Oakland Athletics vs Cleveland Guardians Predictions: Jack Perkins vs Gavin Williams

Game time: September 20, 2026 at 1:40 PM ET

Venue: Progressive Field — Cleveland, Ohio

Article updated Sep 20, 12:05 AM EDT

By SportsJaw Editorial Team

Gavin Williams brings the stronger season profile, while Jack Perkins' latest start offers counterevidence. Neither the side nor the total clears the bar for a recommendation.

The pitching comparison favors Cleveland

The Athletics visit the Cleveland Guardians at Progressive Field on September 20, 2026, in this MLB matchup. MLB.com and Covers identify right-handers Jack Perkins and Gavin Williams as the probable starters.

Williams has a 3.78 ERA and 235 strikeouts, compared with Perkins' 6.14 ERA and 127 strikeouts. Williams also delivered two strong September outings: seven innings with one run, no earned runs and 13 strikeouts against Toronto on September 1, then six innings with two earned runs and 11 strikeouts at Detroit on September 6.

Perkins supplies a reason to temper that advantage. At Tampa Bay on September 15, he allowed four hits and one unearned run over 6 2/3 innings, striking out eight and walking one. His five-start ERA of 5.11 remains higher than Williams' 3.96 over his listed five-start window, but that latest performance cautions against assuming an easy Cleveland win.

Team results reinforce the edge, with limits

Covers lists Cleveland's relievers with a 3.57 ERA against Oakland's 5.34. Those season figures favor Cleveland, although they do not establish which relievers are available for this game.

Oakland is 3-7 over its last 10 games and lost 5-3 and 12-6 at Cleveland on September 18 and 19. Those results support Cleveland's recent form, but two games provide limited grounds for projecting Sunday's scoring.

The prices leave unanswered questions

SportsJaw lists Cleveland at -233 moneyline and Oakland at +200. Cleveland's pitching advantage is supported; whether it is large enough to justify that favorite's price is less certain. The Guardians' -1.5 run line (+100) also requires a winning margin the available numbers do not reliably establish.

The total is 7.5, with over at +105 and under at -125. Williams' stronger run prevention and Oakland's higher bullpen ERA pull the scoring case in different directions. Without confirmed lineups, relevant offensive splits or bullpen availability, neither direction earns a recommendation. The selection is Pass, with no projected winner or score.
