What happened: The organization recalled left-hander Nick Raquet from the Triple-A Norfolk Tides. Right-handed pitcher Cameron Weston was optioned to the minors to open a spot on the 26-man active roster.

Why it matters: This transaction brings a fresh arm to the major league club. The swap also gives the bullpen a different look for late-game situations.

What to watch: Raquet is available to pitch immediately as the team begins its series against the Chicago Cubs.
