HOF Mike Mussina Captain boost can’t get to Tier 3.

Am I missing something? I set up a line up with all HOF pitchers , there are 6 starting pitchers of which u can only start 4 because you need one slot for the Mussina captain card. And there are only 2 HOF relievers (Rivera & Gossage). So that’s 6 & since Mussina counts as one , that’s makes 7 (which is only tier 1) then I added Babe to my regular line up and since he’s a pitcher it got me to tier 2 which is 8/8. But to get to the Tier 3 boost you need 10 HOF pitchers. Am I missing something???
