As the MLB trade deadline approaches, the Boston Red Sox and New York Yankees are aggressively pursuing key players to bolster their rosters. The Red Sox have already acquired reliever Lucas Sims and are eyeing top starter Jack Flaherty from the Detroit Tigers, while also engaging in talks for Angels' hitters Luis Rengifo and Taylor Ward. The Yankees, who recently added Jazz Chisholm Jr., are also interested in Rengifo and Ward and have been linked to top relievers like Chad Green. However, they have been ruled out of the race for White Sox ace Garrett Crochet. Both teams remain active in the market, with the Yankees also showing interest in Blake Snell from the Giants and the Red Sox possibly targeting Cubs' pitcher Jameson Taillon.
