Tim Alderson: The A’s picked up the former Giants’ first-round pick as a minor league free agent signing during the 2014 season. He had a 4.11 ERA in eight appearances (seven starts) for the High-A Stockton Ports and took the loss in Game One of the Ports’ three-game playoff series versus Visalia. Alderson will be 26 next season.
Luis Baez: Baez was a mid-season Midwest League All-Star for the Low-A Beloit Snappers in 2014. Signed by the A’s out of the Dominican Republic before the 2008 season, the 23-year-old shortstop hit .237/.260/.344 for the Snappers this year. It was his fourth season in the States and his first in a full-season league.
Jeremy Barfield: Barfield, the A’s eighth-round pick in 2008, split his season between the mound and the outfield. An outfielder up until mid-season last year, Barfield was asked to make the switch to pitching. He dove into the opportunity and pitched well enough to pitch at High-A this season. He had a 4.63 ERA and 39 strike-outs in 35 innings for the Stockton Ports before deciding to return to hitting. He spent the rest of the year with Double-A Midland and batted .261/.387/.394. Barfield also had a strong post-season for Midland, batting .310 and helping the RockHounds win the Texas League title. He will bring some power, a decent eye at the plate and one of the best outfield throwing arms in minor league baseball to his next team.
Matt Buschmann: Buschmann signed with the A’s on a minor league deal last off-season. The Vanderbilt alum spent most of the season with Triple-A Sacramento and he had a 4.52 ERA in 133.1 innings. He struck-out 123 and walked 49. Buschmann will be 31 next year.
Nick Buss: Buss came to the A’s early in the 2014 season on a waiver claim off of the Los Angeles Dodgers’ waiver wire. The outfielder was later designated for assignment by the A’s and cleared waivers to remain as a non-roster player. The eighth-round pick in 2008 had a productive season for the A’s at the Triple-A level, hitting .307/.371/.380 with 14 stolen bases. Buss is currently playing in the Mexican Winter League.
Dusty Coleman: Coleman, a 28th-round pick of the A’s in 2008, hits the free agency market for the first time. He was the team leader for the Texas League champion RockHounds, hitting 18 homers and driving in 81 runs while playing above-average defense at short and providing leadership in the clubhouse. Coleman has power, speed and the ability to play shortstop at a high level. He shouldn’t have any trouble finding a job for 2015.
Manny Correa: Correa spent his entire career in the Angels’ organization before latching on with the A’s for 2014. Injuries limited his season to just eight starts. He had a 5.40 ERA in 36.2 innings for the High-A Stockton Ports. Correa is currently pitching in the Venezuelan Winter League.
Fernand Cruzado: Cruzado spent seven years pitching in the A’s system and never pitched higher than short-season ball, but his 2014 season was his best year to date. The right-hander made the mid-season New York-Penn League All-Star game and had a 1.90 ERA in 23.2 innings. He struck-out 20 and walked eight in 23.2 innings.
Omar Duran: Duran’s fastball has always ranked among the best in the A’s system in terms of velocity. However, his command and injuries slowed his progression through the A’s system until this season. The left-hander had a 2.35 ERA and a 61:22 K:BB in 46 innings with Stockton before earning his first promotion to the Double-A level. He finished the year on the Texas League champions’ roster, posting a 3.14 ERA in 14.1 innings in his first taste of upper-level baseball. Lefties who throw 95+ don’t grow on trees and Duran should have no trouble securing another contract.
Jose Flores: Flores joined the A’s on a minor league free agent deal before the 2014 season. The former Cleveland Indians farmhand started the year in Triple-A, but he struggled some, posting a 4.60 ERA and walking 17 in 29.1 innings. Flores was demoted to Double-A mid-season and he was a big part of the RockHounds’ post-season run. Serving as the Midland closer, he saved three playoff games and allowed runs in just one of six appearances.
Frank Gailey: Gailey was a minor league free agent the past two off-seasons and both off-seasons he signed on with the A’s. He will hit the open market again after two strong seasons at the Double-A level. In 2013, he had a 2.61 ERA in 62 innings and this year he had a 3.46 ERA in 52 innings.
Shawn Haviland: The A’s 33rd-round pick in 2008 out of Harvard, Haviland missed the entire 2013 season after injuring his elbow during the 2012 Arizona Fall League. He recovered well from the Tommy John surgery, posting a 3.81 ERA in 163 innings between High-A and Double-A in 2014. Haviland also made two starts in the post-season for the RockHounds. Haviland has a four-pitch mix and, two years removed from surgery, should find new employment.
Deryk Hooker: Hooker signed with the A’s as a minor league free agent before this season. Like Flores, he began the year in Triple-A, but found himself in Double-A after an up-and-down first-half of the year. Hooker pitched well in a swingman role for the RockHounds, posting a 3.45 ERA in nine relief appearances and three starts. Hooker had a spot start in the post-season for Midland that helped the RockHounds earn a win.
Philip Humber: The big league veteran and former top-10 round pick signed with the A’s as insurance for their big league bullpen in 2014. The A’s never brought Humber up from Triple-A, however. Humber made 44 appearances at the Triple-A level in 2014, all but three coming out of the bullpen. He had a 3.65 ERA and a 68:23 K:BB. Humber had primarily been a starter before this season, so now that he has a full season of relieving under his belt, he will provide some versatility for the next team that signs him.
