pick, let me see if I interpret this correctly....(a) no duplicate years (range = 1950-2017), (b) years can be non consecutive, and (c) no duplicate franchises.
BTW, W-L records for pitchers at the MLB level are a relatively minor factor and depend more on offensive run support (or lack thereof) and defensive performance. I'll give it a go but I'd REALLY like it with a DH...vm
