On WEEI earlier this week, Red Sox general manager Theo Epstein said that the team’s farm system is still well-stocked, even with the off-season trade that sent Casey Kelly, Anthony Rizzo and Reymond Fuentes to San Diego for Adrian Gonzalez.

The Red Sox have interesting prospects at every position (including catcher Ryan Lavarnway, third baseman Will Middlebrooks, shortstops Jose Iglesias and Xander Bogaerts, first baseman Miles Head and infielders like Garin Cecchini, Kolbrin Vitek and Oscar Tejeda). Boston’s pitching depth is strong with arms like Felix Doubront, Kyle Weiland, Alex Wilson, Anthony Ranaudo and 18-year-old Raul Alcantara. Yet it is the outfield where the Red Sox have the greatest depth, and the area that offers the most trade chips.

The debate rages about whether the Red Sox should trade prospects for Carlos Beltran or a starting pitcher like Ubaldo Jimenez. And there are discussions about Boston acquiring a lower profile bat, like the right-handed hitting outfielder Reed Johnson of the Chicago Cubs.

If Epstein does make a trade, chances are an opposing team will reach into Boston’s treasure chest of outfield prospects. Among the most appealing are:

• Josh Reddick – Entering the season Ryan Kalish was Boston’s top-rated outfield prospect – and he is still highly regarded by the Sox – but a shoulder injury and subsequent neck pain has kept Kalish on the disabled list, opening an opportunity for the 24-year-old Reddick. All he has done is hit .378 with four home runs, 19 RBI and a 1.102 OPS in 82 at-bats and 95 plate appearances. The versatile and athletic Reddick proficiently plays all three outfield positions.
• Ryan Kalish – A year younger than Reddick at 23, the left-handed hitting Kalish is a plus defensive player at all three outfield positions and can impact the game at the plate, in the field and on the basepaths. Even though his season has been limited because of the shoulder injury and neck pain, Kalish is still a candidate for Boston’s starting right field job in 2012. Yet he will need to get healthy and prove himself again to show that his shoulder injury is behind him.
• Chih-Hsien Chiang – Signed as an international free agent out of Taiwan in 2005, the left-handed hitting Chiang was just a fringe prospect until his breakout 2012 season. Now 23, Chiang is hitting .331 with 17 home runs, 70 RBI and a 1.036 OPS. His success this year is partly attributed to his commitment to effectively managing his Type 1 diabetes. He was initially a second baseman but struggled there and was moved to the outfield, where he has above-average range and a strong arm but is still learning to play the position.
• Bryce Brentz – Boston’s first round pick in 2010 out of Middle Tennessee State, where he won the NCAA Division I batting title, the 22-year-old Brentz hit .359 with 11 home runs, 36 RBI and a 1.061 OPS in 170 at-bats this season before earning a promotion to advanced Single-A Salem. He has tasted success in the Carolina League as well, batting .279 with 10 home runs, 27 RBI and a .929 OPS in 122 at-bats. He has 20 home runs in 71 games this season overall, missing three weeks on the disabled list shortly after his call-up to Salem. Unlike most of the organization’s top outfield prospects, Brentz hits from the right side.
• Brandon Jacobs – A 10th round pick out of high school in 2009, the athletic Jacobs was committed to Auburn as a running back until the Sox lured him to baseball with a healthy signing bonus. Now 20, Jacobs is still raw, but he has dramatically improved his left field defense and is hitting .318 with 13 home runs, 56 RBI, 22 stolen bases and a .921 OPS in 314 at-bats at Greenville.
•  Alex Hassan – Talk about athletic. Hassan was drafted by the Sox in the 20th round in 2009 out of Duke as a pitcher, but he was converted into an outfielder when the club saw him hit in the Cape Cod League that summer. Hassan did play the outfield at Duke and hit .324 in his last season. He has continued that success swinging a wooden bat in the minors. The Milton, Mass. native is batting .304 with eight home runs , 46 RBI and an .889 OPS. Hassan has a patient plate approach and works the count, as his .430 on-base percentage indicates. The 23-year-old Hassan is not mentioned in the same category as Reddick and Kalish, or even with Chiang, Brentz and Jacobs, but he is emerging as a promising prospect worth watching.
• Che-Hsuan Lin – An international free agent signed out of Taiwan in 2007, Lin is highly regarded for his exceptional outfield range and strong arm, and his speed on the basepaths. He has limited power but has hit respectably in the minors, batting .275 at Portland last season and hitting .268 there earlier this year before his promotion to Pawtucket, where he has a .272 average with one home run and 17 RBI in 184 at-bats.
• Jeremy Hazelbaker – A fourth round pick out of Ball State in 2009, Hazelbaker earned a promotion to Double-A Portland after hitting .279 with five home runs, 14 RBI and 12 stolen bases in 122 at-bats at Salem this season. The 23-year-old Hazelbaker is not a top prospect, but he does have major league potential with his speed and power potential. He swiped 63 bases last year at Greenville. In 217 at-bats at Portland, he is hitting .244 with six home runs, 24 RBI, an .864 OPS and 17 stolen bases.

Right now, Kalish and Reddick project as top prospects while Brentz, Jacobs and Chiang are second-tier prospects. Lin, Hassan and Hazelbaker are likely fourth outfielders at the major league level, at least in Boston. Yet Hassan and Hazelbaker could emerge into starting outfielders in the majors if they continue to improve.

This list does not include promising youngsters like this year’s second round pick Williams Jerez (signed out of high school) and 19-year-old Henry Ramos (already playing at Greenville), who are in the early stages of their development.
