Rodriguez is a sell-high — ERA is a mirage, xERA says sell.

His ERA is 2.29, but that number is being driven by a BABIP-against of .248, which is 47 points below league average. BABIP-against needs around 800 balls in play to be reliable; he has 344, so that gap is luck, not skill. His expected ERA is 5.06 — nearly 2.8 runs higher than his actual ERA — and that gap has been stepping up across the sample. The underlying metrics confirm the skill is below average: he allows a 9.6% barrel rate (above the 8.0% league average) and strikes out only 17.1% of batters (22% league average). There is no elite-stuff story here. The ERA is the luckiest number on the card. Sell high. 48 K and a 4.72 ERA: treat as a streaming-only asset in shallower formats. The trade window is open.
