My original post was not attempting to point out an illegal assignment. The assignment is legal. It is completely legal to the contract. That's what makes it a bad assignment. They wanted to have a ready reserve pilot in tonight. I was next for callout in line of contractual seniority (RR is a 1 day assignment, I was the junior reserve with 1 day of availability), except they had to give me 12 hour call out because I got stuck on L2 today. So that meant that I could not come in and sit until 2100 (after all of the flights leave.....Saturday only has 1/2 of the nightly "superpush").
What my original intent was to point out that this illogical assignment isn't a result of crew scheduling, it is a result of our wonderful contract.

Someone earlier commented that LC reserves should only get assignments that are 9+ hours out and SC get anything within that time frame. I completely agree. But language in the contract and schedulers manual says do not take window into account. If it is 0600 and there is a 2 day trip that reports at 1630, and there is a junior A5 reserve and a senior L1 reserve, both with 2 days of availability, common sense would state that the L1 pilot should get used and to save the A5 for something that might come up later in the day, but the contract prohibits that from happening.
