Thursday trading preview

  • Mets to win (45%)
  • Wings to win (56%)

MLB returns from its break with a single game on Thursday -- a New York Mets vs. Philadelphia Phillies rivalry matchup that pits New York's Christian Scott (2-1, 3.47 ERA) vs. Philadelphia's Aaron Nola (3-6. 5.75). The Mets entered the break on a three-game losing streak, but Scott has been decent in his return from a long injury layoff. The veteran Nola hasn't recorded a win since late May. New York is destined for a trade deadline sell-off but provides decent trading value to record a win on Thursday.

Another New York team facing strong opposition on Thursday is the New York Liberty, who will be in Dallas to take on the Wings. Pagie Bueckers and the Wings have won five straight while the Libs have dropped three in a row. It will be a tough ask for the Liberty to knock off a team in such strong form in their own house, so backing the Wings feels like the way go. Trade on MLB, the WNBA and more with the Polymarket promo code SPORTSLINE:
