I just found out that 5 of our guys are playing in the Puerto Rican Winter League. The regular season spans from 11/7 to 1/4 with the playoffs from 1/5 to 1/15.
The most interesting one definitely has been Eduardo Rivera. The 21 y/o 6'7 LHP from San Juan was a '21 11th round pick by the A's (same round Red Sox drafted Niko Kavadas).
Rivera was pitching poorly for the High-A Stockton Ports. He was placed on the Restricted List on May 16th & released on May 21st, which is a bit of a red flag.
Anyway, the Red Sox signed him on June 13th (his 21st birthday) & he pitched meh in the FCL for a bit before being promoted to Salem where he pitched well in his 6 appearances, including 2 where he pitched 4 scoreless & 2 with 3 scoreless. He also struck out 8 in each of his last 2 outtings.
Overall with Salem:
6 games, 22.2 IP, 1.99 ERA, 0.93 WHIP, 2.8 bb/9, 11.9 k/9.
Rivera made his Puerto Rican Winter League debut last off season with Cangrejeros de Santurce. This roughly translates to the Santurce Crabbers. He pitched 20 innings with a 3.15 ERA, 4.5 bb/9, 5.4 k/9.
So far this season for Santurce, Rivera has 24.2 IP, 1.09 ERA, 0.93 WHIP, 2.2 bb/9, 15 k/9... that's 41 strikeouts to 6 walks.
Overall it does seem to be a pitcher's league, with his 13-12 team posting a 2.83 ERA, but no one else on his team has more than 21 strikeouts. Eduardo has struck out 41.4% of batters faced. His teammates, including old friend Felix Doubront, have struck out 19.9% of batters faced.
Anyway, I would expect Rivera to start this next season at Greenville & it will be interesting to see if he's becoming someone worth paying attention to.
