Opening Day has several insert sets. There are a couple that are super short-printed and I am not going for the Cubs cards in those. Putting SSPs in Opening Day seems to go against the set's concept, which is a simple kid-friendly set.
This card comes from the Opening Day subset, which has a card for each team. The Cubs picture is from their 2020 opener, in which they won 2-0.
This set features some outstanding opening day performances. Baez hit two homers to kick off the 2019 season. Billy hit a 10th inning walk-off homer against the Cardinals to give the Cubs a 1-0 win. Fergie outdueled Bob Gibson.
Here's the homer.

The mascot set returns and includes Clark.
