Just returned from a 10 day trip to Jupiter. As far as "hopeful new contributors", the most pleasant surprise to me is how Jose Martinez and Harrison Bader are hitting the ball. Nice to see a little power from those two.
Gyorko, Diaz, and Kelly have looked good hitting as well. Still waiting on Fowler to show a little presence at the plate.
As far as pitchers are concerned, I know that Sandy Alcantara is still a couple of years away from the big league, but this guy has the "it" factor. He is still very rough around the corners, but he has some juice on his pitches. Also, now that Sam Tuivailala has went back to his curve, I am expecting to see him in St. Louis on a regular basis this year. So far, Tuivailala has ten strikeouts in four innings.
Other news: Randal Grichuk has to be the most approachable and humble player I have ever seen in Spring Ball (like to see 30 HR this year out of him!) and it is very strange not see to see Matt Holiday with the team.
