Webb is a hold — league-average skill, nothing swinging the line.

His expected ERA is 4.35, close enough to the league average of 4.10 that the number comes out level. The rare part is the strikeout rate: 25.7% of batters, well above the 22% league mark, and his swinging-strike rate sits at 16.6% against 11%. That is swing-and-miss stuff that the surface line does not fully cash in. The problem is the contact he allows when batters do make contact — a .320 expected wOBA allowed and a 41.6% hard-hit rate allowed, both a touch worse than league. His xERA has been stepping up across the sample, so the recent shape leans the wrong way. A strikeout arm with average run prevention is a useful pitcher and not a special one. Hold.
