Question, what makes the screwball a gimmick pitch. It's not like it's an eephus pitch that he throws once a game to get a key strikeout. If he's throwing it regularly, and it continues to work, is it still a gimmick? And if so, and it just works because few other guys throw it, should it keep working as he moves up to higher levels? Not too many guys can throw a curve ball like Rich Hill, a sinker like Brandon Webb, or a cutter like Mo' Rivera. Gimmick pitch or just a good out pitch? You be the judge.
Chad Bradford has turned a "gimmick delivery" in to a pretty nice little career.
Agreed. "Gimmick pitch" is usually baseball writer hyperbole.
I think the key characterization is the consistency and repeatability of the "gimmick" pitch. Dan Quisenberry was consistently great throwing a telegraphed, low-80s sinker that everyone in the ballpark knew was coming. It was great pitch because it was consistent. Billy Taylor, on the other hand, rode a career wave that ebbed and flowed with his changeup.
Regarding Guevara, specifically--I'm fairly confident that is his offspeed stuff will hold up at higher levels. The bigger question with him is his fastball, because he will most likely need it to be at least a decent pitch. Does his fastball lack movement? Much like Zito, I'm sure Guevara needs at least a decent offering to set up the out pitch.
I'm speculating that the fastball is probably what has kept him at AA, rightly or wrongly.
