last four years.

The 25-year-old had an impressive spring, but that didn't stop Hollands from expecting the worst when he was called into manager Ryne Sandberg's office on Saturday afternoon at Citizens Bank Park.

"In the back of your mind, you're not expecting it, honestly," said Hollands, who joins an eight-man bullpen. "But it was a good shock. I'm still in shock a little bit."

The Phillies like Hollands' funky delivery, which Sandberg said "creates some ground balls," his effectiveness against both right-handed and left-handed batters and his ability to pitch multiple innings. They also think he can handle the big league stage after performing at a high level in the Venezuelan Winter League for Tiburones de La Guaira over the offseason.

"I think he benefited from playing in Venezuela this past winter," Phillies general manager Ruben Amaro Jr. said. "That's a high level of competition and a high level of stress there as well. When you start throwing in those situations and start having success in those areas, that's important."

Hollands said his experience in Venezuela prepared him for Major League camp.

"I think it helped confidence-wise, being able to compete against big leaguers and good players and good teams," Hollands said. "I carried that over into Spring Training."

Hollands still has a long road ahead to remain in the Majors, but he allowed himself a moment to reflect on years of hard work to get to this level.

"It's kind of rewarding, because I've been all over the place the last two years in the organization," Hollands said. "It feels good to know it paid off in the end, to at least make it this far and hopefully keep it going into the season."

Gwynn Jr. excited to tell father after making Phillies

PHILADELPHIA -- Tony Gwynn Jr. has an important phone call to make.

The outfielder is back in the big leagues for the first time since 2012 after making the Phillies' Opening Day roster on Saturday. He can't wait to share the good news with his father, Hall of Famer Tony Gwynn.

"He's always been supportive, so I look forward to breaking this news to him," Gwynn Jr. said.

It's been a long road back to the Majors for Gwynn Jr. He spent all of 2013 with Triple-A Albuquerque, the Dodgers' affiliate, after playing parts of seven seasons in the big leagues from '06-12. But the 31-year-old has found a home with the Phillies, who like him for his defense at all three outfield positions.

Gwynn Jr. couldn't stop smiling in the Phillies' clubhouse at Citizens Bank Park after learning he was back in the show.

"Nothing can replace the big-league feeling," Gwynn Jr. said. "As many times as I've been called into an office and been told I made the ballclub, the feeling doesn't change. It's always something that's really hard to explain, the excitement once they tell you you're part of the ballclub."

His father will certainly be excited, too.
