PHILADELPHIA -- After beating up on the Washington Nationals all weekend, the Atlanta Braves reached a point Monday night where they appeared to be rolling toward a nice, methodical win over the Philadelphia Phillies. Then the momentum began whipsawing in umpteen different directions and vertigo took hold in the dugout, and it was the kind of game when bald managers make jokes about how they’re glad they don’t have any hair to turn gray.

“It was almost like two different games out there tonight,” said Braves manager Fredi Gonzalez.

Atlanta’s second most reliable reliever, Luis Avilan, morphed into a human line-drive dispenser in the eighth inning to turn a 5-1 lead into a 6-5 deficit. Then Dan Uggla, a power hitter who entered Monday night with a .195 average and zero homers in his first 41 at-bats this season, lofted a grand slam into the left-field seats in the top of the ninth to give the Braves a 9-6 lead they wouldn’t relinquish.

And then, when the bullpen gates swung open and everyone expected All-Star closer Craig Kimbrel to come jogging out to nail it down, out came David Carpenter, who was pressed into service because Kimbrel has a sore right shoulder. (Nothing serious, Kimbrel insists. But he still might require a “few days” of rest and maintenance to get back on the mound.)

It’s hard to tell precisely what lesson to draw from the aforementioned sequence of events. But if you begin with the premise that resilience is paramount during a 162-game season, that’s a pretty good start.

“That’s baseball,” Uggla said. “A comfortable win turns into an uncomfortable loss sometimes -- or an uncomfortable win. It’s just the way the game is. You can never think that things are going to work out a certain way.”

If anyone can grasp that concept, it’s the Braves, who have to be feeling pretty good about themselves with their 9-4 start, given the numerous unsightly alternatives.

Think back a little more than a month ago, when Kris Medlen and Brandon Beachy learned they would need Tommy John surgery and the Atlanta rotation bordered on wrecked beyond repair. A pessimist might have described the projected Opening Day rotation as “Teheran and Wood, and not very good.”

Things have fallen into place quite nicely since then. Aaron Harang, picked up by Atlanta in late March after he was released by Cleveland, has been terrific, with a 0.96 ERA and a .145 batting average against in three starts. Reinforcements are on the way, with Mike Minor close to returning from a shoulder issue and Gavin Floyd (recovering from his own Tommy John surgery) not far behind. And the Braves just might have found themselves a new ace in Ervin Santana, who is giving Stephen Drew and Kendrys Morales a primer on how an unemployed free agent can cut his losses and make the best of a bad situation.

Like Morales and Drew, Santana was trapped in free-agent compensation hell before downsizing his expectations and signing a one-year, $14.1 million deal with Atlanta on March 12. Two starts into his tenure with the Braves, he has a 0.64 ERA and 17 strikeouts in 14 innings, and he’s showing that a full complement of spring training innings can be highly overrated.

Santana was lights-out in his National League debut with eight scoreless innings against the Mets, and was almost as formidable against the Phillies. He struck out 11 batters in six innings, with every one coming on a swing and miss. Santana complemented a mid-90s fastball with an effective slider and changeup that induced an abundance of tentative, awkward swings.

“He has three plus pitches and he attacks hitters,” said a scout who watched Santana at Citizens Bank Park on Monday. “A lot of swings and misses. We all wondered how he stayed out there on the market that long. Money, I guess. But he’s pretty good.”

Santana insists he doesn’t have any extra motivation after a winter of anxious unemployment. But it’s clear he made the right decision to take the plunge and go back on the market when he did.

“I don’t have to prove anything,” Santana said. “Just be me and pitch every time I take the mound. It was tough for me to get a job with the draft compensation being part of the deal. I don’t want anything bad for anybody. But injuries happen. That’s part of the game. When [the Braves] reached out to me I said, 'OK, let’s do it.’”

Gonzalez knew Santana would be a good fit in Atlanta when Kansas City GM Dayton Moore and manager Ned Yost, two old friends, both called him and raved about Santana as a person, a professional and a competitor from his days with the Royals. If Gonzalez is surprised about anything to this point, it’s that a pitcher as slight as Santana can summon so much life from that right arm. The dreadlocks merely add to Santana's aura.

“If you took a poll of people who didn’t know baseball and said, ‘What does that guy do for a living?’ I think baseball would be the last thing they’d think,” Gonzalez said. “They’d probably say this guy is an artist or a singer.”

Santana is 1-0 through two starts, and Atlanta’s supporting cast showed enough signs of life to bode well for him and the rest of the Atlanta staff moving forward:

• Evan Gattis, who hit two home runs Monday, is a career 4-for-20 at Citizens Bank Park. All four of those hits are home runs.

• Andrelton Simmons, Atlanta’s all-world defensive shortstop, went 3-for-5 and is now hitting .341 this season. He has yet to strike out in 41 at-bats.

• Uggla committed a throwing error, but he made two sensational plays in the field and sent two balls into the seats. If the Braves plan on maintaining their early momentum, they need Uggla, Gattis and the rest of the lineup to give Freddie Freeman and Justin Upton some help over the coming weeks and months.

“We have a lot of guys who can change the game with one swing,” Uggla said.

For now, the Braves are just happy to be in “weathered-the-storm” mode. After hitting rock bottom in spring training, they're fully prepared for the wild emotional swings that a baseball season brings. Some nights that trait comes in handier than others.
