Rivera punishes himself for mistakes and sometimes becomes visibly frustrated after poor takes at the plate. His performance suffered in 2017 due to anxiety. While he has gotten it under control to an extent, he may not be able to handle major setbacks well. He's channeling that nervous energy for now and is hard worker.

MLB ETA Risk Factor OFP Realistic Role Video

Tool Future Grade Report
Hit 45 20 at present; susceptible to sliders and pitches below the zone; struggles with front-foot hitting and often attacks pitches too early; vulnerabilities become worse with two strikes; his future hinges on whether he can overcome his aggression.
Power 60 Every ball in play is impressive; even flyouts and popups are towering; muscle over bat speed power; 25-30 HR hitter if he can get consistent at-bats and the hit tool comes together.
Baserunning/Speed 30 40-grade times for now; projects to get slower as he gets older but not as much as most; makes more than his fair share of miscues on the bases and sometimes loses track of coaches/where the ball is; not a complete liability on the bases but he's almost there.
Glove 50 This grade assumes the transition to first is permanent, he's a circus in the outfield; has plenty of wingspan to scoop throws in the dirt or snag errant pickoff throws; reaction times improving with reps; he'll make all the plays he has to but won't impress.
Arm 50 Unlike the glove, his arm works better in the outfield than at first. He has plenty of strength but is relatively new to regular play in the infield and is uncomfortable finding an angle at which to execute throws to second.
Overall

I've rarely heard higher praise for a player than Lance Parrish's comment on Rivera: "He's superman strong." That encapsulates where his value lies quite nicely. Outside of his power, Rivera offers very little. He isn't a liability on defense as long as Detroit keeps him at first base, but everything boils down to what he can do in the batters' box That's why the hit tool scares me so much. He could stall out as low as High-A if he doesn't fix his timing and load issues. He could just as easily stall out when faced with good pitching thanks to his extraordinarily aggressive approach, particularly against pitches below the zone, which he has a very hard time letting go.
