Grichuk has the skill set to become the everyday left fielder. Fowler’s arrival relieves the pressure of defending center field. The exiling of Matt Holliday, Brandon Moss and Jeremy Hazelbaker creates an opportunity for regular work.

Mozeliak cleared some roster clutter to ensure him playing time. If Grichuk can consistently produce as he did in September — hitting .269 with eight doubles, seven homers and 16 RBIs — he could mature into a valuable asset.

The Cardinals must also see if Wong can finally become the everyday second baseman. Mozeliak has conveyed this message to manager Mike Matheny over and over again, so there could be no misunderstanding.

Wong hit .262 in 2015 with 28 doubles, 11 homers, 15 stolen bases and 61 RBIs. Other teams, notably the Los Angeles Angels of Anaheim, Orange County, Calif., showed interest in acquiring Wong for his combination of speed, power and fielding range.

At 26, he is still tinkering with his swing. He needs to let pitches get deeper and use the whole field. He needs to bunt for hits. Wong wants to be a big-time player, but sometimes he wants it too much. Let him play and see if he finally settles in.
