Bo Bichette's June Experiment Was Weird and Successful and Maybe Not Sustainable

Bo Bichette went from problem to solution in one month. In May, he hit .207. In June, .321. His OPS jumped from .576 to .883. He did it while posting baseball's highest chase rate (44.8% O-Swing%). The question: Is an aggressive, contact-oriented approach the optimal strategy for a hitter with Bichette's exceptional bat-to-ball skills?

Bichette has always been aggressive. His career O-Swing% sits at 37.1%, well above the league average. But he's made a career on turning difficult pitches into quality contact at a rate few hitters can match.

His career O-Contact% has remained above league average. For much of his career, he has ranked among the best qualified hitters in baseball in that category. A hitter can be aggressive without sacrificing plate discipline. At his best—most notably during his 2025 season, when he posted a 134 wRC+—Bichette paired aggression with selectivity. He chased pitches, but his O-Swing% was 35.2%. When he chased, he made contact.

To understand why this strategy works, look at how Bichette changed from month to month.

Month	O-Swing%	O-Contact%	Z-Swing%	Z-Contact%	Swing%	Contact%	K%	BB%
Mar/Apr	40.9%	72.4%	69.7%	90.4%	54.7%	83.4%	19.9%	5.9%
May	35.4%	79.8%	66.8%	94.3%	50.2%	88.9%	12.3%	9.0%
June	44.8%	56.6%	68.6%	90.7%	55.7%	75.9%	23.9%	2.6%

In May, Bichette found the sweet spot. He chased less and made more contact when he did. His strikeout rate dropped to 12.3%, while his walk rate climbed to 9.0%. It was the version of Bichette that had made him so productive in previous seasons: aggressive, but controlled. Then, June arrived. His O-Swing% jumped 9.4 percentage points. His O-Contact% collapsed by more than 23 points. He went from missing two out of every ten swings at pitches outside the zone to missing more than four. His strikeout rate nearly doubled, while his walk rate fell to less than one-third of its May level.

Yet his production improved. His ISO rose from .090 to .220. His slugging percentage jumped from .297 to .541. He hit five home runs in June after hitting only three in May.

Month	Blast Contact%	Squared-Up Contact%	Barrel/BBE%	Attack Angle	Ideal Attack Angle%	HardHit%	EV
May	14.1%	31.6%	11.5%	2°	24.0%	42.7%	90.4
June	17.0%	35.2%	6.0%	4°	31.1%	43.4%	91.2

Blast Contact and Squared-Up Contact describe how well the ball was struck when contact occurred. Barrel/BBE measures how often batted balls reached the specific combination of exit velocity and launch angle that Statcast classifies as barrels. In June, Bichette improved both his Blast Contact and Squared-Up Contact rates. When he made contact, he hit the ball harder and found the sweet spot more often.

The problem was that he made contact far less often. His Whiff% jumped from 11.6% to 26.8%. While some indicators of contact quality improved, that improvement did not translate into a higher barrel rate. His Barrel/BBE fell from 11.5% to 6.0%, suggesting that the gains in contact quality were neither uniform nor complete across the various dimensions measured by Statcast. There was also a change in his batted-ball profile. His average Attack Angle increased from 2 degrees to 4 degrees, while his Ideal Attack Angle% climbed from 24.0% to 31.1%. He elevated the ball, helping explain the power surge.

That adjustment was real, but it came with a broader deterioration in the rest of his offensive profile. His ability to put the ball in play declined. His strikeouts increased. His walks disappeared. The improvements in certain contact-quality metrics arrived alongside a decline in the underlying process. His .380 BABIP, well above his career mark of .334, points to good fortune. His .299 expected batting average versus an actual .321 average indicates that the quality of contact justified much of the production, but not all.

Which brings us back to the original question. What June demonstrated is that Bichette has a larger margin for error than most hitters. His bat-to-ball ability gives him that margin. Few hitters could survive that process for a month and still produce. But surviving is not the same thing as sustaining. For one month, Bichette drifted toward a three-outcome profile: more strikeouts, few walks, and damage whenever he managed to make contact. That is not the profile on which he built his career, nor the profile that best leverages his greatest strength.

The evidence points to one conclusion: an aggressive approach can work for Bichette, but only as long as aggression doesn't become an unchecked chasing habit.

Bichette had to do something to shake himself out of the rut he was in.  I think he'll work his way back to his normal approach, but getting more aggressive served its purpose.
