Vientos is a hold — average skill, average results, nothing moving.

His expected wOBA is .304, within .011 of the league average of .315, and he has 295 plate appearances — well past the 160 needed for that number to be reliable. The actual wOBA of .283 sits a bit lower, but his expected figure is the one to trust, and it points at a league-average bat. His contact quality is slightly above the line and stable: 89.8 mph average exit velocity, a 43.7% hard-hit rate, and 9.7% barrels, each a touch over league. The one thing tilting the wrong way is his expected wOBA, which has stepped down across the sample. That is not a collapse, just a leveling off. A 5.1% walk rate against a 24.1% strikeout rate limits the on-base floor. There is no unstable stat inflating or deflating this line. Hold. A 0 HR / 0 R / 0 RBI / 0 SB / .000 AVG line means streaming-only; hold the real 1B, not this placeholder.
