Randy Arozarena's Resurgence

With the postseason quickly approaching, it is never too early to start looking ahead at the upcoming free-agent class. In what appears to be a fairly light group of unrestricted free agents, Mariners outfielder Randy Arozarena has worked his way back into the conversation as a significant offensive acquisition. 

Arozarena is putting together one of the best seasons of his career outside of his incredible 2020 season, where he went on to hit .377 with 10 home runs in the postseason earning ALCS MVP honors. He has now eclipsed 20 home runs and 20 stolen bases for the 6th straight season, becoming just 1 of 5 players in MLB history to accomplish the feat. 

With only a handful of games remaining, his .279 AVG, .481 SLG, and .857 OPS all rank as the 2nd-highest in his career, excluding 2019, when he logged just 20 at-bats. While ranking 10th in the AL in SLG, he has hit the 2nd-most home runs in the AL since the All-Star break and his 150 wRC+ ranks 4th highest in MLB. Among qualified hitters, Arozarena also owns the 9th-largest increase in batting average from 2025 to 2026 and the 6th-largest decrease in strikeout rate. 

That production becomes even more impressive considering he plays his home games at T-Mobile Park, which Statcast rates as the most difficult park for both right-handed batters and hitters overall. It has also come despite career lows in average bat speed and fast-swing rate, with his bat speed down roughly 2 mph from his career norm while his average exit velocity has remained in line with his typical levels. 

Several areas stand out when looking at what may be driving the improvement: his production around and outside the strike zone, his performance with 2 strikes, and his success against breaking and offspeed pitches. 

Shadow and Chase Zones

Arozarena has been significantly better around the edges of the strike zone this season. 

Shadow Zone

2019-2025 → 2026

AVG: .239 → .298

wOBA: .304 → .351

K%: 28.8% → 21.9%

His .298 AVG ranks 4th in the AL and 14th in MLB, while his .351 wOBA ranks 7th in the AL and 13th in MLB among hitters with at least 150 plate appearances ending in the Shadow Zone. His strikeout rate is also the lowest of his career 

The gains become even more pronounced on pitches farther outside the zone.

Chase Zone

2019-2025 → 2026

wOBA: .348 → .403

xwOBA: .340 → .429

Whiff%: 54.0% → 38.9%

K%: 33.0% → 25.5%

His .429 xwOBA is a career high and ranks 6th in the AL and 10th in MLB among hitters with at least 50 plate appearances ending in the Chase Zone. The biggest change is the contact improvement, with his whiff rate dropping nearly 15 percentage points from his prior career norm.

2-Strike Performance

Arozarena has also become much more difficult to put away once pitchers get him to 2 strikes. 

2019-2025 → 2026

OBP: .272 → .294

SLG: .281 → .321

wOBA: .253 → .281

Whiff%: 27.3% → 21.5%

K%: 44.4% → 36.3%

His OBP, SLG and wOBA are all his best marks since 2020, while his whiff and strikeout rates are both career lows. All 5 measures are also better than the 2026 league average

Non-Fastballs

The improvement against breaking and offspeed pitches has been substantial.

2019-2025 → 2026

.228/.288/.383/.671 → .270/.327/.477/.804

That represents a 42-point increase in AVG, 39-point increase in OBP, 94-point increase in SLG and 133-point increase in OPS.

Among qualified hitters, his .270 AVG ranks 14th in MLB and 7th in the AL, his .477 SLG ranks 13th in MLB and 8th in the AL, and his .804 OPS ranks 9th in MLB and 5th in the AL. 

Breaking Balls

2019-2025 → 2026

Swing%: 44.3% → 49.2%

AVG: .228 → .268

SLG: .392 → .495

OPS: .677 → .814

Whiff%: 34.3% → 26.7%

K%: 30.0% → 23.3%

His AVG, SLG, OPS and wOBA are all career highs against breaking balls. His .268 AVG ranks 13th in the AL, while his .495 SLG ranks 10th in the AL.

The most notable part is that the added aggression has not created more swing-and-miss. He is swinging more often while whiffing and striking out at career-low rates. 

Offspeed Pitches

2019-2025 → 2026

Swing%: 45.8% → 48.2%

SLG: .360 → .437

OPS: .656 → .781

wOBA: .289 → .345

Whiff%: 34.7% → 22.9%

K%: 30.0% → 18.8%

His SLG, OPS and wOBA are all the 2nd-best marks of his career. More importantly, his whiff and strikeout rates are both career lows and well below league average. 

Arozarena is having one of the most under appreciated seasons in MLB this season and his overall profile looks a lot stronger than it ever has, setting a career high in fWAR. He is making more contact, striking out less and producing in areas where he has historically been much more vunerable. He is doing this while still providing the power and baserunning value that have long been important parts of his game.

The biggest takeaway is not just that the results have improved, but that the way he is getting to those results has changed as well. He has become harder to putaway, more productive against secondary pitches and more consistent in difficult hitting situations. If teams belive even most of these gains are real, Arozarena should enter a fairly thin free-agent class as one of the more interesting offensive options on the market this winter.
