In 2021, LA Angels closer Raisel Iglesias was arguably the best reliever in baseball.
In 2022, it’s safe to say that things haven’t gone quite as smoothly for the hard-throwing righty as he currently owns a less than ideal 4.64 ERA and is falling short of his own sky-high goals.
However, does Iglesias deserve all the blame for his bloated ERA, or is something else the cause?
LA Angels' Closer Raisel Iglesias is the victim of some incredibly bad luck in 2022.
Now, before we get into it, I’m not saying Raisel Iglesias is 100% blameless here or that his struggles are all on his LA Angels teammates, more so that there are some truly unlucky things affecting him that really shouldn’t be happening.
I know that not everyone fully trusts advanced stats when someone is struggling as much as Iglesias is, but just bear with me for a bit. When comparing Iglesias' ERA and FIP to some of their predictive counterparts, you’ll get an idea of just how unlucky he’s been this season.
- 2022: 4.64 ERA, 4.18 FIP | 3.68 xERA, 2.18 SIERA, 2.76 xFIP
2022 stats are through June 14.
Right off the bat you’ll notice just how similar his 2022 predictive stats are to 2021’s. His 2022 SIERA and xFIP in particular are notable as they are each the second-best marks of his whole career after 2021. For someone whose previous “worst” season came at the height of the juiced ball era in 2019 when he owned a 4.16 ERA (112 ERA+), you’d expect him to at least be outperforming that season right now.
Going even deeper, Iglesias’ SIERA and xFIP are also both in the American League’s top 10 among qualified relievers according to Fangraphs' leaderboards. It’s here that you’ll begin to understand just how unlucky Iglesias has been compared to the rest of the league’s top relievers. On both leaderboards, the next worst ERA among pitchers in the top 10 is 2.81.
Expanding on this further, among the top 50 pitchers by SIERA, only five more have an ERA above 4.50 vs. 32 with sub-3.00 ERAs. Likewise, for the top 50 pitchers by xFIP, there are again just five other pitchers with ERAs above 4.50 vs. 31 with sub-3.00 ERAs.
Keep in mind, all of this is going on while Iglesias continues to put up elite strikeout and walk numbers, as well as greatly limiting the total amount of contact he’s giving up, just like in 2021.
- 2021: 13.2 K/9, 1.5 BB/9, .207 BAA, .190 xBA, .288 BABIP
- 2022: 12.2 K/9, 1.7 BB/9, .225 BAA, .227 xBA, .283 BABIP
At this point, you’re probably asking what the actual problem is that’s causing Iglesias’ troubles. This is only speculation, but I believe I’ve come up with two possible sources that directly correlate to each other.
The first issue plaguing Raisel Iglesias at the moment is actually something in his direct control.
The LA Angels closer is currently getting killed by his sinker and slider like never before.
One possible cause for the bad luck affecting Raisel Iglesias is regression of his sinker and slider.
Throughout his career with the Cincinnati Reds and LA Angels, Raisel Iglesias has always struggled to make his sinker work, as it usually ends up generating the worst whiff rate and opposing AVG and SLG of any of his pitches. Pitch data from Baseball Savant shows that after lackluster results with it during his first few seasons, Iglesias dropped it from being his number one pitch to his fourth pitch by 2019.
In 2022, his sinker is seemingly worse than ever, generating an opposing BA of .389, opposing SLG of .611 and the worst whiff rate of any pitch in any season of his career at 8.8% (the previous worst was his 2015 sinker at 15.3%). To put this in context, of the 18 hits Iglesias has allowed this season, his sinker is responsible for more than any other pitch at seven, despite it only being his third most used pitch.
What makes all this truly mind boggling, however, is the fact that Iglesias is actually using his sinker at its highest rate since 2018 while simultaneously using his other three pitches at their lowest rates since 2018. From 2019-2021, he never used it more than 10.6% of the time as it remained his least used pitch. In 2022, however, he’s now using it 19.5% of the time, slightly more than he uses his super effective changeup.
Something to consider here is that Iglesias’ sinker and changeup are his most effective pitches at generating ground balls. In 2022, he currently owns the worst groundball rate of his career at just 29.4% due to his sinker losing even more effectiveness and using his changeup less. Keep this in mind for later.
