1. They haven't picked a replacement yet. The manager's due to step down next month, but so far, no one has stepped up to the plate.
2. You need to get as much experience now; so if someone leaves, you'll be ready to step up to the plate.
3. We weren't sure if Sue could do the job, but she really stepped up to the plate.
4. He's so motivated; he's the kind of guy who would step up to the plate whenever they need him.
5. Tim did alright as a project leader, but when things got tough, I don't think he really stepped up to the plate. He could have done better.
Stepping up to the plate means coming forward and assuming leadership or facing a challenge and meeting expectations.
