Dozens of free agents remain unsigned, including many household names. Trade talks that started back at the General Managers Meetings in November remain ripe to be revisited. Other conversations have only just begun. The next round of possibilities is only a text message away. As players take the field, there are questions to be answered, holes to be filled. Among the most intriguing of these fluid scenarios:

It’s spreading.

The Urban Youth Academy in New Orleans is still growing into its own. But in less than four years since opening, the facility has developed into an operation that serves thousands of kids in this baseball-rich community.

Adam Wainwright insists the moment wasn’t scripted, but it might as well have been so. There Wainwright was, the first out of the clubhouse door following the Cardinals’ morning meeting, the rest of the team’s pitchers and catchers trailing in line behind him.

Albert Pujols has been swinging the bat, but he will not be allowed to take part in aggressive defensive work by the time he reports to Angels camp next week. Pujols is basically 3 1/2 months into his recovery from early November surgery on his right foot, a procedure that was expected to keep him out of full baseball activities until early to mid-March.

Don’t tell Mike Aviles that Tigers position players aren’t officially due into camp until next week. The smile on his face as he took grounders on the workout infield at Tigertown suggests he’s having too much fun. His 5-year-old daughter Adriana’s battle with leukemia last summer might thankfully be over.

We’re so excited! We’re so excited! We’re so … so … scared …

Rangers outfielder Josh Hamilton is still experiencing discomfort in his left knee and will be examined by Dr. Keith Meister this weekend.

Though Giants photo archives weren’t immediately accessible Thursday, it’s safe to say that right-hander Johnny Cueto became the first player in franchise history to report to Spring Training with the tips of his dreadlocked hair dyed orange.

Nationals catcher Wilson Ramos is aware he is a free agent after the 2016 season, but that is the last thing on his mind. It’s about getting better on the field.

He’s the horse whisperer.

They don’t just grow on trees, after all.

It has already been a memorable start to the year for Masahiro Tanaka and his wife, Japanese television personality Mai Satoda, as they celebrated the arrival of a baby boy this week in New York. Tanaka returned to camp on Thursday as the Yankees’ pitchers and catchers officially reported to George M. Steinbrenner Field.

As part of his attempt to rebound in his second season with the Red Sox, third baseman Pablo Sandoval will resume switch hitting.

It’s the super look of the ’70s.

No concerns about that sweet Halladay jersey, though.

It’s pretty gross.
