1. Outfielder Brandon Jacobs from the White Sox
Not to be be confused with the New York Giants' running-back [Texas are the only team to sign NFL players!], the 23-year-old Jacobs batted .244 with 13 home runs and 66 RBI in 127 games between Single-A Salem and Double-A Portland in the Boston Red Sox system, and Double-A Birmingham in the White Sox organization. Jacobs was a 10th round pick in 2009, and is a career .262 hitter with 115 doubles, 49 home runs and 238 RBI over five Minor League seasons. He entered the 2013 season rated by MLB.com as the #11 prospect in the Boston system, and was traded to Chicago on July 12, for left-handed pitcher Matt Thornton.
2. Right-handed pitcher A.J. Schugel from the Angels
Perhaps the most interesting thing is that Schugel, 24, was converted from an infielder at Central Arizona College, and hadn't pitched before 2010. He made 19 starts with Triple-A Salt Lake in 2013, going 4-6 with a 7.05 ERA over 89.1 IP. That was disappointing, as in 2012, he led the Texas League with a 2.89 ERA over 140.1 IP and 27 starts, being named to the league's mid- and postseason All-Star Teams. Overall, he has a 4.02 ERA in four minor-league seasons, and a K:BB ratio of 2.09. He's on Twitter if you want to give him a follow: @schug_knight. A 25th-round pick by the Angels in 2010, his father, Jeff, was recently hired by the Braves as a special assistant to general manager Frank Wren.
3. Outfielder Todd Glaesmann from the Rays
This looks to be another player looking to bounce back, as the 23-year-old Glaesmann, took a step back after being named the Rays' 2012 Minor League Player of the Year, going .285 with 21 home runs and 75 RBI in 127 games at Single-A Bowling Green and Single-A Charlotte. However, this year he only hit .240 with 11 home runs and 54 RBI in 132 games for Double-A Montgomery. Across five Minor League seasons he has batted .252 with 40 home runs and 176 RBI in 400 games. Glaesmann was rated by Baseball America as the Best Power Hitter in the Rays' farm system prior to this season, and was selected by then in 2009's third round. He's also on Twitter: @toddglaesmann22.
None of the three are what you'd call a lock for the majors, but they're intriguing and all of them appear to have some potential. However, Schugel and Glaesmann in particular, need to rebound this year, if they're going to maintain any kind of progression.
