Miami Marlins third baseman Otto Lopez has posted the largest batting average improvement in all of Major League Baseball this season, vaulting him into All-Star consideration and a potential National League batting title race. After struggling with a .246 average and career-low offensive production in 2023, Lopez has revamped his swing under hitting coach Pedro Guerrero, increasing his average by .088 points—a figure that has MLB analysts and fans taking notice.
Lopez’s transformation comes after a turbulent offseason that saw him move through three teams in less than three months. The Quebec native was designated for assignment by the Toronto Blue Jays in February 2024, traded to the San Francisco Giants four days later, and then claimed off waivers by the Miami Marlins on April 4 of that year. Now, two seasons after his release by the Giants following just two months with the team, Lopez is on track to deliver one of the most dramatic offensive resurgences in recent memory.
According to MLB.com’s batting leaderboards, Lopez leads all qualified hitters in year-over-year batting average improvement, a distinction that has placed him in conversations about the National League’s batting crown. His .334 average through June 2024 would rank him among the league’s top hitters if sustained, and scouts credit his newfound power and plate discipline to a disciplined approach developed over winter.

How Otto Lopez Went From Struggling Hitter to MLB’s Most Improved Player
Lopez’s turnaround began with a complete overhaul of his swing mechanics. After posting a career OPS+ of just 91—a figure well below league average—over more than 1,000 plate appearances, the 27-year-old worked with Guerrero, a former MLB All-Star and hitting coach with decades of experience, to refine his approach. The focus was on generating more bat speed, shifting his weight forward, and using his legs more effectively to drive into pitches.
According to Fangraphs, these adjustments have paid off dramatically. Lopez’s ground-ball rate has decreased, allowing more balls to drop in for hits rather than being turned into outs. His power numbers against fastballs have surged, and his improved contact rate has made him a far more dangerous hitter than the player who batted .246 in 2023.
The changes are evident in the numbers. Through June 2024, Lopez is hitting .334 with a .900 OPS, figures that would place him among the NL’s elite hitters if maintained. His slugging percentage has risen by nearly 50 points compared to last season, and his walk rate has improved significantly, reducing his strikeout-to-walk ratio—a key indicator of plate discipline.
Who Else Is Leading the Charge in MLB’s Most Improved Hitters?
Lopez isn’t the only player making a dramatic offensive resurgence in 2024. According to Baseball-Reference, the top three hitters in year-over-year batting average improvement are:
- Otto Lopez (Marlins) – .088 increase (.246 in 2023 to .334 in 2024)
- Jordan Walker (Cardinals) – .079 increase (.253 to .332)
- Oneil Cruz (Pirates) – .075 increase (.261 to .336)
While Cruz currently leads the NL in batting average, Lopez’s combination of power and contact improvements has made him the most likely candidate to sustain his success over the remainder of the season. The Marlins’ third baseman is now a daily threat to post multi-hit games, a rarity during his early career.
Why This Matters: The Science Behind Lopez’s Swing Adjustments
Lopez’s transformation isn’t just about raw talent—it’s the result of meticulous mechanical adjustments. Guerrero’s philosophy, which emphasizes weight transfer and leg drive, aligns with modern hitting theories that prioritize quick hands and aggressive contact rather than pure swing strength.
According to MLB.com’s analysis, Guerrero has worked with Lopez to eliminate “casting” (where the hands lead the bat, reducing power) and instead focus on a “launch angle” approach that maximizes exit velocity. The results speak for themselves: Lopez’s average ground-ball exit velocity has increased by nearly 5 mph, a figure that correlates directly with his improved batting average.
For context, a 5 mph increase in exit velocity can translate to roughly a .050 increase in batting average, according to Fangraphs’ exit velocity studies. Lopez’s .088 improvement suggests his adjustments have gone beyond mechanical tweaks to a fundamental shift in how he approaches pitches.
What Happens Next: All-Star Consideration and Batting Title Implications
With the All-Star Game fast approaching, Lopez’s name is already circulating among fan voting and manager ballots. His .334 average would rank him among the top NL hitters, and his power-speed combination makes him a viable candidate for the batting title if he maintains his pace.
The Marlins’ third baseman is also a dark horse candidate for the NL’s Most Improved Player award, a distinction that would cap off an incredible turnaround. If he continues his current trajectory, Lopez could finish the season with a batting average above .350—a figure that would place him in the conversation for NL MVP consideration, particularly if his power numbers continue to climb.
For now, the focus remains on consistency. While Lopez has shown flashes of elite hitting, sustaining his production over the final three months of the season will determine whether his 2024 resurgence is a fleeting hot streak or the beginning of a new career chapter.
Key Takeaways: Lopez’s Journey in Numbers