Moving on to Iglesias’ slider, this pitch is currently the epitome of boom or bust. Unlike his sinker, the slider is typically his best pitch and, at first glance, 2022 doesn’t seem much different in that regard. With batters hitting just .214 against it, Iglesias’ slider is currently generating the second highest whiff rate of any pitch in any season of his career at a whopping 50.0%.
The problem, however, is that when batters actually do make contact with it, they are absolutely crushing it. From 2015-2021, batters never slugged higher than .366 against Iglesias’ slider. In 2022 they are slugging .714 against it.
Ignoring Iglesias’ 2015 rookie season when he was primarily a starter, at no point over the next six seasons did batters ever hit more than two home runs or two doubles off his slider. Excluding the shortened 2020 season, Baseball Savant shows that in that span he threw anywhere from 303-396 sliders each season in around 70 total innings each year.
So far in 2022, having thrown just 93 sliders across 21.1 innings, Iglesias has already surrendered two home runs and one double. If we assume he ends the year throwing roughly 370 sliders in total, Iglesias’ current pace has him allowing at least eight home runs and four doubles on just his slider this season. Unsurprisingly, the average exit velocity against his slider this year is the highest it’s ever been at 88.2 mph (in 2021 it was 82.1 mph).
This new development is the main reason why Iglesias is currently putting up the highest fly ball rate (47.1%), hard hit rate (38.5%), barrel rate (13.5%), HR/9 (2.11), and HR/FB ratio (20.8%) of his entire career, and all by wide margins. The result is that of the 52 balls put in play against Iglesias this season, nine (17.3%) have been for extra base hits (five home runs, four doubles).
Now, consider Iglesias’ increased fly ball rate and decreased groundball rate together and recall how low his SIERA and xFIP are compared to his ERA. This all culminates to reveal the potential source of all his bad luck this year.

The LA Angels have a massive problem with their outfield, so much so that it is starting to have a serious impact on how pitchers like Raisel Iglesias perform.
With a better outfield defense from the LA Angels, Raisel Iglesias would be performing much better in 2022.
In a year when the LA Angels finally have a good infield defense, Raisel Iglesias just so happens to be allowing the lowest groundball rate and the highest fly ball rate of his career.
On one hand, Brandon Marsh has been fantastic defensively and Mike Trout is having one of his best defensive seasons in years. On the other hand, Jo Adell, Taylor Ward, Juan Lagares, and all of the infielders that have been thrown into the outfield have mostly been awful.
According to Fangraphs, Marsh and Trout combine for 854 innings, six DRS, 0.6 UZR and 6.4 UZR/150. Everyone else who has played in the outfield for the Angels combines for 792 innings, -5 DRS, -9.7 UZR, and -95.1 UZR/150.
While allowing home runs still falls squarely on Iglesias’ shoulders, the extra men getting on base and outfield miscues are mostly out of his control. For a prime example of this, look no further than in the Angels 6-5 win at the White Sox on May 1.
Though the Angels managed to stop the White Sox one run short in their five-run ninth inning rally, Iglesias was tagged for two runs and was taken out early. Looking beyond the stat sheet, however, shows that the first run was almost entirely Adell’s fault.
With a man on second, Iglesias got Josh Harrison to hit a weak fly ball to shallow left field that Adell completely misread, causing him to stumble at the jump and fail to make the diving catch, ultimately allowing the ball to get past him to give Harrison the RBI double and prolong the inning. Oh, and the pitch that Harrison hit, it was a pretty decent slider a few inches off the plate.
If Adell makes what should have been a routine play, that’s out number three, meaning two less earned runs and one less double for Iglesias, as well as one less XBH against his slider.
While not every run or hit against Iglesias can be blamed on the defense, the fact that there are examples as egregious as this show clear evidence of just how unlucky he’s been this year. He may not be as sharp overall this season compared to 2021, but he isn’t anywhere near as bad as his ERA makes him out to look.

In the end there’s still a lot of season left to play and Iglesias should figure to pitch at least another 50 innings. Who knows, maybe his luck will finally begin to turn.
