Roderick Bernadina - OF Bernadina played four games in a Keys uniform in 2012 and registered just one hit—a grand slam. His eighth inning blast helped the Keys to a 10-5 victory at Wilmington on July 23. He was promptly sent back down to Delmarva after the four-game series with the Blue Rocks, but should get the chance to build on his Frederick stats in 2013. A 6-1, 162 pound native of Curacao, the right-handed Bernadina will enter his fourth season in professional baseball come April. His left-handed brother, Roger, an outfielder for the Washington Nationals, spent six seasons in the minors before making his major league debut. After the 2011 season, Baseball America rated Baltimore's Bernadina the 22nd best prospect in the organization.
Trent Mummey – OF Having made five trips to the disabled list in the last two seasons, Mummey's high on the list of potential Keys in search of a comeback season. A fourth-round pick out of Auburn in 2010, the left-handed center fielder three times ended up on the DL in 2012 with hamstring and concussion injuries and hit .228 with four home runs, 14 doubles, 22 RBI in 72 games. He also stole 15 bases. Previously rated as high as 15th in the Baltimore system by Baseball America, the 5-9,167-pound Mummey hit .336, slugged .797 and blasted 17 homers during his senior season in college. In his first game with Frederick in 2011, Mummey went 4-for-6, drove in five runs and was just a home run shy of hitting for the cycle.
David Walters – RHP Walters became the Keys workhorse at the back end of their bullpen in 2012, appearing in a team-high 45 games and leading Frederick in saves with 12. A 6-2, 200-pound right hander, Walters spent all of 2012 with Frederick after spending 2011 in Delmarva where he also led the Shorebirds in appearances (48) and saves (30) and finished with a 3.93 ERA. His ERA fell to 3.55 last season and he improved his strikeout rate from 6.6 per nine innings in 2011 to 7.9 per nine innings in 2012. Walters, 25, signed with Baltimore in 2009 as a non-drafted free agent after a four-year college career. He spent his junior and senior seasons at Division II's Francis Marion University in South Carolina, helping his team to a league title and NCAA tournament appearance in his senior season.
Brenden Webb – OF Since being selected by the Orioles in the 30th round of the 2009 first-year player draft, Webb has steadily climbed through Baltimore's system. He split 2011 between Delmarva and Frederick. A 6-3 left-handed outfielder with good speed, Webb hit .270 in his 23 games with the Keys last season after hitting .251 in Delmarva before being promoted. He also stole a career-high 19 bases and had an on-base percentage over .400—also a personal best—despite striking out 138 times in 124 games. The Orioles selected Webb, 22, after just one season at California's Palomar Junior College where he hit .342 with six doubles, two triples, eight home runs and 40 RBI. Webb, rated by Baseball America as the Orioles' 27th best prospect, slugged .553 at Palomar and showed off that pop during his late-season stint with the Keys, hitting three home runs and slugging .500 during his time in Frederick.
Eduardo Rodriguez – SP A lanky southpaw with a tailing fastball that registers in the low 90's, Rodriguez started 22 games for low Class A Delmarva as a 19-year –old in 2012. Signed by Baltimore out of his native Venezuela in 2010, he compiled a 5-7 record with a 3.70 ERA last season, striking out 73 batters and walking 30. He dominated Rookie Ball in the Dominican Summer League and the Gulf Coast League, posting a 2.33 ERA in the DSL in '10 and a 1.81 ERA in the GCL in '11. Likely a top of the rotation starter for the Keys in 2013, Baseball America ranks Rodriguez (6-2, 175 pounds) as Baltimore's fifth-best prospect overall and the Orioles' third-best pitching prospect, behind only Dylan Bundy—former Key and the top pitching prospect in all of baseball—and 2012 first-rounder Kevin Gausman. If Rodriguez makes it to Baltimore he would be the first Venezuelan player in O's history to be signed, developed and promoted to the majors by the organization.
