Wrobleski is a sell-high — his ERA is running on borrowed time.

His ERA is 3.66, but the metrics underneath say the real number is closer to 4.54, and the xERA has been climbing as the sample has grown. The stat holding that ERA down is his BABIP-against at .269, against a league average of .295. BABIP-against needs around 800 balls in play to be reliable and he has 424, so that gap is luck, not a skill he owns. Nothing in his profile gives the low BABIP a reason to stick: he strikes out 20.4% of batters, below league average, and his swinging-strike rate is 10.3%, also below league. His expected wOBA allowed is .326 against .315 league average, and his hard-hit rate allowed is 43.9%. The contact he allows says the ERA will catch up to the xERA. Sell high. Sell into a 4.39 ERA / 1.20 WHIP line before it climbs — deep-league owners have a trade window, not a hold.
