I do understand the mentality Travis hitting ninth. He gets on base well and that's a good reason to have him hit first, but that might take 1 AB away from Jose, JD or EE and you want your best hitters to get as many AB as possible. Martin is on a tear so that's fine.
then you go to Travis 9th because there is a good chance he is on base when those top 3 come up without taking away one of their AB
