Guardians vs. Athletics Prediction, Winner Payout, Over/Under – Sunday, May 3
To conclude the three-game series, it will be the Guardians SP Parker Messick (2.98 xFIP across 6 starts and 36.1 IP) and the Athletics SP Aaron Civale (4.51 xFIP across 6 starts and 30.2 IP) squaring off on the mound.
Messick has been a major bright spot for the Guardians in the early going this season, residing in the 87th percentile in xERA (2.69) and 73rd percentile in xBA (.218) through his first six starts, per Baseball Savant.
Cleveland’s bats haven’t been too shabby either to begin the 2026 MLB season, logging the 12th-best wRC+ (100), 14th-best wOBA (.319), and 13th-best ISO (.151), via FanGraphs.
Unlike Messick, there isn’t much red on Civale’s Baseball Savant page, as the experienced hurler is in the 35th percentile in xERA (4.58) and 19th percentile in xBA (.274). Seeing that Civale currently holds a 3.23 ERA, he’s likely headed for negative regression at some point.
The Athletics have been inconsistent at the plate so far, posting the 15th-best wRC+ (98), 10th-best wOBA (.323), and 16th-best ISO (.148).