Jonathan Joseph: Joseph hits the open market after pitching for nine seasons in the A’s organization. The Dominican right-hander has done everything the A’s have asked of him over the years, coming out of the bullpen, starting, pitching in long relief and pitching in the back-end of the bullpen. He has had success in a variety of roles, and 2014 was another solid season for Joseph. He appeared in 37 games for the Stockton Ports, with 34 coming out of the bullpen. In 78 innings, he had a 3.58 ERA and a 72:38 K:BB. Joseph has some life on his fastball, as well as two serviceable secondary offerings. The 26-year-old seems ready for a jump to Double-A with his next organization.
Jefry Marte: The A’s acquired Marte from the New York Mets before the 2013 season in exchange for Collin Cowgill. Marte was limited by leg injuries in 2013, but he appeared in 107 games for Midland in 2014. The third baseman hit .259/.333/.375 with a career-high 10 homeruns. Marte shows a lot of raw power in batting practice and he appears to be starting to tap into it. He has a good eye at the plate, as well. Defensively, Marte has some tools to work with, but he is still inconsistent at third. At just 23 years old, Marte still holds a lot of promise and could generate significant interest on the open market.
Jose Martinez: Martinez joined the A’s from the Houston Astros’ organization as a minor league free agent before the 2014 season. Martinez spent the season in Triple-A and logged 122 games played despite having a stint on the DL. He hit .276/.345/.376 with eight homers. Martinez is currently hitting .283 in the Venezuelan Winter League. He will have plenty of suitors this off-season.
Luis Martinez: Martinez signed on with the A’s during the final month of the minor league season after his release from the Angels’ organization. The backstop hit .150 in 14 games for the A’s in Triple-A. He hit .262/.329/.403 for Triple-A Salt Lake. Martinez has some MLB experience and he has a good arm and solid receiving skills. He’s likely to land with another organization on a minor league deal.
Jeremy McBryde: McBryde had an outstanding year in Triple-A for the A’s. Serving as a closer for the second half of the year, McBryde saved 17 games. He had a 2.22 ERA and a 66:26 K:BB in 65 innings. PCL batters hit only .181 against him. McBryde already signed on with another team for 2015, inking a major-league deal with the Angels.
Luke Montz: A shoulder injury that required surgery cost Montz much of the last two seasons, but he made a lasting impression on the A’s organization during his time with the club. The backstop hit for plenty of power and worked lots of walks at the plate, while bringing lots of leadership to the A’s Triple-A and Rookie ball clubs (he played in the AZL this season as he rehabbed his shoulder injury). Montz is currently playing in the Mexican Winter League. If his shoulder is sound, he should receive lots of interest on the open market.
D’Arby Myers: Injuries also cut into Myers’ playing time during his last two seasons with the A’s, but he showed promise when he was on the field. The former Phillies’ prospect signed with Oakland as a minor league free agent before the 2013 season. He re-signed with Oakland last year. Myers hit .285 in 118 games with the RockHounds in 2013 and had the longest hitting streak in the Texas League that year. A broken wrist cost Myers a significant amount of time this year, but he still hit a solid .305/.357/.418 in 59 games for the RockHounds. He also hit .313 during the post-season. Myers will turn 26 in December and seems poised to jump to Triple-A next year.
Darwin Perez: Perez opened a lot of eyes with a strong showing in major-league camp in 2013. The A’s re-signed him to a minor league deal for the 2014 season, but a spring training injury kept the middle infielder out all season.
Joe Savery: Savery spent the entire 2014 season on the A’s 40-man roster, pitching out of the A’s bullpen briefly. The rest of the year, he was at Triple-A. He had a 2.84 ERA and 45 strike-outs in 44 innings at that level. Savery has always had intriguing stuff and his command has improved out of the bullpen. The former first-round pick should receive plenty of interest on the open market.
Tim Sexton: Sexton joined the A’s as a minor league free agent during the final few weeks of the 2014 regular season. He made five appearances for Double-A Midland, posting a 5.91 ERA with 11 strike-outs and two walks in 10.2 innings. Sexton was a 2007 draft pick of the Dodgers and he has pitched for the Dodgers, Rockies and Padres organizations during his career.
Marcus Walden: The A’s claimed Walden off of waivers from the Toronto Blue Jays early in the season. He was sent to Triple-A as a starter and struggled in 11 starts. He had a 5.73 ERA and a 34:27 K:BB in 59.2 innings. After a demotion to Double-A, Walden moved into the bullpen, where he found a home. In 21 relief appearances for the RockHounds, Walden had a 3.79 ERA and a 26:13 K:BB in 35.2 innings. During the post-season, he was a star. In eight innings spread over four appearances, Walden didn’t allow a run and gave up just one hit. He struck out nine. The groundball specialist could continue in a relief role next year.
Kenny Wilson: Like Walden, Wilson was a waiver claim by the A’s from the Blue Jays mid-season. Also like Walden, Wilson began his time with the A’s in Triple-A, but played much better after a demotion to Double-A. In 14 Triple-A games with the A’s, Wilson hit only .135. With the RockHounds, however, he batted .327 and he stole seven bases in 27 games. Wilson will be 25 next season and should garner plenty of interest on the open market.
