For clarity purposes, I would like to set the record straight on what defines a “breakout player”. At least the way I see it, a breakout player is not someone who was a blue chip prospect and is following his expected trajectory in the form of a star level ascension in his second year. Specifically, the player can never have been a consensus top 10 prospect at any point or posted 2.5 fWAR season in their career. A breakout player does not have to play at a superstar level, rather they need to merely be a productive player because to be on this list in the first place you can’t have had a massively productive season in the past.
1. Lenyn Sosa, Chicago White Sox
I do not expect there to be an overwhelming number of bright spots for this Chicago White Sox team. Coming off of a historically pitiful season, the White Sox faithful will be looking to cling on to any bright spot they can get and I think they are in for pleasant surprise with Lenyn Sosa. On the surface, Sosa has not shown much promise, posting a 0.1 fWAR, 80 wRC+ season in 2024. When you look deeper though, you see that Lenyn Sosa could be a diamond in the rough. Sosa’s peripherals are intriguing, he batted .254, but his expected batting average was .278, his OBP was a minuscule .283 but his xwOBA was a respectable .316, and his xSLG is also 69 points higher than his actual slugging percentage. From a batted ball perspective, he utilizes launch angles as well as anyone, posting a 99th percentile sweet spot rate. He also has a solid hit tool, posting a sub 20% whiff rate and an above average strikeout rate. I do wish he was a bit more selective as he swings at an obscenely high percentage of his pitches, leading to a 3.3% walk rate. Sosa actually has a very underrated bat and I believe the ball just did not bounce his way in 2024, look for that to change in 2025.
2. Michael Toglia, Colorado Rockies
Michael Toglia can flat out hit, no if and’s or buts. In 2024, UCLA product posted a .767 OPS with 25 Homers, notably also swiping 10 bags in the process. The Coors tax is real though, as his seemingly solid .767 OPS translated to a 98 wRC+, meaning he was technically a below average hitter. This along with the marginal value he provides defensively, led him to a negligible fWAR total of 0.4 in 116 Games. With his peripherals, I struggle to see a way that total doesn’t multiply. He posted a .358 xwOBA(90th pct.) and a .503 xSLG(93rd pct.). This stems from the fact that he hits the seams off the ball, posting a 92.1 Average Exit Velocity(91st pct.). His ability to generate barrels also makes him a spectacular fit for Coors Field, his 98th percentile Barrel Rate comes from the fact that 50.2% of his batted balls come in at 95+ MPH, the real kicker is the 39.2% Sweet Spot Rate. With Toglia, you take a 30+% K% because you know he will reciprocate with comfortable double digit walk rate. Toglia’s analytical profile has checks every box for a corner infield masher.
3. Alek Thomas, Arizona Diamondbacks
Coming into the big leagues, it was expected that Alek Thomas and Corbin Carroll would spearhead the Diamondbacks’ outfield. To this point, Carroll has certainly held up his end of the bargain but Alek Thomas has left a bit to be desired. Many are out on Alek Thomas, but I believe we are about to see him fulfill the prophecy. Due to surface level under performance and injury, we only saw 95 ABs from Thomas in 2024, in which he posted a measly .603 OPS. Although it may not seem like it, Thomas actually took strides offensively. He posted a 47% Hard Hit Rate and a 91.2 Average Exit Velocity, both of which are in the upper echelon. This led him to a .278 xBA and a .446 xSLG, both of which were leaps and bounds above their baseline counterparts.
4. Christopher Morel, Tampa Bay Rays
Out of any of the 5 players on this list, Christopher Morel is the player I’m most confident in to breakout. Morel has always had the tools, even back in Chi town, Morel could hit the piss out of the baseball, fly around the bases, and throw the seams off the ball. He is yet to put it together though, in 2024, he hit below the Mendoza line and posted a .634 OPS. I still have faith that Morel can be a productive hitter and he feels like a classic case of the Rays working their magic and helping him to connect the dots. He posted a 69th percentile Barrel Rate and a 10% Walk Rate, he clearly has potential. The weirdest part of his profile though is that he is anemic defensively, I don’t expect this to continue though. He has a cannon for an arm and his a great athlete, he has mechanical issues yes but who better to smooth those kinks out than Tampa.
5. Maikel Garcia, Kansas City Royals
This time last year, Maikel Garcia was probably the most popular breakout pick in analytical circles. However, a calendar year later it seems like everyone is has given up on him. Not me though, looking at Garcia’s analytical profile, I still see loads of potential. On the surface, Garcia did not hit well in 2024, posting a .613 OPS with just 7 homers. When you look deeper though, you see the same thing that excited so many people last winter. The 2 metrics that create the stat Barrel Rate, are Hard Hit Rate and Sweet Spot Rate. Garcia is solid in both of those metrics, posting a 65th percentile HH% and a 48th percentile SS%. Based on that, conventional wisdom would tell you that he would post at least an average Barrel Rate, but nope, he posted a 10th Percentile Barrel rate. That is statistically impossible and there is almost no way that holds true. He is also a very well rounded hitter, posting minimal whiff rates and taking his walks. On top of that, Garcia provides elite speed and defense stealing 37 bags and posting a 76th percentile OAA, meaning if he is even an average hitter, he could be a 4 win player.
