What happened: The San Francisco Giants acquired minor-league left-handed pitcher Tony Neubeck from the Washington Nationals in exchange for infielder Nate Furman. The clubs completed the one-for-one swap on Monday.

Why it matters: Trading Furman creates flexibility for the Giants as the front office navigates a tight 40-man roster crunch heading into the offseason. In return, San Francisco adds organizational pitching depth from the left side, while Washington adds to its minor-league infield mix.

What to watch: Both clubs will continue adjusting their 40-man rosters ahead of upcoming winter roster deadlines.
