By far not every minor league roster has been revealed but on several websites of minor league clubs you can see the name of players that has been placed their by the Major League parent club.
Here is provisional overview. Not everything is clear yet, so updates will follow.
Chadwick Tromp: The 21-year old Aruban catcher has been placed on the roster of the AAA Louisville Bats (Cincinnati Reds). Last season Tromp played at A full season level with the Dayton Dragons but late in the season he was promoted to AAA Louisville. With the Bats he did do a nice job as he collected two hits out of four at bats in the sole game that he played vs the Toledo Mud Hens. On the defensive side, he did not commit an error in this game but allowed one stolen base nevertheless.
Juremy Profar: The younger brother of Jurickson, struggled at bat at times when he played at A Full Season level with the Hickory Crawdads (Texas Rangers). Nevertheless the Rangers have placed him on the roster of the High Desert Mavericks (A Advanced, California League). At A Full Season, Juremi hit a modest .200 in the final ten games of the season. Eventually he finsihed the season with the Crawdads with a .272 average. With the Mavericks, Juremi hit .240. Perhaps that the dry desert air will help him to get more basehits.
It remains to be seen where the Mavs will play this season as they have been locked out of their stadium by the city of Adelanto as the two parties disagree on the amount of the stadium lease.
Danny Arribas: Danny Arribas has been placed on the roster of the West Virginia Black Bears (Pittsburgh Pirates affiliate) so far. But the season of that team will only start in June , so it may very well be that the third baseman will move up on the minor league ladder before the start of the New York -Penn League season. Last year Danny also played with the Black Bears as he ended the season with a decent .282 batting average. On the defensive side there is room for improvement. Danny committed seven errors at third base in just twenty games. He also played thirteen games as a catcher, but this year his is on the roster as a third baseman solely.
Jiandido Tromp: Jiandido starts the season where he ended the previous one: with the Lakewood BlueClaws (Phillies). At A Full Season level, Jiandido struggled at the plate as he only got a .216 batting average. In the outfield he did a decent job with a fielding percentage of .992. In 108 games he committed ten errors.
Ademar Rifaela: This 21-year old outfielder from Curacao also starts the season where he ended the previous one. Rifaela will play for the Delmarva Shorebirds (Orioles) in the South Atlantic League. Last year he had a decent year at bat as he finished the season with a .262 average. On the defensive side he did a very good job as he only committed two errors in 59 games at A Full Season level.
Randolph Oduber: Randolph will start the season with the Harrisburg Senators at AA level. Last year his season was cut short as he was bothered by a nagging injury. He only played seven games in April before ending up at the DL. Apparently his injury already bothered him while playing as he only hit .188.
Spencer Kieboom: One thing is sure, Spencer Kieboom and Randolph Oduber will be team mates this year. Spencer was promoted to AA after a good Spring Training at MLB camp. Last season his batting average was so so (.248), but that is what you see quite often with catchers. Most of the time they are not very good at bat. Their main role is to guide the pitching staff through the game. And that is something that Spencer does very well. Last season he did commit only five errors in 69 games and threw out fourty percent of the base stealers.
Gianfranco Wawoe will also start the season where he played last year; with the Clinton Lumberkings (Mariners). Gianfranco had a cup of tea at AA with the Jackson Generals, where he played four games and hit .333, but was sent down to Clinton nevertheless. With the Lumberkings he hit .263 and committed ten errors in 22 games at shortstop. He also played a considerable number of games in the outfield where he played flawless.
Sicnarf Loopstok will start the season at A Advanced level with the Lynchburg HillCats (Cleveland Indians). Sicnarf started the season at A Short, but after only five games he was moved up to A Full season. But he played the most games by far at A Advanced level. The catcher from Aruba struggled at bat at that level with an average of .218. He committed three errors in 25 games behind the plate and threw out almost fourty percent of the base stealers.
It won’t come as a surprise that Aruban catcher Shawn Zarraga will start the season at AAA with the Oklahoma City Dodgers. At MLB Spring Training camp, Shawn had a solid time at bat as he was used mainly as an DH. He hardly got playing time behind the plate, so you knew in advance that he would not make the MLB roster.
Last year he appeared in only 18 games for the OKC Dodgers but he hit a ver respectable .303. Behind the plate, his defense is very good, but he lacks a good throwing arm as he only threw out 16 % of the base stealers.
Despite having a good season at A full Season, Darren Seferina will start the season with th e Peoria Chiefs again. Even though he spent all season with the club last year, the Cardinals apparently think that Darren should start at the same level. He hit .295 but committed thirtin errors (.971 fielding percentage), so perhaps that is the reason why he will start the season in Peoria.
Roger Bernadina will start the season at AAA with the Las Vegas 51s (New York Mets).
With the Albuquerque Isotopes, Roger had a decent season at the plate (.276) as he was named power hitter of the year by his team. He was invited to the MLB Spring Training camp by the Mets and after some visa issues, he reported a bit later at ST camp. During his time with the MLB squad, Roger got five hits in twenty at bats.
Even though many baseball fans from the Dutch Kingdom may have thought that Sharlon Schoop would start the season at AAA, he has been appointed to the roster of the Bowie BaySox (Orioles) in the AA Eastern League. Sharlon played all infield positions last season.
With the Norfolk Tides, he played four flawless games at third base. At shortstop he played only four games with the Baysox but he did not commit an error with them as well. He played 54 games at second base (47 with the Tides) in which he committed six errors (.978 fielding percentage). At first base he played five games with the BaySox in which he stayed perfect. Even though his defense is pretty good, he has some problems with handling the bat as he finished the season with an overall average of .219.
For some players that are on Rookie league rosters or on A Short Season rosters it is too soon too tell. They may be moved up before the seasons of those leagues start.
So far there is no information available for players like Ozhaino Albies, Christopher Garia, Calten Daal, John Polonius and Ray-Patrick Didder. But that may change any time soon.
