I'm not sure how instructive the category of "definite major league starter" is in a trade with prospects. Fried has big upside. Here's BA prior to the 2014 season on those two:

Born: Jan. 18, 1994. B-T: L-L. Ht.: 6-4. Wt.: 185. Drafted: HS—Studio City, Calif., 2012 (1st round). Signed by: Brent Mayne.

Background: The seventh overall pick in 2012, Fried paired with fellow Harvard-Westlake School product Lucas Giolito, now the Nationals’ No. 1 prospect, to become the seventh pair of high school teammates selected in the first round of the same draft. Signed for $3 million, Fried advanced to low Class A Fort Wayne in 2013 and made all 23 of his starts in a six-man rotation. His strikeout (7.6 per nine innings) and walk (4.2) rates ranked among the highest in the Midwest League for ERA qualifiers.

Scouting Report: Fried can spin a plus curveball and has two other pitches that scouts grade favorably, but what enhances his ceiling is the projection remaining in his lean 6-foot-4 frame. He fires 90-91 mph fastballs and tops out at 95 in each start—doing so from a textbook delivery and clean arm action—and scouts project a future plus fastball once he’s done filling out. Fried’s power curve turns the most heads for its tight rotation and top-to-bottom spin, and it was responsible for claiming the most strikeout victims. His changeup came a long way in 2013 as he began incorporating into his everyday repertoire. The Padres believe Fried’s walk rate will drop once he challenges hitters more frequently in the zone.

The Future: A three-pitch lefty who misses bats and has a good pickoff move, Fried will zoom through the minors if he throws more strikes. He has No. 2 starter upside, with a chance to jump quickly to Double-A if he excels early at high Class A Lake Elsinore in 2014.

Jace Peterson

Born: May 9, 1990. B-T: L-R. Ht.: 6-0. Wt.: 205. Drafted: McNeese State, 2011 (1st round supplemental). Signed by: Kevin Ellis.

Background: At McNeese State, Peterson starred on the diamond and as a cornerback on the football team. Each passing year reinforces the notion that he made the right decision in pursuing baseball. He spent all season as shortstop at high Class A Lake Elsinore, ranking among the California League leaders in average (.303), stolen bases (42) and triples (13), while establishing personal bests for average, on-base percentage (.382) and slugging (.454).

Scouting Report: Peterson has no single plus tool, but he combines athleticism, skill and instincts well, so his average tools play. He displays average range and arm strength at shortstop to go with throwing accuracy and first-step quickness. That quickness, combined with his ability to read pitchers, makes up for his below-average run times, as evidenced by a career 80 percent stolen-base success rate in 165 career attempts. Peterson shows no give in left-on-left matchups (batting .342 in 196 full-season at-bats in such situations) and sprays line drives where the ball is pitched, unafraid to use the big part of the park. Though he has below-average power, he collected a career-high 37 extra-base hits in 2013 and can turn on the inside pitch when he’s geared to do so. The organization lauds both his strike-zone discipline and leadership qualities.

The Future: If he reaches his ceiling, Peterson would be a table-setting shortstop on a contender, and he could be ready for San Diego within two seasons. He’s headed for Double-A in 2014.
