With rain in the forecast again Saturday, the Mets will try to begin finding some consistency and beat the Diamondbacks for a sixth straight time.Friday's opener was called because of rain in the fourth inning and will be made up as part of a single-admission doubleheader on Sunday.Before that, New York (21-25) will look to put together a strong overall stretch after winning for just the second time in eight games Thursday, beating the Los Angeles Dodgers 5-3."We're trying to do some stuff, but as I told some of the guys, this is when you find out if you can play here," manager Terry Collins told the team's official website. "Grind this out, get through it, and when we start swinging the bats and we got hot, we'll be back on the horse. We're not playing good."The Mets' starting rotation has been rather impressive in winning the last five meetings with the Diamondbacks (18-31), compiling a 2.05 ERA. The starters allowed two runs in 18 1/3 innings while sweeping a three-game set at Arizona from April 14-16.Zach Wheeler (1-4, 4.53 ERA) opened that series by allowing two runs in 6 1/3 innings of a 7-3 win. The right-hander was also solid in his only other start against the Diamondbacks on Aug. 10. He yielded one run while leaving with one out in the seventh of a 4-1 victory -- the first of the Mets' five straight in the series.Wheeler, though, is 0-2 with a 4.45 ERA over six starts since last facing Arizona. In Sunday's 6-3 loss at Washington, he allowed five runs -- three earned -- in six innings."It's been a bunch of bad starts in a row here," Wheeler said, "so I need to hurry up and turn it around and get back on the right track."The Diamondbacks batted .154 and totaled four runs while being swept in a three-game set with St. Louis, capped by Thursday's 4-2 defeat -- its fifth in seven games.Aaron Hill is hitless in 11 at-bats over the past three games, and he had a two-run homer wiped out by the rainout Friday."Good old New York," said Hill, who went 5 for 15 in four games at Citi Field last year.Josh Collmenter (2-2, 4.02) is expected to get the ball, and he's 2-0 with a 3.72 ERA over his last five starts.The right-hander was credited with a 5-3 home win over the Los Angeles Dodgers on Sunday, yielding three runs and two homers while exiting with one out in the sixth inning."I was down in the zone, and that's something that I've been really focusing in on," Collmenter told the team's official website. "My fastball plays a lot better when it's down in the zone."He's 1-2 with a 4.91 ERA in seven meetings with the Mets, but he's surrendered eight runs and 12 hits -- two homers -- in 10 innings while splitting two starts.He'll now try to slow down Curtis Granderson and David Wright.Granderson is 7 for 16 (.438) with four extra-base hits in the last four games, while Wright is 10 for 25 in the past six.Wright owns a .343 average with six RBIs and as many runs over his past eight meetings with the Diamondbacks, collecting five hits while plating three runs and sparking last month's sweep at Arizona.
Hitters have a .397 OPS and are striking out 38.5 percent of the time when Zack Wheeler throws his fastball up in the strike zone. A.J. Pollock has a .638 OPS against fastballs up in the zone, which is 95 points worse than the league average.
