Josh Bell stepped up to the plate twice against Houston on Monday night and sent the ball flying over the fence both times. Despite his heroics, the Twins lost 6-3, making the numbers even more puzzling. Before May 18th, Bell had only five home runs in 45 games — a slow start, not a power surge. Then, in just one evening, he almost doubled that total. Statistically, what happened at Target Field on Monday was nearly impossible.
Home runs are rare in baseball's daily games. On May 18th, the average player hit just 0.14 home runs per game, meaning most players didn't hit any at all. Bell hit two. This jump from 0.14 to 2 resulted in a z-score of 5.15 compared to every player who played that day. To put that in perspective, a z-score above 4.0 is a performance you'd expect to see across the entire league only once every few seasons. At 5.15, Bell's performance was off the charts. Even if you looked at every game played by every player over a full 162-game season, you'd find very few performances this extraordinary.
We can't analyze the mechanics of Bell's home runs because there's no data on exit velocity or launch angle from this game. However, we can look at Bell's season stats before this game. He was hitting .223 with a .361 slugging percentage and a .647 OPS, indicating he was making contact but not hitting the ball with much power. There are three possible reasons for his two-homer night: Houston's pitchers gave him pitches he could hit well, Bell made some changes to his swing that paid off, or it was just one of those random outlier performances. Without detailed pitch data, we're left guessing based on probabilities.

Bell is 33 years old with a career spanning 1,332 games and 198 home runs — averaging one homer every 6.7 games, which makes him a consistent but not prolific power hitter. His five home runs in 45 games before Monday were slightly below his usual pace. The two-homer game brings his total to seven and could be a turning point, depending on what happens next. The irony is in the final score: 6-3, Astros. Bell provided nearly all of the Twins' offense, but it wasn't enough. Two home runs in a losing effort tend to be overlooked, but the stats tell a different story.
Keep an eye on Bell's slugging percentage over his next 10 games. He started Monday at .361. If it rises above .420 by June 1st, something significant has changed — perhaps in his pitch recognition, swing mechanics, or coaching adjustments. If it falls back to the .350-.370 range, Monday's performance might just be a fluke. As a switch hitter, it would also be interesting to see which side of the plate he hit those home runs from against Houston. If they came from the left side against right-handed pitching, it could narrow down the mechanical reasons. The Twins' next series will start to reveal the answers.
A z-score of 5.15 is the kind of statistic that makes you double-check your numbers. Bell achieved it in a game his team lost — which is either quintessentially baseball or the start of something the Twins haven't yet capitalized on.
