Eric, I can speak to Martin in that he hasn't been piggybacking in quite the same way that Ruiz has, as he has some shorter outings in the relatively recent past. Salem has had a habit this season of stretching their starters out for as long as they're able to pitch successfully, and at times, his longer outings have been a product of his dominance. You are probably right that he is now bordering in on piggyback territory, but frankly, we like to be sure that's the case with guys before slapping that tag on them, as it's not worth the time spent editing the rosters page back and forth.

I like to use batters faced as a better analog for such a designation. If a pitcher is routinely going through the batting order close to two times (say 16 or so BF), then I think of him as a piggyback starter. If a lot of a pitcher's "long outings" are based on the fact he didn't allow many over the minimum, I like to wait a bit more to see if he has a stinker that goes 2.1 innings or something but still saw that many batters.
