Somebody Save Julio Rodríguez

When the 2022 season opened to fanfare and excitement, one of the main talking points was the record-setting arrival of top prospects. After countless rebuilds, a global pandemic, and a prolonged lockout, fans deserved to watch budding superstars duke it out in games that matter. Some of them, like Seiya Suzuki and Jeremy Peña, have been thriving right out of the gate; both rank among the top ten in batter WAR as of Thursday’s games. Others like Spencer Torkelson might have fallen a bit off the radar but have still been successful per wRC+ or batted ball metrics.
Much to our annoyance, though, there’s always a flip side we’d like to ignore. Enter Julio Rodríguez, whose triple slash of .136/.208/.159 is terrible not just amongst fellow rookies, but also all of major league baseball. This isn’t to say we should be concerned; Rodríguez remains one of the most talented rookies around, and in the grand scheme of things, 12 games and counting mean next to nothing. Don’t smash that emergency glass just yet!
But in his opportunities to prove himself, Rodríguez hasn’t been offered fair terms. One of the most fundamental and effective traits a hitter can possess is plate discipline, which is partly the ability to ignore unfavorable pitches. It’s something Rodríguez has demonstrated several times in a limited number of plate appearances, with confidence to boot, but that bravado hasn’t quite translated into results:

This is a chart showing all eight (!) called third strikes outside the zone against Rodríguez, a league-leading total. The plotted strike zone is adjusted for his height, by the way, so there’s no ambiguity here. It gets even worse when you actually look at some of these pitches, which the umpires gift-wrapped for pitchers who made objective mistakes. For example, here’s a Sonny Gray sinker that is rarely, if ever, called a strike, especially in a two-strike situation:
Uh-huh. Sure, that’s totally a decision befitting a stadium named Target Field.
You could maybe argue that Rodríguez, whose two-strike swing rate of 40.3% is the third-lowest among all hitters, needs to up his aggression. The cost of taking a third strike is high, so the math tells us that a batter ought to hack away instead. But Suzuki has a similar two-strike swing rate (42.7%), and he’s yet to be punished for his passivity. Whatever flaws Rodríguez might have right now as a hitter don’t excuse the fact that very few calls have went his way. This is a clear problem, one that has Mariners fans understandably angsty.
