While the 2014 Prospect Guide has spray charts and isolated power for the position players in the Top 40, I do not include that information for the bonus prospects for space and time concerns (which in turn causes pricing issues and I want to keep the price as low as possible).  What I did do though was look at all of that information for all of the players as part of my process for evaluating them and I kept track of all of the data for all of the position players for use to look at today. There were 45 players of the 100 who were position players in the 2014 Prospect Guide, and I broke down switch hitters for each side of the plate, several players did not have enough plate appearances to warrant viewing the data as the sample simply isn’t large enough to make anything of. All players are listed at the bottom of the post in alphabetical order.

With this data there are several factors that need to be noted, particularly the park factors for each stadium as well as the league factors. I don’t have the league factors, but generally speaking this is how the various leagues break down:

Hitter friendly leagues: California League (Bakersfield), Pioneer League (Billings) and Arizona Rookie League (AZL Reds).

Neutral leagues: International League (Louisville), Southern League (Pensacola) and Midwest League (Dayton).

Now, simply being in a certain league doesn’t mean your park plays that way and some parks play very different to left field than to right field or to center field. So I am also going to include the park factors for the 2013 season. You can read more in depth about the park factors here.

Where you really want to pay attention to in the image above is the far right column and the bold numbers for how the home stadiums played and you can do some adjusting in your head based on those numbers.

Which players showed the best pull power in 2013?

The top player here was Jose Ortiz. The 19-year-old catching prospect absolutely crushed the ball when he pulled it to left field where his isolated power was 1.214. That means when he had a hit to left field, he averaged more than a double. That is flat out incredible. It is also worth noting that his home stadium hurt power to left field. For the players in full season ball, the top pull power hitter in 2013 was outfielder Kyle Waldrop. Waldrop had a slight edge over teammate Juan Duran with a .786 isolated power. Right field in Bakersfield was slightly friendly versus the league, and the league overall does favor hitters.

Which players showed the least pull power in 2013?

It isn’t surprising that the top (or bottom depending on how you want to look at it) three players in this category are all switch hitters, but one of them stands out among them all. Tucker Barnhart had zero extra-base hits as a right hander to left field, giving him a .000 isolated power. Among those in rookie ball is another non-surprise, Alberti Chavez. The youngest player on the list who played his age 17 season, his isolated power was just .158 in 2013 to the pull side. The next closest from the rookie levels was .333 by Avain Rachal. The number for Chavez though does include his brief time spent in Bakersfield.

Which players showed the best power to center field in 2013?

The guy at the top of this list isn’t much of a surprise either. Juan Duran has the best raw power in the entire system and he spent his entire season playing in Bakersfield where it is just 354 feet to center field. Duran posted a .533 isolated power for the 2013 season. Among those in full season leagues, the top 5 players all spent roughly half of their season in Bakersfield or longer. The rookie level leader was once again Jose Ortiz, who posted an isolated power of .464 to center field. The Mustangs home park, Dehler Park, hurt power to center compared to the rest of the league.

Which players showed the least power to center field in 2013?

Another portion of the list and switch hitters find themselves at the top (or bottom) of this list. Henry Rodriguez and Sammy Diaz, both as lefties, tied with a .040 isolated power to center field. Rodriguez played in Louisville, which slightly hurt power to center. Diaz however spent most of his season in Dayton where center field actually boosted power quite a bit. At the rookie levels there were three players who went without an extra-base hit during their seasons to center field. New draftee Cory Thompson isn’t a huge surprise, but he found himself tied with Jonathan Reynoso and Gabriel Rosa, who has a lot of raw power and was among the top pull power hitters in the system during 2013. Reynoso finds himself among the leaders in opposite field power, so his power to center may just be a bit of an aberration. Rosa and Reynoso were hurt by the home park, while Thompson should have been helped out by his home park.

Which players showed the most opposite field power in 2013?

Yorman Rodriguez tops this list with a .421 isolated power and was the only full season player over .365 in this category. That isn’t much of a surprise as Rodriguez has above-average power potential and uses the opposite field more than just about anyone else in the system. Jesse Winker is the only other full season player over .320. On the rookie season side of things, Aristides Aquino separated himself from the rest of the group as he posted a .529 isolated power to the opposite field while Jonathan Reynoso was second with a .444 mark.

Which players showed the least opposite field power in 2013?

Among full season players, Ronald Bueno came out on top (or bottom) of this list. From the left side of the plate he didn’t have an opposite field extra-base hit. There were 12 players in full season ball that had an isolated power to the opposite field under .100 and 2 more who were exactly at .100. In rookie ball the youngest player with data finds himself at the top (or bottom) again as Alberti Chavez didn’t have an extra-base hit to the opposite field. The next guy on the list for the rookie ball players though is a big surprise: Phillip Ervin, who posted a .071 isolated power to the opposite field.

Which players showed the biggest gap between pull and opposite field power?

For the regular season players, Kyle Waldrop shows up at the top of the list with a .643 difference. He was atop the list in the pull power portion, so he had the largest gap to make up. With that said, he didn’t show much opposite field power in 2013. Among the rookie season guys Phillip Ervin tops the list. He was second in the pull power portion, so like Waldrop, he had a big gap to make up. But also like Waldrop he didn’t show much opposite field power.

Which players showed the smallest gap between pull and opposite field power?

There were only three players in the entire group, both full and rookie seasons who had more opposite field power than pull power. Tucker Barnhart as a right handed hitter was the only one from full season and he posted a .100 improvement, but he didn’t have an extra-base hit to the pull side so there was a built in advantage. On the rookie level side of things, Avain Rachal tops the list with a .096 improvement and unlike Barnhart from the right side, Rachal had extra-base hits to build upon.
