What happened: The San Francisco Giants have hired veteran third-base coach Gary Pettis, most recently of the Houston Astros, to take over their third-base coaching duties. Pettis replaces Hector Borg, who was removed from the role last week. Ron Wotus had been handling the position on an interim basis in the interim.

Why it matters: The move ends the Giants' search for a new infield coordinator at third with one of the more experienced names available, addressing a staff hole created when Borg was let go. Stabilizing the third-base box matters for baserunning decisions and game-flow calls down the stretch of the regular season. Pettis arrives described as a two-time World Series champion coach with decades of dugout experience.

What to watch: Pettis is set to join the team Wednesday after agreeing to the contract Monday. Watch how quickly he integrates with the existing staff and whether the change affects the Giants' aggressiveness on the bases.
