JUPITER, Fla. -- The Cardinals are nearly a week into Spring Training, and right-hander Carlos Martinez remains a no-show due to visa issues restricting him from leaving the Dominican Republic. General manager John Mozeliak said that the club has still not been given any indication on when to anticipate his arrival.

Martinez's absence has prohibited him from taking advantage of working alongside pitchers from the Cardinals' Major League roster. The Cardinals had invited the 21-year-old rising prospect to big league camp for that type of exposure.

However, with each day that passes, Martinez's window of time in Major League camp is shrinking. Though he is throwing while awaiting approval of his visa, he's now not on the same schedule as the Cardinals' pitchers who began workouts under coach supervision in Jupiter last week.

If the Cardinals determine that Martinez is too far behind, they could alter his assignment and send him immediately to Minor League camp. The organization has an early Minor League camp that begins on Saturday.

"The key is we don't want him to be injured," Mozeliak said when asked about potential scenarios for Martinez. "He's probably working out and stuff, but it's probably not the same as being here. We want to make sure that he can prepare for the season. Obviously, he was invited to Major League camp but can't get in."

After making seven high-A starts to begin the 2012 season, Martinez posted a 2.90 ERA in 15 Double-A appearances (14 starts). He was recently ranked by MLB.com as baseball's 33rd-best prospect heading into 2013.

Classic-bound Boggs to keep normal routine

JUPITER, Fla. -- Two weeks from Sunday, Mitchell Boggs plans to depart for Arizona, where he will begin preparing for the World Baseball Classic with his U.S. teammates.

The spring interruption prompted Boggs to begin throwing about two weeks earlier this offseason. His routine since, though, has been and will remain unchanged.

"For me, I would want to stay on whatever normal rotation I would have been on anyways," Boggs said. "I don't want to squeeze a bunch of games in here just to get them in. I don't want to try and force something this early. Right now, it's just getting all my pitches where I need to be before I get out there. That's a good place to be in without having to worry about arm strength and things like that. Now I'm just able to fine tune everything."

Boggs threw his first session of live batting practice on Saturday and will throw at least one more before making his first Grapefruit League appearance.

He also noted that if he approaches this spring like he has other camps in recent years, he should be ready for a competitive environment in March, when the three-week international tournament is held. That's because Boggs has typically reported to Spring Training competing for a Major League job.

Boggs said he has been in contact with Team USA pitching coach Greg Maddux since being named to the club's roster. The opportunity to work with one of his former idols is something also not lost on Boggs about this Classic opportunity.

"I can think back to when I was 12 years old and my favorite players were Greg Maddux, John Smoltz and Chipper Jones," said Boggs, a Georgia native. "I get to play for Maddux. I got to play with Smoltz. And I've gotten to play against Chipper. That's pretty neat."

Worth noting

• Manager Mike Matheny said he still hasn't determined whether he'll hold an intrasquad game before opening Grapefruit League play on Saturday. Rain cancelled the Cardinals' planned intrasquad game last year. This spring, Matheny already has fewer workout days in the schedule because of the World Baseball Classic.

"I'm going to wait and see what we look like and see how things are going," Matheny said. "I'll see what we've got accomplished. You always put a day in there to go that direction if you need it, and sometimes it's to break up the monotony more than anything else. But [Saturday] is not that far away and we have a lot left to accomplish, so I'm not sure we will."

• Matheny said the Cardinals have made plans to schedule at least one 'B' game against the Marlins this spring. This will give the club an additional opportunity to find playing time for players in Major League camp. The Cardinals and Marlins share a Spring Training complex in Jupiter, Fla.

• Just days after the heat index hit 90 degrees, the Cardinals began workouts on Sunday in sub-50 degree temperatures. The workout schedule did not last as long as it did on Saturday, but players and staff participated in an autograph signing afterward.
