SAN DIEGO -- The Padres have gone to great lengths to rebuild their farm system this winter, adding a handful of Top 30 Prospects that could strengthen their big league team down the road.
With the beginning of Spring Training around the corner, MLB.com will preview the Padres by taking a glance at several areas of the team note heading toward the report date for pitchers and catchers on Thursday.
OF Manuel Margot: Margot became the Padres' No. 1 prospect at the very moment the trade traded for him (the Craig Kimbrel deal with the Red Sox). He's an athletic center fielder who is nowhere near his ceiling. Margot's hit tool is good and should improve with time. But he'll need to get better against right-handed pitching and improve his on-base skills. He's at least a year away. If the Padres don't rush him, they could eventually have a fine player on their hands.
OF Hunter Renfroe: Renfroe, the team's No. 2 prospect, should arrive in the big leagues at some point in 2016. He continues to be what the Padres thought he would be: A player with big, raw power who strikes out too much and good athlete with a cannon for an arm. Renfroe had 52 extra-base hits last season in two Minor League stops. He will likely open the season with Triple-A, but he could earn a promotion if he shows he can cut down on his strikeouts.
SS Javier Guerra: While Margot might have been the marquee return in the Kimbrel deal, Guerra wasn't far behind. The Padres can easily envision him as their shortstop of the future, even if that future might very well be two seasons away. Guerra, the club's No. 3 prospect, showed pop at the plate for the first time last season, slugging 15 home runs. He won't turn 21 until September, so he'll need a lot more seasoning in the Minor Leagues before he's ready to join the big league team.
SP Colin Rea: Rea, the team's No. 4 prospect, wasn't really considered a big prospect a year ago at this time, but his stock skyrocketed after early success with Double-A San Antonio, which earned him a spot in the Futures Game. Rea then showed mostly well in a six big league starts. He'll have a chance to win a job at the back end of the rotation, but will face some strong internal competition this spring from Robbie Erlin, Carlos Villanueva and Brandon Morrow, among others.
