Grissom is a hold — league average, and the bat is drifting down.

His expected wOBA is .309 against a league average of .315, and with 474 plate appearances he has cleared the sample needed to trust it. His actual wOBA is .306, so the line and the skill agree — no luck is inflating or hiding anything. The contact quality is ordinary: 87.5 mph average exit velocity against 89.0, a 35.6% hard-hit rate against 40.0%, and 6.7% barrels against 8.0%, all on 343 batted balls. He strikes out less than league at 18.4% and walks less at 6.5%, roughly offsetting. The one thing worth watching is direction: that expected wOBA has been stepping down across the sample. Nothing here is broken and nothing is unstable, but the bat is not gaining either. Hold. A 0 HR / 0 R / 0 RBI / 0 SB / .000 AVG line makes him waiver-wire filler — a drop-tier fringe bat, not an asset.
