Just for reference, Kjerstad had more HR, more RBIs, and almost identical OPS (1.011-1.007) to Martin. Hitting nearly .350 career in the SEC isn't easy to do.
He's a bit of an awkward athlete but for his size he isn't slow at all once he gets going. Long, lanky strides. He still looks like he could add on to his frame and has room to grow some more. Still looks like he's about 16 in the face lol.
He does have some weird mental baserunning errors and he made some mistakes defensively when he was in LF that made you scratch your head, but he seemed much better in RF. Played a little bit of 1B too. He also made some outstanding plays in the outfield so you can tell he has the athleticism to make them just doesn't do it consistently. Robbed a home run against Dallas Baptist a few years ago in the Regional by climbing the outfield wall.
Also plays with a bit of an attitude:
