Three Cubs who were in the minors eight weeks ago — and in A-ball less than two years ago — did their best Friday night to show the St. Louis Cardinals at least part of what’s coming to the Cubs-Cards rivalry.

Jorge Soler: 3-for-3 and two home runs. Javy Baez: a go-ahead double in the eighth inning. Arismendy Alcantara: a homer in the ninth to finish off a 7-2 victory.

“We’re just waiting for Bryant now,” Baez said.

That’s probably going to be a long wait, certainly longer than players in the clubhouse prefer to see presumptive Minor League Player of the Year Kris Bryant join the show.

General manager Jed Hoyer said again Friday that the front office hasn’t budged on its plan to keep Bryant (pro-ball-leading 42 homers) from a big-league promotion this year, even after the Class AAA season ends in a few days.

But that hasn’t stopped Baez — and Anthony Rizzo and Starlin Castro before him — from wishing out loud for a look at him this year.

“For sure,” said Baez. “Who knows? In baseball, nobody knows anything. It’s not up to us.”

If nothing else, Baez and Soler are setting a high bar for Bryant once he arrives. Both homered in their debuts. And with his two first-pitch homers Friday, Soler joined Baez among only three players since 1900 to have three homers in their first three career games (Joe Cunningham, 1954 Cardinals).
