The White Sox rebuilding puzzle is getting closer to completion.

Zack Collins is reportedly en route to the major leagues, according to a report from Miami talk-show host Andy Slater. That adds another one of the White Sox highly rated prospects to the growing list of them at the big league level as the franchise’s contention window looks set to open relatively soon.

Collins was the team’s first-round draft pick in 2016, selected with the No. 10 pick that year out of the University of Miami. Currently ranked as the No. 11 prospect in the farm system, he’s always been praised for his offensive abilities. Last season at Double-A Birmingham, he finished the year with a .382 on-base percentage and launched 15 homers, also winning the Home Run Derby at the Southern League All-Star Game.

In 48 games with Triple-A Charlotte this season, Collins owns a .258/.382/.497 slash line with nine homers, nine doubles, 38 RBIs and 35 walks.

Collins has been lauded as a big bat, but there have been questions about other parts of his game as he’s risen through the system. From the day he was drafted, there were questions about his defensive ability, leading to speculation that he might one day end up at a position besides catcher. He’s also racked up the strikeouts in the minors, with 396 of them in 322 games over his four minor league seasons.

But the White Sox haven’t wavered in their confidence that Collins can be a big league catcher, and it looks like that’s the position he’ll fill should the White Sox call him up before the start of next week’s Crosstown series with the Cubs. Welington Castillo was removed from Sunday’s loss to the New York Yankees with back tightness. The team said Castillo will be reevaluated on Monday. With this report of Collins’ promotion, it looks like Castillo could be headed to the injured list.

Another top prospect reaching the majors adds another tangible example of rebuilding progress. Fans have been clamoring for the promotions of Dylan Cease and Luis Robert all season long, and while Collins might be a little further down in the rankings than those two, this should still please fans who, even in a season filled with positives, want to see a more rapid advancement toward the rebuild’s ultimate goal.

Collins will perhaps benefit from a lack of pressure, what with James McCann in the midst of a potentially All-Star season as the White Sox primary catcher. The White Sox could perhaps continue to lean on McCann, allowing Collins to ease into the major leagues.

But just like Michael Kopech last August and Eloy Jimenez in March, Collins’ mere arrival is a step forward in this process, one that should please fans immensely.
