Forecasting a High‑Scoring Day in the Majors
Major league baseball analysts are converging on a slate of games slated for June 23 that could see more runs than usual, with several matchups projected to exceed the 8.5‑run over/under threshold.
Among the most talked‑about contests is the Philadelphia Phillies’ showdown with right‑hander Zack Littell, a game that Josh Inglis expects the Phillies to win by multiple runs.
Neil Parker, another forecaster, leans toward the Seattle Mariners defeating the Pittsburgh Pirates in a high‑scoring affair, predicting the total will climb past 8.5 runs.
Joe Osborne adds the Oakland Athletics versus the San Francisco Giants to the same over‑8.5‑run category, citing recent offensive trends.
Littell’s home‑field numbers add intrigue: a 6.31 ERA at home and a recent start where he surrendered seven runs, while left‑handed batters have already knocked out 16 homers against him with an OPS above 1.000.
On the mound, Jesus Luzardo has been unusually steady, posting two‑run or fewer outings in six of his last seven starts.
Meanwhile, George Kirby’s 6.27 ERA and 4.80 xERA, coupled with a 44.4% hard‑hit rate over his past six starts, suggest vulnerability, a point underscored by Mitch Keller’s 7.64 ERA, 6.33 xERA and 42.6% hard‑hit rate across his last seven outings.
Seattle’s xwOBA ranks 11th over the past month, while Pittsburgh sits seventh, indicating both teams have been generating quality contact.
Aaron Civale’s recent stretch includes 18 earned runs over his last three starts, a stretch that could influence betting lines.
The Giants, sitting 10th in OPS over the last two weeks, present a potent lineup that could test any pitcher they face.
Robbie Ray’s inconsistency this season meets an Athletics roster that has historically crushed left‑handed pitching, adding another layer of uncertainty.
