"In Cincinnati and Milwaukee, it maybe was affecting my swing," Lamb said of his hand. "After that, once I came back, it wasn't affecting the swing at all, it was just timing and staying within my approach. I'm just executing my approach, waiting for fastballs, hitting fastball. If you want to call it locked in, it's locked in, but I definitely feel good at the plate right now."
Entering Tuesday, Lamb was 3-for-his-last-36. After hitting 20 homers prior to the All-Star break, he had hit just one in 13 games after. That has since changed.
Lamb's team-best 24th homer broke a 3-3 tie in the fifth. He blasted a two-run shot to left-center field that traveled 423 feet with an exit velocity of 105 MPH and launch angle of 27 degrees, according to Statcast™.
D-backs manager Chip Hale is now seeing a more comfortable version of his slugging third baseman once again.
"Sitting him in the Milwaukee series [on the road] was a good thing for him," Hale said. "He didn't want to say anything, but you could tell his swing was different."
Lamb's homer was just the start of a big fifth inning for Arizona that broke the game open. Chris Owings later tripled in a run, and Phil Gosselin blasted a pinch-hit two-run homer to cap the five-run frame.
It was just the seventh time in franchise history that the D-backs hit five extra-base hits in the same inning.
"That's awesome. Hitting the ball hard everywhere, left side, right side, everyone running the bases well," Lamb said. "That's what this team's capable of, even with some of our guys out of the lineup with injuries. It was good to see it today and get the series."
