Saturday's Best Games to Claim the BetMGM Bonus Code BOOKIESBG150 in MI

MLB: Los Angeles Dodgers at San Francisco Giants

  • Time: 4:05 p.m. EST
  • Starting Pitchers: Shohei Ohtani (LAD) vs. Landen Roupp (SF)
  • Venue: Oracle Park in San Francisco, California

Another great MLB game on Saturday features NL West rivals, the LA Dodgers and the SF Giants. This is a great matchup, especially since superstar Shohei Ohtani will start for the Dodgers. While the Dodgers have been struggling lately, Ohtani is a true star, and they have the better lineup, so this is a good opportunity for the Dodgers to get back on track with a big win.


Wimbledon: Iga Swiatek vs. Amanda Anisimova

  • Time: 11 a.m. EST
  • Venue: All England Lawn Tennis & Croquet Club in London, England
  • Moneyline: Swiatek -250/Anisimova +190

The finals of the women’s singles tournament at Wimbledon feature Iga Swiatek vs. Amanda Anisimova, in a matchup putting two of the top-10 ranked women’s tennis players in the world today. This should be an amazing match, but we lean toward Swiatek due to her experience, and we believe she is the rightful favorite here in the betting odds.


UFC Nashville: Tallison Teixeira vs. Derrick Lewis

  • Time: 6 p.m. EST
  • Venue: Bridgestone Arena in Nashville, Tennessee
  • Moneyline: Teixeira -275/Lewis +225

The main event of UFC Nashville is a five-round heavyweight bout between Tallison Teixeira and Derrick Lewis. Teixeira is one of the youngest and most talented up-and-coming prospects in the heavyweight division and appears to be a future contender. However, Lewis has been in the UFC for over a decade and continues to knock people out, so he has a puncher’s chance here despite Teixeira being a huge favorite to get his hand raised here.
