The Mets’ outfield is an Amazin’ Mess, and fans cannot blame Willie Randolph for this one.

The Mets (22-22) have looked abysmal in their first three games in Atlanta, getting outscored by the Braves 23-7. And with another game in Atlanta came another injured outfielder.

To call Moises Alou often-injured would be a gross understatement.

Alou, who missed the first 26 games of the season with a hernia, left last night’s 11-4 loss in the third inning after he strained his left calf. That’s one day after Ryan Church suffered a mild concussion.

Randolph said Church could be available for pinch hitting tonight (7, SNY, WFAN) when the Mets try to salvage one game before heading to Colorado.

“He’s got to really convince me that he’s ready to go,” Randolph said of Church. “We’re going to be ultra-cautious with him, because, like I said, when you’re dealing with the head injuries, you don’t want to mess with that.”

The options for the Mets in the outfield are limited. Endy Chavez replaced Church last night and went 0-for-4. Marlon Anderson came in when Alou went down and he proceeded to go 0-for-3. Damion Easley is another option, but not a popular one at this point.

This is all happening with Angel Pagan, who subbed admirably when Alou recovered from his hernia injury, is also on the disabled list.

Randolph would not let the injuries serve as an excuse for another disappointing effort from his team.

“It’s not acceptable,” Randolph said. “That’s not the way we want to play baseball.

“Talking about it’s not going to get it done for you.”

The Mets’ hitting woes and the specter of a four-game sweep by the Braves (25-21) makes Johan Santana’s 10th start as a Met his most important. He will face a Braves team that owns the best home record in baseball, 19-5.

“That’s what I’m here for,” Santana said. “That’s what I want to do. I know exactly what my role is, and every time they want me to get the ball, I’ll just try to do it. I’m here to help this team win games, and I’m pretty sure everybody feels the same way.

“Every time I go out there, I’m trying to make it very special.”

Tonight’s Pitching Matchup:

Mets LHP Johan Santana (5-2, 3.30 ERA) Santana has allowed 11 homers in 60 innings this season. He lost his previous start at Turner Field, allowing one run over seven innings in a 3-1 defeat.

Braves RHP Tim Hudson (6-3, 3.06 ERA) Hudson had a solid season, but has struggled in his two starts against the Mets, going 1-1. He battled through six innings, giving up three runs when the Braves pummeled the Mets 11-5 in the teams’ first meeting of the year. Then he went three innings in his worst start of the season, giving up four runs in a 4-3 loss at Shea on April 26.
