Ben Badler reviews the catchers in the AFL: Link

• Red Sox catcher Luis Exposito provides a big target behind the plate for his pitchers, and the 22-year-old looks even bigger than his listed height and weight of 6-foot-3, 210 pounds. He threw out just three of 21 basestealers in the AFL, but he generally receives solid marks for his defensive tools. Though he doesn't swing and miss excessively, scouts have some concerns about the length of his swing, and the scouting consensus is that he's likely a backup at the big league level, with the potential to work himself into a starting role.

"Exposito is extremely physical, extremely strong and he has a great arm" said Mesa manager Brandon Hyde, who managed the Marlins' Double- A Jacksonville affiliate this summer. "He could be a power bat that could be a good catch-and-throw guy behind the plate."

I'd just edit that post, but I'm not a mod anymore, so...

Here's a working link to that Badler piece

Player, Max, average
Richardson, 95.3, 92.97
Lentz, 94.8, 92.79
Bierd, 90.5, 87.52
Province, 90.3, 88.38

Project Prospect with home-to-first times from the AFL here. These times were taken from video they got, and thus are more accurate than they probably would be live. I think they have some very interesting results on the Sox' contingent:

Rk		Player	Grade	Ave.	Bats	No. 1	No. 2	No. 3
7		Jose Iglesias	70	4.10	R	4.1
17		Ryan Kalish	45	4.25	L	4.3	4.2
31		Casey Kelly	30	4.53	R	4.5	4.5	4.6

So Iglesias is apparently faster than we thought, whereas Kalish might be slower. I kept Kelly in there for shiggles, and apparently they don't have video of Exposito running, not like we really care.

Of course, obviously take these with a grain of salt.

Project Prospect refusing to let the AFL die: Batted Ball data

Kalish among the league leaders in LD%, highest K%, and highest GB%
Iglesias among the league leaders in lowest LD%, lowest K%, lowest BB%, and highest GB%

EDIT: I had their K rates backwards. Kalish was high, Iglesias low. Nice catch Yirmi
