Astros shortstop Carlos Correa spent nearly all of Friday on the field at Osceola County Stadium doing a photo shoot for a commercial for Adidas — the sports apparel company with which he recently signed a mega-endorsement deal.

The monotony of infield drills would be unbreakable during Spring Training’s early days, if not for the chatter piercing the air: David Wright whistling at a teammate’s crisp double-play turn, then clapping another on the back, then poking fun at a reporter. Wright grinning, chuckling, happy simply to be here.

The heir apparent.

The Angels’ decision to not chase one of the premier free-agent bats they desperately needed did not stem from a refusal to exceed the $189 million luxury-tax threshold, owner Arte Moreno reiterated on Friday.

For Zack Greinke, it was just a normal bullpen session, his first official one of the spring, but it was evident by the crowd of front-office personnel and the burgeoning media contingent that locally, it was big news.

Former Angels general manager Jerry Dipoto, who now holds the same job with the division-rival Mariners, admitted in an interview with MLB Network Radio that “there were times where it was very difficult to do the job that I was asked to do because I was caught in between perhaps two different dynamics” while in Anaheim.

Perhaps the most anticipated player to arrive at Nationals camp was Jonathan Papelbon, back with the team for the first time since a dugout incident on Sept. 27 in which he grabbed teammate Bryce Harper by the neck.

Oakland is awakening.

The Red Sox are heartened by the addition of ace David Price. However, fans and media have expressed skepticism over whether the rotation is good enough after the big lefty. Red Sox president of baseball operations Dave Dombrowski and manager John Farrell did their best to quiet those concerns while speaking at Grapefruit League Media Day on Friday.

Tony Phillips is gone, both too soon and without the proper appreciation. Most of us never paused long enough to consider how well he played and his role in changing the game.

For the first time as a Yankee, CC Sabathia is showing up in camp without a guaranteed rotation spot. After bowing out on the eve of the American League Wild Card Game to seek treatment for alcoholism, the former ace says he feels great and is ready to compete for his job.

In his first meeting with the local media Friday, new Nationals manager Dusty Baker said the first order of business is to make sure the team is healthy. After all, 17 players went on the disabled list last year, mostly for lengthy periods.

Over the past half-decade, the Mets have assembled perhaps the best starting rotation in baseball. Their current dilemma is how to keep the entire group healthy.

After spending the past week acclimating himself to a new culture and country, South Korean pitcher Seung Hwan Oh is now adapting to a Spring Training program that differs from the one he followed in Asia.

Well, it sure is something.

Cubs president of baseball operations Theo Epstein said Friday that he and team owner Tom Ricketts will likely have conversations this spring about a new contract, but emphasized it was not a concern at this point.
