A question that should be asked is who do you want to control for longer, The Jays will need one of Norris and Sanchez. The odd man out could give the Jays an extra year of control. The Jays need to manage both of their innings and if they both start the season with the club, both will be shutdown by September. May be best to start Estrada and Sanchez until Sanchez gets around 120 innings then move him to the pen, Can bring up Norris when the clock passes and move Estrada accordingly. Downside is Estrada will get lots of innings, but he's really the only option.
