Can Gavin Williams shake out of his funk and live up to the hype that followed him from last season before an early injury derailed his progress? A date with the Rays certainly could help as Tampa's offense has been flailing.

My analysis

Cleveland Guardians starter Gavin Williams was roughed up last time out by the Los Angeles Dodgers and didn’t even pitch his way out of the opening frame. Thankfully, the Tampa Bay Rays are in a completely different class and sport a 29th-ranked .290 wOBA against right-handed pitchers this season.

This is a bounce-back spot for Williams, and he also has a splash of statistical correction coming with his 5.25 ERA noticeably higher than his 4.13 xFIP, and his .303 BABIP is likely to lower while his 64% strand rate should climb. The 25-year-old righty posted respective 3.29, 4.53, .270, and 78.3% marks across his 16 starts last season, so while his surface numbers have been worse in 2024, there’s a case he’s also pitched better.

Tampa starter Ryan Pepiot has been just the opposite with his 3.66 ERA below his 4.17 xFIP and has negative regression ahead of his .255 BABIP and 74.8% strand rate. A date with the rolling Guardians isn’t ideal, either. Cleveland ranks fifth with a .333 wOBA and .333 on-base percentage during its highlighted 9-4 stretch.

The final piece of the puzzle is the Cleveland bullpen sporting the lowest ERA (2.74) in baseball and second-lowest xFIP (3.66). I'm happy to back the better top-to-bottom team on the moneyline.

Gavin Williams to record the win

Ryan Pepiot Over 1.5 walks allowed

A quick peek at Williams’ game log showcases seven consecutive starts against teams positioned to play in the postseason, and again, Tampa Bay isn’t in the same class. As noted, I expect a bounce-back showing against a softer opponent and Williams completing five frames to position himself for the win.

Pepiot has issued six free passes across his past two starts, and his command has been inconsistent all season with a  3.19 BB/9 and 8.6 BB%. He has two or more walks in half his 2024 starts, too.

Rays vs Guardians moneyline and Over/Under analysis

  • There has been a noticeable move to the Cleveland side of this moneyline, with Pinnacle opening Guardians -135 and adjusting to -145 as of Thursday morning.
  • Cleveland also moved 10 points at bet365, and I don’t expect there to be buyback on the Rays unless there are additional moves to the Guardians side.
  • While there has been back-and-forth action on this 7.5 total at Pinnacle and bet365, both shops are back at the opening 7.5 with the Over carrying the higher vig.
  • It’s notable that Pinnacle quickly moved to an 8.0 total and it lasted throughout the night.
