Wednesday MLB trading preview
The Seattle Mariners upset the Los Angeles Dodgers on the road 7-6 last night after hitting a season-high five home runs, including two by Dominic Canzone. This momentum-boosting win for the Mariners, who are balancing a near-.500 record, may help decide how to maneuver their roster as the trade deadline nears, just a week away. Meanwhile, the Dodgers hope to bounce back as their one-run loss at home temporarily dropped them down to a tie with the Brewers for the top seed in the National League. However, since Los Angeles hasn't lost two games in a row since early July, Kalshi has the Dodgers priced at $0.59 per share to win tonight against the Mariners, who are priced at $0.43. Kalshi allows users to trade on home runs, and in a series that is loaded with star talent, Cal Raleigh ($0.28), Shohei Ohtani ($0.27), Julio Rodriguez ($0.21), Randy Arozarena ($0.19), Freddie Freeman ($0.19) and Mookie Betts ($0.14) are all trading for these prices per share to hit a home run.Â
The Chicago White Sox lost the first two games in their series at home against the New York Yankees. As of Wednesday, they hold a 1 ½ game lead in a tight AL Central race that includes the Guardians and Twins within two games of the top spot. The Yankees jumped to trailing the Rays by only 1 ½ games in the AL East after last night's win. Tonight's Game 3 of their four-game series will be nationally streamed in primetime, and the Yankees will have their ace and frontrunner for the AL Cy Young Award on the mound. Cam Schittler is trading for $0.62 on Kalshi to have seven or more strikeouts. In July, Schittler is averaging 8.5 strikeouts per start. Kalshi also has tonight's game shaping up in favor of New York, with the Yankees at $0.58 per share to win against the White Sox, who are priced at $0.43.
Weather has factored into the battle for the Ohio Cup, and after yesterday's doubleheader between the Cleveland Guardians and Cincinnati Reds, the series is split 1-1. Guardians' pitcher Joey Cantillo is on the hill and is priced at $0.43 on Kalshi to have 6 or more strikeouts. A win in this series doesn't just mean state bragging rights; Cleveland is trying to chase down the White Sox for the AL Central as they are 1 ½ games back going into Wednesday's meeting. However, for Cincinnati, who is at the bottom of their division, hope to turn things around starts with a series win. Jose Ramirez, who is tied for 3rd in stolen bases in the league, recorded his 25th and 26th for Cleveland last night, and he is trading at $0.21 on Kalshi to have at least one this evening. The Guardians are priced at $0.56 per share to win over the Reds, priced at $0.45. Trade on the MLB and more at Kalshi with the promo code SL500:
