Myworld’s Top Southern League Prospects

Last week myworld took a look at the Pacific Coast League and had trouble finding pitchers we liked. This week we took a look at the Southern League and found plenty of pitchers to include in our top ten. Again, the prospects are selected based on the numbers they have put up this year. If they do not have good numbers they do not appear on this list.

1. Michael Kopech RHP (White Sox) - The first round pick of the Red Sox in 2014 is one of the hardest throwers in baseball. He was one of the headline players the Red Sox shipped to the White Sox for Chris Sale. As a starting pitcher his fastball can hit triple digits, but it will sit in the 95-97 range. His slider and change need to be enhanced to achieve success in the major leagues, but if not his velocity will allow him to survive in the bullpen as a closer. There were off field incidents last year that make some question his character but he appears to be pretty behaved this year. Command has been a problem with more than one walk every two innings. A .191 opposition average and 126 whiffs in just 98 innings of work make him an ace in process, if he can avoid injury, improve his secondary pitches and find the strike zone a little bit more.

2. Ronald Acuna OF (Braves) - The Braves have been aggressive with the promotions of the Venezuelan native. Every level he has played at he has found success. Ronald was signed out of Venezuela in 2014 for just $100,000 and his speed and power mix now finds him knocking on the major league door at AAA. Many compare him to Andrew Jones. Ronald started his year in the High A Florida State League and is currently playing in AAA. During that time he has combined for a .305 average with 15 homeruns and 35 stolen bases. His OPS has never fallen below .814 at all three levels. Expect a September promotion before the season is done.

3. Mike Soroka RHP (Braves) - The Braves drafted the Canadian in the first round of the 2015 draft. He is not the kind of pitcher who will light your eyes up with his velocity. He works around the plate with a low 90s fastball, curveball and changeup to achieve soft barrel on the ball contact. Last year he pitched at Low A. The Braves decided to skip him past High A and put him in AA. In 19 starts he has a 2.32 ERA, a .224 opposition average and 97 whiffs in 112 innings. His walk to whiff ratio is greater than 4 to 1. At 19 years of age he is one of the younger pitchers in AA. Expect his major league debut to be some time next year.

4. Luis Castillo RHP (Reds) - Castillo was originally signed by the Marlins in 2011. For some reason they were very intent on trading him, first dealing him to the Padres until an injury to one of the players (Colin Rea) the Marlins acquired brought Castillo back to the Marlins. The Marlins then found a taker in the Reds to acquire Dan Straily. Castillo, with his triple digit fastball that sits in the high 90s has the potential to be a much better pitcher than Straily. But the Marlins thought they were playing for now. Castillo also has a slider and change for his secondary pitches. Castillo had a nice 14 starts (2.58 ERA) though you would expect more whiffs (81 K’s in 80 innings) based on his fastball. The success has resulted in a promotion to the Reds. There he has held his own (4.05 ERA) but giving up too many long balls in the small park (7).

5. Kolby Allard LHP (Braves) - Kolby was the Braves first round pick in 2015 who dropped in the draft because of a back injury that limited his high school season. Last year he was able to start 16 games, rising to Low A for 11 starts. His fastball sits in the low 90s, plenty of heat for a left handed pitcher with an excellent curveball. His change is a third pitch. Like Mike Soroka the Braves skipped him past A ball and put him in AA where at 19 he is nine days younger than Soroka. In twenty starts he has not had as much success with a 3.75 ERA, a .268 opposition average and 86 whiffs in 105 innings. Expect the Braves to be patient with him and keep him at AA.

6. Brian Anderson 3B (Marlins) - A third round pick in 2014 myworld was impressed with what we saw of him in the spring. He had power to the gaps, played solid defense and carried a couple balls over the fence. Drafted out of college the Marlins can be aggressive with his promotion. With Martin Prado missing the remainder of the season this may be a good opportunity for Anderson to make his major league debut. In AA he slugged 14 homeruns with a .251 average leading to a promotion to AAA. In 12 games at AAA Brian is hitting .349 with three homeruns. Between the two levels his OPS is .816.

7. Tyler Mahle RHP (Reds) - Players drafted in the seventh round, as Tyler was drafted in 2013, are not considered the best prospects. Tyler had height (6′4″) and a skinny frame to fill. Once he matured his fastball went from low 90s to mid 90s. Tyler threw a no hitter last year and a complete game no hitter this year. In the Southern League he dominated the hitters with a 1.59 ERA and a .190 opposition average. A promotion to AAA has not led to the same success (2.88 ERA) but enough so that he should see a September callup this year if not sooner.

