Projecting the Prospects in the Evan Longoria Trade
The Giants have acquired Evan Longoria from the Rays in exchange for major leaguer Denard Span, plus prospects Christian Arroyo, Matt Krook, and Stephen Woods.
Below are the KATOH projections for the prospects received by Tampa Bay. WAR figures account for each player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings. In total, my KATOH system projects these prospects for a combined 2.4 WAR (2.2 by KATOH+) over their first six years in the majors.

Christian Arroyo, IF (Profile)
KATOH: 1.5 WAR
KATOH+: 1.8 WAR
Arroyo missed a large chunk of 2017 due to multiple hand injuries and hit just .192/.244/.304 in 34 games with the Giants. Even without accounting for his small-sample big-league struggles, though, Arroyo’s track record doesn’t portend particularly great things. He hit a punchless .274/.316/.373 at Double-A in 2016 and his small-sample success at Triple-A last year was largely aided by his .427 BABIP. Arroyo’s youth and contact skills make him interesting, but he has very little power or speed and has already more or less moved off of shortstop.
