Baseball’s top spenders are struggling with injuries and roster challenges as the trade deadline approaches. The New York Mets, with a big league-high $326 million payroll, lead the NL East but have a losing record since mid-June. The Los Angeles Dodgers, spending just $200,000 less, lead the NL West but have also struggled since early July. The New York Yankees, third in spending, have lost their division lead due to a poor stretch since late May. Despite being playoff contenders, these teams haven’t met expectations. Injuries have forced them to use numerous starting pitchers and adjust lineups frequently.
