The 27-year-old former first-round pick (No. 10 overall, 2011) debuted with the Friars back in 2014 and has spent parts of the past five seasons in the San Diego infield mix. However, after a mostly promising start to his career — .274/.330/.408, 107 OPS+ in 410 plate appearances from 2014-15 — Spangenberg’s bat has fallen off. He’s batted .251/.312/.384 (88 OPS+) through 868 big league PAs from 2016-18. The 2018 season, in particular, was tough on Spangenberg, as his OBP dipped below .300 and his strikeout rate soared to 32.8 percent.
Spangenberg has more than 1000 innings of MLB experience at both second base and third base, though he hasn’t graded out as a plus defender at either. Both Defensive Runs Saved and Ultimate Zone Rating peg him as roughly a scratch defender at second but a below-average third baseman.
The left-handed-hitting Spangenberg has been a solid bat against right-handed pitching throughout his career (.271/.331/.423), and paired with his respectable glovework at second base, he could at the very least function as a useful platoon piece in that role. Spangenberg won’t turn 28 until next March, though, so it’s certainly not out of the question that a change of scenery could help him tap into the potential he demonstrated earlier in his career. Any team that signs Spangenberg could control him through the 2020 season if he’s able to bounce back next year, as he’d remain arbitration-eligible next winter.
