Hudson, making his second start since coming off the DL, made a big impression with eight strong innings to help the Diamondbacks to a 4-2 win over the San Diego Padres.
Paul Goldschmidt extended his hitting streak to a career-high 11 games with a solo home run, and Arizona's struggling offense was resourceful in scoring four runs.
But Gibson, a fierce competitor in his playing days, was taken by the intensity Hudson showed. Especially after he paid Hudson a visit when the right-hander walked the leadoff batter in the eighth inning.
"The Huddy of old," Gibson said. "He threw great. He didn't want to come out. His pitch count was pretty low. I went out and he's always lobbying for longer. I didn't want to take the game away from him, so I stayed with him. That's what we needed."
Hudson, who missed more than a month with a right shoulder impingement, allowed two runs on five hits while striking out five and walking one. Hudson also had a sacrifice fly.
"He was wondering why I walked (Everth Cabrera) when I was up 0-2," Hudson said about Gibson's mound visit. "He asked me how I felt and I said I felt fine. He said, 'Try and get a double play and get out of this thing.'"
Hudson didn't get a double play but retired the next three batters to cap a solid outing.
"He kept the ball down and got quick outs," catcher Miguel Montero said.
When Montero was asked about Gibson's decision to keep Hudson in the game, he said, "I would have done the same thing. His fastball was still good and his slider was outstanding."
Arizona, which had scored two runs or less in three of its previous four games, scored three runs on a sacrifice fly, a balk and a bases-loaded walk.
"Right now, you have to take whatever they give you," Montero said.
The Diamondbacks got an assist from San Diego reliever Joe Thatcher, who balked in the go-ahead run in the seventh inning.
Gerardo Parra reached on a comebacker that deflected off Thatcher's bare hand and went for an infield single with one out in the inning. Willie Bloomquist singled and Parra advanced to third base. Thatcher was then called for a balk by third base umpire Brian Gorman, allowing Parra to score.
"(Parra) caused the balk," Gibson said. "He took a couple of steps. He went down (the third base line) hard where Thatcher could see him."
Thatcher and manager Bud Black did not agree with the call.
"He (Gorman) took the ball out of my hands," Thatcher said. "I'm looking back at the second base umpire, he's shaking his head. I didn't balk. I don't know what he really saw. It changed the game."
Goldschmidt's home run in the fifth inning into the second deck in left field made it a 2-2 game.
San Diego, which broke a six-game losing streak with Friday night's 7-1 win over Arizona, has lost 10 of 12. The Padres have the majors' worst record at 18-36.
The Diamondbacks failed to fully capitalize on San Diego starter Edinson Volquez's wildness.
The Padres right-hander walked consecutive batters to open innings in both the second and fourth innings, but Arizona managed to score just one run.
The Padres took the lead in the bottom of the inning after Will Venable led off with a bunt single and stole second. Cameron Maybin followed with an RBI single and took second on the throw home before he scored on Yonder Alonso's single.
Volquez allowed two runs on four hits over six innings. He walked a season-high five and struck out five.
In his last four starts, Volquez has received just three runs of support but also has walked 15 batters. ...
