It wasn't a Cactus League Extended Spring Training game, but the Cubs did play an intrasquad game this morning on Field #6 at Mesa CubTown at Riverview Park.
Some of you may notice that when there is an EXST intrasquad game or a Cactus League EXST split squad doubleheader, that (with the exception of the pitchers and catchers, who move back & forth between the squads) one squad (Squad "A") is essentially the proto-Euguene Emeralds, and the other one (Squad "B") is essentially the proto-AZL Cubs. The squad rosters change slightly every now & then, but what you see now is probably pretty close to what will likely be the case next month when the two teams are officialy separated.
