Time of game...
Mets vs Marlins: 2:09 (7 pitchers used)
White Sox vs Astros: 2:40 (10 pitchers used)
Rockies vs Padres: 2:27 (7 pitchers used)
Diamondbacks vs Dodgers: 2:41 (8 pitchers used)
Guardians vs Mariners: 3:05 (10 pitchers used)
Except for the Guardians vs Mariners, none of the games were particularly high scoring.
It seems that through the 1st two days of games, the driving factor for game time is all the pitching changes.
Unreasonable to expect a 2 hour game average. But closer to 2:30 seems possible this season.
