All the usual winter leagues are playing baseball, but there is not a lot of news.
Jose Miranda has played 15 games for the Criollos de Caguas in the Liga de Roberto Clemente. He is playing third base, batting 3rd or 4th, .302 BA and 849 OPS.
Celestino had started the year in the Dominican for the Gigantes and played 4 games in November. Then there was a league-wide Covid pause for over a week, and he hasn't played since. There are huge roster changes in this league, and there could be plenty of reasons why he is not currently playing. Fernando Romero played for the same team, but hasn't played since signing in Japan.
Astudillo is playing mostly LF in Venezuela for the Caribes, batting 5th with 914 OPS.
Tomas Telis plays for the same team as catcher or1B, bats third with 821 OPS.
Lachlan Wells is pitching for Sydney (is he still our property?). They are just getting started, it seems.
There could be others. With no minor league box scores last year, I am not as familiar with Caribbean prospects in particular.
In the olden days you could just go to mlb/stats/offseason leagues and click on the Twins logo to see the stats for all the Twins players in the winter leagues. Apparently mlb has lost so much money they can't do that anymore (or there is something about my computer). I have heard it said that mlb tried to get funding for several full-time employees to do this work in the recent stimulus bill, but my sources deep within Congress said someone influential who lost his minor league team squashed it. And including the Venezuela stats raised alarms.
