WHAT IT MEANS: Ike Davis produced the ninth three-homer game in franchise history, but the solo shots could not offset Chris Young's subpar outing, and the Mets lost to the Diamondbacks 6-3 Saturday night at Chase Field.

The Mets dipped to a season-worst five games under .500 with their 13th loss in 15 games since the All-Star break.

Davis joined Carlos Beltran, Jose Reyes, Edgardo Alfonzo, Gary Carter, Darryl Strawberry, Claudell Washington, Dave Kingman and Jim Hickman as the players to homer three times in a game with the Mets.

Reyes' three-homer feat was the only other to occur in a loss.

According to ESPN Stats & Information, Davis became only the fifth player in the live-ball era (since 1920) to produce all of his team's runs in a loss via three solo homers. The others: Steve Finley (Diamondbacks, 2004), Eddie Murray (Orioles, 1980), Gus Bell (Reds, 1955) and Clyde McCullough (Cubs, 1942).

Davis now has a team-leading 20 homers -- establishing a career high, which tops the 19 long balls he produced during his rookie season in 2010. This was Davis' third career multihomer game.

Since June 12, Davis has produced 15 homers. That is one shy of the most in the majors during that span. Arizona's Jason Kubel has 16.

Davis' first two shots Saturday night, which went to dead center, were estimated at 435 and 445 feet, respectively.

Davis went 4-for-4, matching his career high for hits. He had three four-hit games in 2010. He was left on deck when the game ended.

Young's outing, however, deprived a celebratory feel to Davis' performance.

Young dropped to 0-4 in his past five starts by surrendering six runs on seven hits and two walks in four innings.

A half-inning after Davis' second homer had pulled the Mets within a run in the fourth, Young surrendered a two-run homer to Miguel Montero in what became a three-run frame that staked Arizona to a 6-2 lead.

BAY WATCH: Jason Bay went 0-for-4 with two strikeouts. He is now 0-for-his-last-19, dropping his batting average to .164. Terry Collins has stated his intention to have Bay start Sunday against left-hander Joe Saunders, but Bay's playing time should diminish against righties.

The Mets, though, face southpaws in three of the next five games. They see Madison Bumgarner on Monday and Barry Zito on Thursday in San Francisco.

K-IRK: Kirk Nieuwenhuis struck out three times while going 0-for-4. Nieuwenhuis, who is the likely candidate to be demoted when Mike Baxter returns for the Giants series, has now struck out 98 times in 282 at-bats during his rookie season.

WHAT’S NEXT: R.A. Dickey (13-2, 2.97 ERA), coming off only his second loss of the season, opposes Saunders (5-6, 3.51) at 4:10 p.m. ET Sunday as the teams complete a four-game series. Dickey has a 6.49 ERA this month.
