It could be staged in the same town, with the entire baseball world focused there, or in a different city with available stadiums.

One benefit of that system would be that pitchers could throw more pitches without the restrictive pitch counts that they currently play under at the W.B.C. For now, pitchers are limited to 65 pitches in the first round, and 80 and 95 pitches in subsequent rounds. Relief pitchers cannot throw on three consecutive days, regardless of pitch counts, and anyone who throws at least 50 pitches in a game must rest for four days. If a pitcher throws 30 pitches, he must rest a day.

The W.B.C. began on March 6 this year for some teams. Girardi thinks the first round should begin a week later, allowing pitchers more time in spring training to build up arm strength. An extra week, he thinks, could translate into an additional five to 10 pitches and could spare managers from having to go to their bullpens too early, which in turn places strain on the relief pitchers.

He also noted that there are more elbow injuries that require Tommy John surgery in April than any other month, suggesting that those injuries are caused more often by arm strength problems early in the year than by fatigue at the end of it.

“I think they have a better chance of being hurt in March than they do in July,” he said, “when they’re really built up.”

Such issues intrigue Girardi, who is also well versed on the effects of scheduling regulations and game rules. He is always ready to share a few pointed thoughts on baseball’s rules updates, like those governing instant replay that were introduced earlier this spring.

This year, Yankees reliever Dellin Betances is pitching for the Dominican Republic, and its manager, Tony Pena, is also the Yankees’ first-base coach. Girardi lauded the communication between the W.B.C. managers, like Pena, who maintain contact with the players’ clubs during the tournament. He said he has spoken to Pena about Betances and has texted back and forth with Hensley Meulens, who is managing another Yankee, Didi Gregorius, for the Netherlands.
