Redmond, Marlins to get early sense of replay

JUPITER, Fla. -- Grapefruit League games will take on added significance this year, as organizations will use them as trial runs for expanded instant replay.

Select games this spring will be equipped for replay, but even in games for which the equipment isn't available, the Marlins will monitor plays that potentially could be reviewed.

Miami's video coaching coordinator, Cullen McRae, will have access to the telecasts, and the video room will play a major role in the process.

Replay details haven't been finalized, but each team will have no more than two challenges. Each team opens the game with one. If a review is requested and a call is reversed, the team gets a second challenge. If the initial challenge is lost, then the team will have no more challenges for the game.

From the seventh inning on, however, the umpires can decide if a play should be reviewed.

There will be a room at Marlins Park not far from the playing field where the umpires will go to get the ruling.

"We will have a couple of [spring] games where the system is here where we can use it," manager Mike Redmond said. "All of our televised games we will go through like we would in a regular game, and if there is a close play, we'll talk to Cullen, and he will relay whether we review it or not. We'll try to simulate to the best of our ability to prepare for it."

Strategy promises to come into play in regard to when a team should issue a challenge. Will teams use their challenges early, or hold off in anticipation of a potentially more telling play later in the game?

Getting the calls right, naturally, is the main objective, but Redmond is worried about the pace of the game.

"Pace of play is still a huge issue," he said. "They'll have the video within 10 seconds of the play. There's going to be a person in the camera well that is going to have a headset, and as soon as they get on the headset, they'll tell them if he's safe and out."

Yelich poised to produce for Marlins

JUPITER, Fla. -- One day of batting practice isn't going to be the answer, but it's definitely a starting point.

Left fielder Christian Yelich, 22, certainly sees it that way. He also sees an improved roster and the potential to substantially increase run production.

One of the game's top prospects at the beginning of Spring Training 2013, the left-handed-hitting Yelich broke in with the Marlins in late July. In 62 big league games, he batted .288 with a .370 on-base percentage.

Manager Mike Redmond plans to bat Yelich second, behind Rafael Furcal and in front of Giancarlo Stanton.

Like many position players, Yelich was in Jupiter days before full-squad workouts began on Thursday. And if Thursday is any indication, Yelich is primed to be the type of hitter that made him a first-round pick in 2010, lacing line drives all over the field on the first day of drills.

"We've been out there the past few days, but ... it's good to get the first one under your belt," Yelich said.

Yelich has added about 10 pounds since last spring and is now listed at 6-foot-4 and 200 pounds.

Though the Marlins brought in several free-agent position players to help boost an offense that ranked last in the Majors in runs scored and home runs a year ago, they will be banking on their returning players to progress in order for more runs to cross the plate.

"We're definitely going to be better," Yelich said. "We're going to be good. Any way we can help out our pitchers, we've got to do, because those guys keep us in the game every night. We know, as an offense, if we can give those guys some help, good things are going to happen for us."

Marlins meet with inspiring young journalist

JUPITER, Fla. -- By midmorning on Friday, a handful of players had lined up for sit-down interviews with a guest journalist at camp.

Malcolm Harris-Gowdie, 24, from nearby Port St. Lucie, has autism and cerebral palsy. He is an aspiring sports television broadcaster who was in town to raise autism awareness.

Steve Cishek, Jeff Baker, Mike Dunn and Giancarlo Stanton were among those who sat for interviews, which aired on CBS 12 in West Palm Beach.

One of the messages Harris-Gowdie delivers is that anyone can live their dreams.

"No limits, whatsoever," Harris-Gowdie said. "I want to be a sportscaster. This has been my passion ever since I was a kid, to be in front of the microphone. I know every single statistic in sports."

The questions the players were asked were light and fun.

"I want to ask the players: What advice would you give kids if they wanted to play in the Majors?" he said. "If they weren't playing baseball, what sport would they play? What was your 'welcome' moment to the Majors? Who was your favorite baseball player growing up and why? And your favorite team?"

Worth noting

• Closer Cishek threw off the mound for eight minutes on Friday and is easing back into full workouts. For the past few days, Cishek has been dealing with a stiff neck, which caused him to miss two bullpen sessions. He had hoped to play catch on Thursday, but the session was pushed back a day.

• Infielder Juan Diaz officially joined the team on Friday, one day after the first full-squad workout, after being delayed by a visa issue. Two relievers -- Henry Rodriguez and Jesus Sanchez -- have yet to report due to their own visa holdups, and there is no definitive time set for their arrival.

• The Marlins open their exhibition schedule against the University of Miami on Wednesday. The starting pitcher is expected to be named perhaps as early as Saturday.

• With 36 pitchers on the roster, the Marlins are looking to get enough innings for all, so they have arranged a "B" game against the Mets on March 10. They hope to play another such game in March.
