The Mets took advantage of the Diamondbacks having to pitch a bottom-of-the-end rotation guy on Tuesday. But now Arizona is coming in with its ace, Zac Gallen.

Gallen doesn't pitch as well on the road, but he's still a stud and in the NL Cy Young Award conversation with a 15-7 record and 3.31 ERA. Opponents are batting only .229 against him.

The Diamondbacks are battling hard with five other teams for a wildcard playoff spot. They have incentive. The Mets don't. They are 12 games below .500. Mets manager Buck Showalter is trying to balance his veterans with youth knowing his team is in rebuild mode.

I'd stay away from this game if the Mets were going to pitch Kodai Senga because he's tough at home. But the Mets are giving Senga extra rest. Instead they are starting journeyman Joey Lucchesi, who hasn't pitched since Aug. 19. Lucchesi has made six starts this year. Only one was a quality start. So the Mets could be turning to their bullpen early.
