What happened: The Philadelphia Phillies claimed infielders Brett Harris and Shay Whitcomb off waivers from the San Francisco Giants. In a corresponding move, catcher Garrett Stubbs elected free agency after being outrighted off the roster.

Why it matters: The waiver additions provide immediate infield depth to Philadelphia's 40-man roster at the start of the offseason. Stubbs' departure opens a vacancy at backup catcher after spending parts of multiple seasons with the club.

What to watch: Philadelphia will continue adjusting its 40-man roster ahead of upcoming offseason tender deadlines.
