Good morning on this waterlogged Friday.

Batter up!

Major League Baseball’s season opener is Sunday and for Yankees and Mets fans, all eyes are on the teams’ younger players.

The Yankees’ season will be defined by the team’s commitment to youth and to those who have come up through minor league teams, according to Billy Witz, who covers baseball for The New York Times.

“The Yankees have always been able to maintain a championship contender by opening their checkbook, signing the high-priced free agents that other teams couldn’t afford, and just collecting talent that way,” Mr. Witz told us.

“But in the last few years, that hasn’t worked very well. So they’re trying a new way of business, to maintain and develop young talent, which is cheaper and has worked very well for other teams.”

The Yankees’ first baseman Greg Bird and the catcher Gary Sanchez are two players to watch.

And the Mets have ”five or six pretty promising young pitchers,” Mr. Witz said, singling out Noah Syndergaard, Jacob deGrom and Matt Harvey as those to keep an eye on.

So how does all of this bode for the coming season?

The Mets are likely to get further than the Yankees, Mr. Witz predicted.

“Both teams have some pretty promising young players, but the Mets are more established,” he said, “a little bit older with a proven record in the league. So that lends their prospects a little more credibility.”

The Mets have also journeyed to the playoffs two years in a row, “so they clearly have visions for the World Series,” Mr. Witz said.

“The Yankees are probably not a playoff team this year because they’re unproven,” he added. “These players have proven themselves in the minor leagues to be very good, but that doesn’t always translate to success at the major league level.”

So this will be a chance for Yankee fans to see what the future might look like and how much promise — or false hope — there really is.

The Yankees play the Tampa Bay Rays at Tropicana Field on Sunday at 1:10 p.m., and the Mets host the Atlanta Braves at Citi Field on Monday at 1:10 p.m.

Happy 150th birthday, Prospect Park.

Brooklyn’s flagship park, completed in 1867, was imagined by Frederick Law Olmsted and Calvert Vaux, “the same minds which transformed that ‘howling wilderness’ of Manhattan Island to the most magnificent public garden in the world,” The Times wrote that year.

The construction of the park uncovered relics — like “mingled balls and bones” — from the Revolutionary War.

“The ground will be preserved as nearly as possible in its early shape, and distinctly marked for the veneration of future generations,” The Times reported.
