Dominican Winter League
- A's first-baseman Brandon Allen is participating in the Dominican Winter League in an attempt to get back on-track at the plate after a rough finish to his 2011 season. Through 10 games, he is continuing to struggle. Allen does have two homeruns for the Estrellas de Oriente, but he is only six-for-36 with four walks (one intentional) and nine strike-outs. He has also been caught stealing once and has committed an error. Allen has appeared exclusively at first base thus far.
- New acquisition Eliezer Mesa is a bench player for the Estrellas. He has one at-bat in two games and he struck-out in that one appearance. Mesa was acquired as the player-to-be-named-later in the Mark Ellis deal.
- Free-agent-to-be Lenny DiNardo has made two starts for the Gigantes del Cibao. In 9.1 innings pitched, he has a 3.86 ERA and five strike-outs against one walk. He has allowed 13 hits. DiNardo pitched for Double-A Midland and Triple-A Sacramento this season.
- A's starter Graham Godfrey is also in the Dominican this winter after pitching in Puerto Rico last winter. Godfrey has made two starts for the Leones del Escogido. In eight innings pitched, he has a 4.50 ERA and seven strike-outs against one walk and one hit-by-pitch.
- Sacramento lefty Jordan Norberto is pitching for the Leones, as well. In 2.2 innings, he has allowed one run and has five strike-outs versus two walks over four appearances. Norberto has one win and two holds.
- Stockton closer Jose Guzman is suiting up for the Toros del Este this winter in his native Dominican Republic. Guzman was set to be a minor league free agent this winter, but the A's re-signed the right-hander. He has made two appearances for the Toros thus far, and has allowed two runs in one-third of an inning.
- Midland reliever Jonathan Ortiz is pitching well for the Tigres del Licey. Ortiz has a 1.80 ERA and a 1-0 record after six appearances. He has struck-out two and walked two in five innings.
Venezuelan Winter League
- A number of A's farmhands are expected to participate in the Venezuelan Winter League later in the season. Right now, however, only Leonardo Gil has made an appearance in a game. Gil has had only one at-bat for the Leones del Caracas and he struck-out in that at-bat.
Mexican Winter League
- A's infielder Adam Rosales had been playing with the Aguilas de Mexicali, but he was placed on the inactive list on October 20 and has yet to return to the Aguilas. Rosales hit .200 with two RBIs and four walks in seven games (25 at-bats) before being made inactive.
- Arizona Rookie League starter Andres Avila is pitching for the Caneros de los Mochis this winter. Avila has struggled in seven outings. He has a 9.95 ERA and has allowed two homeruns in 6.1 innings pitched. He has also walked an uncharacteristic five batters while striking out five.
- Sacramento starter Carlos Hernandez has made two starts for the Tomateros de Culiacan. He is currently sidelined with a minor oblique strain, although the injury is not expected to keep him out long-term. In nine innings thus far, he has a 5.00 ERA and eight strike-outs against three walks.
Arizona Fall League
- Michael Choice continues to generate buzz for the Phoenix Desert Dogs. Despite missing a week of action, Choice is second in the league in homeruns with five in only 43 at-bats. He also has six walks and is batting .326 with an 1164 OPS in 11 games played.
- Grant Green was an extra-innings hero for Phoenix on Wednesday when his 11th-inning solo blast won the game for the Desert Dogs. He has two homeruns this fall and is batting .276 with an 800 OPS. He has struck-out 18 times against only four walks, however.
- Ryan Ortiz is furthering his reputation for getting on-base regularly. He has six walks in only eight games and is batting .273 with a .387 OBP for the Desert Dogs.
- Dusty Coleman is a member of the Phoenix taxi squad, meaning he is only eligible to play on Wednesdays and Saturdays. In the seven games he has appeared in, Coleman is batting .115 with 13 strike-outs in 26 at-bats.
- Tyson Ross has made four starts for Phoenix, all of which have been two innings in length. He has allowed four runs and has eight strike-outs and only two walks.
- Murphy Smith has been on a longer leash, racking up 15.2 innings in five starts for Phoenix. He has struggled in the later innings of each of his outings and has a 12.64 ERA. He has allowed 29 hits and three homeruns.
- Anthony Capra has alternated good outings with bad this fall for the Desert Dogs. He has a 15.88 ERA in 5.2 innings overall. In three of his outings, he has allowed one run with four strike-outs and one walk in three innings. In his other three outings, he has allowed nine runs with two strike-outs and six walks.
- Andrew Carignan has been mostly flawless for Phoenix, with the exception of one bad outing during which he allowed four runs in two-thirds of an inning. For his other six outings, Carignan has given up only one run on two hits and three walks with 10 strike-outs in 6.1 innings pitched.
