Signed as a non-drafted free agent out of Aruba in 2014, Didder is a plus athlete with quick-twitch actions who projects as a Role 45 fourth outfielder capable of handling the OF-5 role of holding down center field. The Fire Frogs have been testing that athleticism all year, with Didder playing four positions, including 32 games in center field, 26 in right field, and six games each at shortstop and second base so far. I saw him play a game in center field and a game at shortstop during this homestand.

At the plate, Didder projects as a below-average hitter with well-below-average power who can draw his share of walks, as seen by the big delta between his average (.205) and OBP (.321), which is consistent with his numbers (.274/.387) last year at Class A Rome, which was his first full pro season. His weakness is in his mechanics, where he has trouble catching up to velocity because of a high hand position and a downer hitch in his swing, all from an open stance to make for lots of moving parts. His double-plus speed (4.1 seconds from home-to-first base) certainly helps him get on base and take the extra bag when he can reach the gaps, but his approach is basically to hunt his weakness – fastballs. It has led to a jump in his strikeout rate at the High A level (to 26%), after striking out in 17% of his plate appearances last year. Overall, there is limited projection for the hit tool.

On defense is where the profile is rooted, and he looks the part of a plus-graded center fielder with good instincts for the position. He showed plus reads and reactions and plus range thanks to his speed I my look. While he has only been tested in center field and right field to-date, he shows the tools to be able to handle all three outfield positions. Though a limited look at shortstop, he did not show the body control necessary to project as an infielder. In lieu of some tweaks to his mechanics and approach at the plate, the profile should top out as a defense-first extra outfielder in the big leagues, with limited potential with the bat.
