Robert Gasser
Gasser is a sell-high — his ERA is riding suppressed BABIP
His BABIP-against is .268, 27 points under the league average of .295, and that gap is the whole reason his ERA reads 3.87. BABIP-against needs around 800 balls in play to become reliable, and he has 315 — luck still drives this stat at his sample. The luck-free expected ERA is 4.27, .40 above the number on the scoreboard, and it has been stepping up across the sample. Nothing underneath points to a run-prevention leap: his xwOBA allowed of .317 sits right on the .315 league mark, his strikeout rate of 22.3% and walk rate of 7.4% are league-average, and his fastball averages 92.9 mph against a 94.0 league average. This is an average pitcher wearing a good ERA. Sell high. The 0 K / 4.21 ERA / 1.26 WHIP ROS line confirms the sell — a drop-tier arm, streaming-only, with the trade window shut.
