Infielder Jedd Gyorko heads the UT San Diego's fourth annual list of the Padres top minor league prospects.

When colleague Tom Krasovic started the list, Kyle Blanks was in the No. 1 spot and the rankings went only 10 deep -- partially due to the state of the Padres farm system.

We've doubled the list the past two years and changed the criteria a bit. Reach the majors and you're off the list. I don't know if this is important to Casey Kelly, but he would have been in the top five under the old rules.

Without further delay, our list of top Padres prospects:

1.2B-3B Jedd Gyorko: Some scouts question his athleticism and defensive skills. But no one has questioned the bat. Gyorko, 24, hit .328 with 24 homers and 83 RBI in 92 games at Triple-A Tucson the second half of last season.

2.RF Rymer Liriano: The Padres believe the 21-year-old has five-tool potential and could be in the major leagues by the end of this season. Hit .357 in the Arizona Fall League after finishing 2012 as one of the younger players in Double-A.

3.C Austin Hedges: 2nd-round pick in 2011 draft hit .279 with 10 homers and 56 RBI while turning 20 at low Single-A. Midwest League All-Star. Defensive skills said to be close to Major League ready.

4.LHP Max Freid: Padres 1st-round pick (7th overall) last June had 3.57 ERA in Arizona Rookie League. He turns 19 next month and is 6-foot-4 with 95-mph fastball plus advanced curve and developing changeup.
