Rodriguez is a sell-high — the 2.55 ERA is a BABIP mirage.

His ERA sits at 2.55, but the number underneath tells a different story. His BABIP-against is .269, twenty-six points below the league average of .295, and BABIP-against needs around 800 balls in play to become reliable. He has 524, so that suppression is not something to trust. His expected ERA is 4.32 — 1.77 runs above the surface — and it has been stepping up across the sample, which is the wrong direction. His strikeout rate is 18%, four points below league, and his fastball averages 92 mph, two ticks below average. The contact he allows is ordinary. The low ERA is a number on a scoreboard, not a skill. Sell high. Regression to a 4.24 ERA, 1.32 WHIP and just 10 K ROS makes this a drag — stream, don't hold.
