The Houston Astros didn't have to make a big move this summer, with a 12-game lead in the loss column in the AL West as of this morning. But with Dallas Keuchel struggling a little bit post-injury and Lance McCullers Jr. on the disabled list again, they have had enough rotation questions that acquiring a durable, front-line starter for the playoffs made sense. I don't know if anyone expected them to do what they did, trading for Justin Verlander to join their rotation now and for the next two seasons. Given the uncertainty around every rotation member -- Keuchel, McCullers, Collin McHugh and Charlie Morton have all missed significant time in one or both of the past two seasons due to injury -- Verlander helps the team even if he's just an average starter but makes 30 starts a year.
