DateQuestionAnswer
2013-09-06 14:00:00 (link to chat)Is Keyvius Sampson the guy who dominated AA, or the guy who got killed in AAA (approx. 1/1 K/BB) both before and after his stint in AA?
(edwardarthur from Illinois)		Keyvius has one of the coolest names in the minors, so he has that going for him. He is both the guy who dominated AA and the one who struggled in AAA - Sampson has a powerful delivery that he struggles to repeat, and though he was able to ride his stuff in AA, it appears that AAA hitters waited him out. Looking at the game logs, he never walked more than 3 batters across 18 starts in AA, but he walked 4 or more in 4 of his 9 starts in AAA.

Sampson is an example of why pitchers with great momentum get a bad rap. It is more difficult to harness the higher levels of kinetic energy, but the key is finding each pitcher's ideal timing pattern. Right now he is too fast into foot strike, and his signature asks for a slightly slower delivery. Most pitchers are too slow, however, and though they can stabilize balance a bit easier, they also open up a larger window of time for the delivery to fall off-track. His solution lies somewhere in the middle.

2013-08-14 13:00:00 (link to chat)Higher ceiling: burch smith or keyvius sampson?
(Matt from San Diego )		I wrote up Smith very strong early in the season, when he was holding 92-96 mph and touching 98 and showing plus command. He's had trouble holding that same velo and staying on the mound since. So I'll go with Keyvius Sampson, although neither one is a surefire MLB starter. I'm really interested to see which Burch Smith shows up in spring training 2014 â€" the dominant early-season Smith of this year, or the MLB version that was sitting 89-92 mph by the third inning. (Jason Cole)
2013-08-22 13:00:00 (link to chat)David Holmberg or Keyvius Sampson for you ?
(Ernie from Houston)		Holmberg. (Paul Sporer)
2011-02-22 13:00:00 (link to chat)Hey Jason, I've never contributed a chat question, but I wanted to tell you I enjoy the podcast, especially when I listen with a Coca-Cola con azucar from my 30 refrigerator. As for baseball, I know you focus on the Rangers in ST, but I was wondering if you noticed anyone from another Arizona team, the Padres, who you really like as a prospect? Someone other than the obvious top-5 guys like Decker, Castro and the players obtained from the Red Sox.
(Padre from South America)		In AZ, I spend a lot of time watching the Rangers/Royals, but I also enjoy watching the Padres, DOdgers, Giants, and Mariners. I love watching Tate on the field. He's not pretty during game action, but he gives you a ton to dream on. Superstar level tools and about a .02% chance of full actualization. I think Jedd Gyorko is a player to watch just because of his name. Keyvius Sampson is another great name, but he also has a really good arm. (Jason Parks)
2011-01-03 14:00:00 (link to chat)Best bet to make big 2011 rankings jump... A - Keyvius Sampson, B - Luke Jackson, C - Taijuan Walker D - Madison Younginer
