Best bets for Sunday, March 29
The Seattle Mariners aren't looking past the Cleveland Guardians, even though a series with the Yankees starts Monday. The Mariners made the ALCS last season, but the Guardians won the AL Central for the second straight year, and they split the first two games of the series. The Guardians won Saturday night, 6-5. Seattle is expected to start Emerson Hancock (4-5, 4.90 ERA in 2025) opposite fellow right-hander Slade Cecconi (7-7, 4.30). The SportsLine Projection Model, which simulates every game 10,000 times, likes the Mariners to get the job done. They are winning in 61% of simulations.
The Oklahoma City Thunder continue to have a target on their backs, but few have been able to hit the bull's-eye. The Celtics are the only team to beat OKC in its past 13 games, but another Eastern Conference hopeful will take a shot Sunday. The New York Knicks visit Oklahoma City on a run of seven victories in their past eight. The most recent was a 113-104 loss to the sizzling Charlotte Hornets, but Jalen Brunson and Co. will be motivated Sunday after falling 103-100 to the Thunder on March 4 in their only other meeting of the season. The SportsLine model likes the Knicks to cover the spread, as they do so in 57% of simulations.Â
