Monday trading preview
- Kyle Schwarber to win Home Run Derby ($0.22)
- Lynx to win vs. Mercury ($0.87)
It's hard to predict who will win the Home Run Derby given the nature of the event but backing the current MLB home runs leader in his own ballpark seems like a safe trade to make. Schwarber has been mashing all season, though there could be some potential underdogs worth backing in Yankees star Ben Rice and Rays young phenom Junior Caminero. Rice has been a huge boost in Aaron Judge's absence, while Caminero is on pace to top the 45 home runs he had a year ago. Schwarber's teammate Bryce Harper has previously won the Derby but he's not among the top contenders in this year's competition.
Even with Napheesa Collier sidelined, the Minnesota Lynx have been one of the best teams in the WNBA thanks to rookie sensation Olivia Miles and rising forward Natasha Howard. Miles, Howard and the Lynx could briefly pull ahead of the Las Vegas Aces for the league's best record on Monday if they defeat the Phoenix Mercury, who are coming into this game off a massive 106-58 loss to those Aces. Minnesota has won two in a row and is highly likely to take advantage of a struggling Phoenix squad tonight. Trade on the Home Run Derby, WNBA and more with the Polymarket promo code SPORTSLINE:
