Several players from the Orioles’ minor league system are participating in the various Caribbean leagues. There are a couple new additions to this week’s list – catcher Jose Reyes, who is playing for the Estrellas in the Dominican Winter League, and infielder Mike Costanzo, who is playing for Caguas in the Puerto Rican Winter League.

I’ve attempted to compile a complete list, but I may have missed some players because it’s difficult to acquire information about the leagues. Feel free to get in touch with me if you think someone was inadvertently omitted and I’ll include them in next week’s entry.

Look for reports from the Caribbean leagues to appear on O’s on Deck every Wednesday for the remainder of the season.

Here are updates through Monday’s games on the players in the Orioles’ system:

Dominican Winter League

Fredy Deza, RHP – Deza pitched a scoreless inning against Escogido on Monday, but he’s struggled for most of the winter. The 25-year-old relief pitcher has an 8.49 ERA in 10 appearances for the Azucareros. He’s allowed 18 hits and three home runs in 11 2/3 innings. Opposing hitters are batting .360 against Deza., so there’s definitely plenty of room for improvement before the season ends.

Wilfredo Perez, LHP – The 24-year-old left-hander is 1-1 with a 7.11 ERA in eight appearances for the Estrellas. Perez has walked seven hitters and has eight strikeouts in 6 1/3 innings this season. He suffered the loss against Licey on Nov. 18 after allowing two runs without retiring a hitter. Perez bounced back with a strong outing against Escogido on Nov. 21. He struck out four batters and didn’t allow any base runners in 1 2/3 innings.

Jose Reyes, C – One of the newest additions to the organization, Reyes is hitting .222 (4-for-18) with two RBIs and two runs scored in 11 games for the Estrellas. The 25-year-old catcher has two walks and four strikeouts this season, and all four of his hits have been singles. In his best performance so far in the Dominican Republic, Reyes was 2-for-3 with a walk and two runs scored against the Gigantes on Oct. 26.

Alfredo Simon, RHP – In his first two starts for the Gigantes, Simon is 1-0 with a 1.69 ERA. The 27-year-old right-hander earned the victory against the Azucareros on Nov. 21 after giving up one run and six hits in six innings. He had two strikeouts and didn’t walk anyone in the game. Simon allowed one run and four hits in 4 2/3 innings against Escogido in his first start on Nov. 14. Simon had a 6.23 ERA in four appearances (one start) for the Orioles in 2008.

Venezuelan Winter League

Victor Castillo, C – Castillo hasn’t played for La Guaira since going 0-for-2 with a strikeout against Lara on Oct. 22 in his only appearance. The 24-year-old catcher batted .231 with four home runs and 12 RBIs in 39 games for the Delmarva Shorebirds this season. He hit .294 with one home run and 27 RBIs in 81 games for Delmarva in 2007.

Carlos Rojas, 2B/SS – Rojas is hitting .211 (4-for-19) with three RBIs and two runs scored in 11 games for the Caribes. The 24-year-old infielder hasn’t played since he was 0-for-3 with a walk against La Guaira on Nov. 11. He batted .247 with two home runs and 38 RBIs in 120 games for the Bowie Baysox this season.

Oscar Salazar, 1B/3B/LF – Salazar continues to lead the Venezuelan Winter League in batting average. The 30-year-old utility player is hitting .436 with six home runs and 21 RBIs in 26 games for La Guaira. He is tied for fifth in the league with 24 runs scored. Salazar also has seven doubles, two triples and three stolen bases. He was 3-for-4 with two RBIs and three runs scored against Aragua on Nov. 18.

Steve Torrealba, C/1B – The 30-year-old backup catcher is batting .182 (4-for-22) with four RBIs and five runs scored in 12 games for the Caribes this season. Torrealba, who hit .283 with eight home runs, 26 RBIs and 16 runs scored in 37 games for the Baysox in 2008, was 0-for-2 with a walk against La Guaira on Nov. 16. He has also received some playing time at first base in Venezuela.

Puerto Rican Winter League

Miguel Abreu, 2B – Abreu is hitting .250 (2-for-8) with one RBI and two runs scored in three games for Ponce. The 24-year-old infielder was 1-for-4 with a walk and two runs scored against Caguas on Nov. 23. He batted .275 with six home runs and 43 RBIs in 116 games for the Frederick Keys in 2008. Abreu had 24 doubles, 21 stolen bases and 55 runs scored for the Keys.

Mike Costanzo, 1B/3B – The 25-year-old infielder has received playing time at both corner infield positions in Puerto Rico, but he’s struggling at the plate so far this winter. Costanzo is hitting .071 (1-for-14) with five strikeouts in four games for Caguas. He was 0-for-3 with two walks, a stolen base and a run scored against Ponce on Nov. 23. This is a very small sample size, so it will be interesting to see how Costanzo performs for the rest of the season.

Mexican Pacific League

Jeff Nettles, SS/3B – The 30-year-old infielder is hitting .262 with one home run and six RBIs in 19 games for the Mochis Caneros, but he hasn’t played since Nov. 2. Nettles has hit successfully in eight of his past 10 games. During that span, he is batting .355 (11-for-31) with five RBIs and three runs scored. Nettles is only 2-for-13 with runners in scoring position.
