"Nobody is making any outgoing calls on Madison Bumgarner," Zaidi said, via the San Francisco Chronicle's Henry Shulman. "If a team calls about any of our players, we're in a position where we have to listen."
Zaidi added that the team's goal is to be competitive in 2019, and he sees the four-time All-Star as a "central cog" in that effort. He also didn't dismiss a recent report from MLB Network's Jon Morosi connecting the Giants and Milwaukee Brewers for a potential Bumgarner swap.
However, Tom Haudricourt of the Milwaukee Journal Sentinel reports the Brewers aren't currently talking to the Giants about a trade.
The 29-year-old ace only logged 129 2/3 innings in 2018 after a bone broke in his pitching hand when a line drive hit him during a spring training game. He still finished the season with a 3.26 ERA, 1.24 WHIP, and 109 strikeouts.
