The Rangers’ decision to cannonball into the deep end of the free-agent pool this offseason has radically reshaped their infield mix and given them one of the top offensive double-play tandems in Major League Baseball. Corey Seager and Marcus Semien are slated to hold down the shortstop/second base pairing in Arlington for the next seven seasons.
One side effect of that seismic splash is that it leaves Isiah Kiner-Falefa without a clear-cut defensive home. A Gold Glove winner at third base in 2020, Kiner-Falefa played a strong shortstop in 2021 and had been squarely atop the depth chart there prior to the Seager/Semien stunner. That’s no longer the case, though not through any fault of his own. Kiner-Falefa has been an elite fielder by measure of Defensive Runs Saved and finished third among MLB shortstops in the Fielding Bible’s voting this past season. Metrics like Ultimate Zone Rating and Outs Above Average aren’t as bullish, but Kiner-Falefa is at worst regarded as a roughly average defender (and generally agreed upon as a good bit more than that).
Beyond his accolades with the glove, Kiner-Falefa is fairly a solid performer at the plate, albeit in more of an “old school” manner. He’s been 13 percent worse than the average hitter, by measure of both wRC+ and OPS+, over the past two seasons — but that’s primarily due to a lack of power. Kiner-Falefa has still posted a solid .273 batting average and a respectable .316 on-base percentage in that time. He’s only drawn a walk in 4.6% of his past 905 plate appearances, but he’s also only fanned in 13.5% of those trips to the plate.
There’s plenty of value derived from Kiner-Falefa’s ability on the basepaths as well. He went 20-for-25 in stolen-base attempts this past season and ranked in the 75th percentile of MLB players in terms of average sprint speed, per Statcast. On top of that, Kiner-Falefa has played in all but six of the Rangers’ games dating back to 2020. Only six big league players have appeared in more games than Kiner-Falefa over those two years.
