Matt Cerrone, who is down in Florida reporting for Mets Blog and SNY, relays that El Duque is toying with his delivery. He is supposedly trying to lose the quintessential El Duque high leg kick, which is most likely causing some of his foot injuries.
From Cerrone:
...honestly, it’s impossible to tell if he looked good or bad…his delivery is a bit different…he was throwing sort-of sidearm at one point…Sidearm, you say? Well, he's always had a strange delivery, and him dropping to sidearm wouldn't surprise me.
To me, at least, throwing sidearm for me is much more comfortable and smoother, even if I'm only throwing a Wiffle ball. If Duque does stick with a sidearm technique, and can stay crafty, and more importantly healthy, he might keep his career somewhat on track.
