Trent Grisham

A Practical Look at Trent Grisham

Trent Grisham is a right-handed hitting, left-fielding outfielder currently under contract with the San Diego Padres. He was originally drafted by the Milwaukee Brewers in the first round of the 2017 MLB Draft out of Foothill High School in California. The Padres acquired him in the Corey Lusonye trade that sent him from Milwaukee to San Diego before the 2021 season. He has spent time at left field, center field, and first base over the course of his career. Grisham's primary value has always been his glove. He won the Gold Glove Award in 2022 while playing center field for the Padres, recording 14 defensive runs saved and 6 outs above average that season according to Statcast measurements. His range in center is legitimate, and he reads balls off the bat quickly enough to cover a substantial area. In left field, he's serviceable but not as impactful defensively since the position doesn't demand the same vertical range. Where things get complicated is the batting side of the ball. Grisham has never been a consistent run-producer at the plate. His career batting average hovers around .218, and his strikeout rate typically sits in the low-to-mid 20s percentage range. The counter-intuitive thing about him is that his low average actually understates his offensive profile slightly. He possesses a decent walk rate, usually between 9 and 11 percent, and he generates enough isolated power to post an OPS that often lands in the .700s despite the contact issues. This is the kind of offensive output you'd normally expect from a utility corner INF, not a starting center fielder.

I've tracked Grisham's batted ball data closely over the last three seasons, and one thing that stands out to me is his ground ball tendency. He's a career 50-plus percent ground ball hitter, which is extreme for a guy listed at 6-foot-1. This dramatically caps his home run upside and makes his hit tool the variable that determines whether he's even a below-average offensive contributor. When he keeps the ball in the air, his power numbers are respectable. When he stays on the ground, you're looking at singles and weak contact most of the time.

How to Track or Evaluate Grisham for Fantasy or Betting Purposes

If you're trying to use Grisham in fantasy baseball or sports betting contexts, the most practical approach is to monitor his batted ball profile rather than looking at raw batting average. The raw average will lie to you because it fluctuates wildly on low-volume contact hitters. Instead, watch his barrel rate and hard-contact percentage week to week. When those metrics are above league average, Grisham becomes a viable OF corner piece in deep leagues. When they drop below 15th percentile, he's mostly a bench player even in 12-team mixed leagues. His 2023 season is a good case study. He hit just .207 with 17 home runs and 58 RBI across 120 games. The home run total was a career high, but his batting average dropped even further than usual. Most fantasy managers who held onto him through that entire season were frustrated by the floor collapse, even though the power numbers were actually solid. This is the pattern you keep running into with him. The profile is jagged. One specific problem I've encountered when managing fantasy rosters with Grisham is his platoon splits. He's a left-handed batter facing right-handed pitching for the vast majority of his at-bats, and historically his numbers against righties are only marginally better than against lefties. This makes him nearly unrotable in daily fantasy sports on any given night where he's not in a favorable matchup. I stopped trying to start him against top-tier right-handed starters after losing money on three straight occasions in 2023. The workaround was simple: I only slot him in when he's facing a left-handed reliever late in a game or when he's in a pitcher-friendly park like Oracle Park with a questionable home starter. Even then, his ceiling is moderate at best.

The real downside to investing time in Grisham is his inconsistency. He's prone to long slumps that can last three to four weeks without warning. There's no reliable indicator ahead of time that a slump is coming other than a visible drop in exit velocity, and by the time you notice that on Statcast, you've already been living with the bad production for a week. If you're managing a fantasy roster, the pragmatic move is to hold him during hot streaks and stash him on the bench or IL during cold stretches rather than dropping him entirely, since his power floor keeps him relevant enough to be useful again quickly. For betting purposes, Grisham's underlying metrics suggest he's more of a buy-low candidate after a rough stretch than a sell-high candidate during a hot week. His expected batting average based on batted ball quality has consistently outperformed his actual batting average, which means positive regression is often coming. That said, regression can take weeks to materialize, so this isn't a quick fix strategy. It's a longer-term hold approach.
