Before Hellickson's last start, Shields worked with the rookie on his curveball, changing his grip. The results were evident as Hellickson turned in seven innings and allowed just two runs, while striking out seven Yankees on Tuesday.... "What I thought I saw [Tuesday] was better depth on the hook," manager Joe Maddon said.
Hellickson changed his grip so that he uses his middle finger to spin the baseball more than he used to on his curve. "We changed his grip up a little bit," Shields said. "He has got a really good curveball. I just think that he wasn't trusting it as much as he wanted to.
He put the time and the work in to be able to do what he did." Despite all of that, Hellickson still doesn't feel comfortable enough with the pitch to throw it early in the count. "I feel like it's a good pitch for me right now with two strikes," he said. "I'm still working on throwing it for [early] strikes."Those were Hellickson's comments after his first outing with the new grip. Let's look at how his curveball looks different since the work he put in with future pitching coach James Shields.
A lot of pitchers feel that you can get "tighter" rotation and sharper break on the knuckle/spike curveball. Also, many pitchers throw it with better velocity than their previous CB. From personal experience, I toy'ed with a spike CB my last yr of pro ball, but didnt "get it". I couldnt get a feel for it, and wasnt properly instructed how to throw it.
But earlier this yr when I was messing around over at Jesuit baseball practices, my friend and former MLB pitcher Geoff Goetz showed me the proper was to throw a CB. It DEFINITELY had sharper break than my traditional grip CB, and the velo was much better as well.
Maddon mentioned more depth. David mentioned sharper break. Pitch f/x also echoes those statements.

The average horizontal break on is curve has dropped from 9.8 to 8.4 but the change is more noticeable on his vertical movement as it has dropped to -8.36 this season while it was -3.2 last season. That has helped lead to some early season changes in his curveball outcomes compared to last season:
In a piece this past November about Hellickson's issues against left-handed hitters, I proposed the following conclusion:
Hellickson adding another pitch to use against lefties, whether it be tightening up his curveball or changing where he prefers to locate it, would help give Hellickson reduce his splits between righties and lefties.
The tightening of the pitch has already been demonstrated but notice how Hellickson has also changed the location of where he spots his curve this season. Compare 2011 (first image) to 2012 (second image):
In 2011, Hellickson's slash line was .230/.323/.403 against left-handed hitters in 416 plate appearances with 47 walks and just 39 strikeouts. This season, the slash line is not much different at .232/.299/.415, but he has 14 walks and 23 strikeouts in 159 plate appearances against lefties so far in 2012 compared to a .231/.279/.405 slash line against righties in 130 plate appearances.
In 2012, Hellickson's strikeout rate is up, his walk rate is down, and he continues to out-pitch his FIP just as he did last season. It is nice to see a second year pitcher coming off a successful rookie campaign be open to coaching and make the necessary adjustments to stay one step ahead of the hitters and the evolution of Hellickson's curveball has definitely been a part of what has allowed Hellickson to remain successful so far in 2012.
