Alvarado is a sell-high — his ERA is running on borrowed luck.

His ERA is 3.90, but the number holding it down is his BABIP-against: .268, well below the league average of .295. BABIP-against needs around 800 balls in play to be reliable, and he has 137. That gap is luck, not skill. His expected ERA is 4.42 — half a run above what the box score shows — and it has been climbing as the sample grows. The contact allowed backs that up: 46.7% hard-hit and 13.1% barrels, both well above league, on a sample past the point where those numbers become reliable. He misses bats at 28.4%, so the stuff is real, but the walks sit at 10.9% and the contact quality is poor. The scoreboard is ahead of the skill. Sell high. The 4.17 ERA / 1.30 WHIP ROS line is barely rosterable — cash the inflated line in, a drop-tier tax otherwise.
