Giants vs Rays Pick, Betting Analysis
This is a great price to support Tampa Bay, which should sweep the series today.
The Rays have won eight of their last 10 games and have a 10-4 record at home.
They also have a clear edge on today's pitching matchup, with Steven Matz coming off a great outing against the Guardians (two earned runs and four hits in seven innings) against a struggling Tyler Mahle, who sports a .321 BABIP.
Matz will face a weak Giants offense that ranks next-to-last in the majors in wRC+ with 82. Mahle, on the other hand, was just pummeled in his last start against the Phillies, giving up five runs in five innings.
Back Tampa to finish the series in style.
Pick: Rays ML (-120, BetMGM)