8. Nick Gordon SS (Twins) - The half brother of Dee Gordon was drafted in the first round in 2014. Unlike his half brother he may have the tools to stick at short. The power is a little short but the speed is there for him to be an impact player on the bases. Like Dee he would move to second if the Twins felt shortstop was a bit too much of a challenge for him. Nick is hitting .292 but showing a little more pop with a career high seven homeruns. He does not steal as frequently as his brother and the strikeout numbers need to be reduced, but a .362 OBA is good enough to fill the lead off role. The Twins have played Nick a little bit at second this year, but they have a bigger need at short. Expect him to make his debut there next year.

9. Luis Ortiz RHP (Brewers) - Luis was a first round pick of the Rangers in 2014. The Rangers traded him to the Brewers in the Jonathan Lucroy trade. His claim to fame was winning the MVP award at the 18 and under World Cup in 2014. As he has gotten older the weight has gotten greater and he will have to watch that. His fastball sits in the mid-90s with a slider and change as his secondary pitches. He still needs a lot of work on the change to make it an effective third pitch. He is repeating AA where he has limited the opposition to a .207 average. Injuries have been the biggest impediment to his advancement to date.

10. Luiz Gohara RHP (Braves) - The Mariners originally signed Luiz out of Brazil in 2012. Just before spring training this year they traded him to the Braves in the Mallex Smith deal. At 6′3″, 210 Luiz is a big boy with triple digit velocity to his fastball. The challenge has always been finding the plate. His secondary pitches (slider and change) were also below average so it appeared he would be destined for the bullpen. The Braves kept him in the rotation and he won a promotion to AA from High A and just recently his success at AA has led to a promotion to AAA. His combined opposition average at the two levels is .228 with 99 whiffs in 88 innings. He may still end up in the bullpen with the surplus of starters the Braves have, but with the success he is having the Braves will keep him in the rotation.

Other Prospects to Like

Mauricio Dubon SS (Brewers) - Originally signed by the Red Sox after drafting the Honduran born Dubon in the 26th round of the 2013 draft. He was made part of the Travis Shaw trade to acquire Tyler Thornburg, which could turn into a disaster if Dubon pans out. Dubon lacks power and is probably a bit short on the tools to play shortstop full time. But he appears to have the ability to hit for average and steal bases. Coming into this season he has a .306 minor league average. He hit .276 at AA with 31 stolen bases to earn a promotion to AAA where he is hitting .300 with six stolen bases. The Brewers have been rotating him between second and short. He could end up being a solid utility player.

Jen-Ho Tseng RHP (Cubs) - The Cubs signed Tseng out of Taiwan for $1.6 million in 2013. With a fastball in the low 90s he is not overpowering and at 6′1″ he will not intimidate hitters. His numbers up until this year have not been good. In 15 starts at AA this year he finished with a 2.99 ERA with more whiffs per innings pitched than in previous years (83 whiffs in 90 innings). His opposition average is at .232 when last year at AA it was .308. This success earned him a promotion to AAA where his success has continued with a 1.42 ERA and a .204 opposition average.

Fernando Romero RHP (Twins) - Romero was signed out of the Dominican Republic way back in 2011. He missed the 2015 season because of Tommy John surgery. Despite his 6′0″ height he still gets the ball to the plate in the mid-90s. In his first season at AA Fernando has been good with a 2.64 ERA in 19 starts and 112 whiffs in 105 innings. He has held the opposition to a .231 average. At 105 innings pitched he has reached his career high so expect him to stay in AA with the Twins watching his work load, especially after the Tommy John surgery. If he continues to see success expect him to make his major league debut next year, though the Twins could promote him for the bullpen this year if they want to limit his innings.

Stephen Gonsalves LHP (Twins) - The fourth round 2013 pick is not overpowering, but he can hit the mid-90s, but generally sits in the low 90s. A plus change is what leads to his success. In 13 starts he has a 2.47 ERA with a .206 opposition average. Despite his lack of heat he still strikes out more than a hitter an inning, the changeup making that heater look that much better. An injury resulted in a late start to the season but after his success in AA last year Gonsalves earns at least a promotion to AAA.
