MATCHDAY: The First True Test -- MacMath, Union Welcome Star-Studded Galaxy to PPL (7:30 p.m., CSN)

In my season preview, I said this about Zac MacMath:

It’s put up or shut up time for MacMath. ... MacMath is immensely talented and amazingly athletic, but from where I sit, it’s time for the 21-year-old, former first-round pick to put the team on his back and win a few games on his own this season.

Well, that happened on Saturday.

MacMath was off the charts in the Union's 1-0 win in Chicago last weekend. None of his six official saves were better than this one in the final 30 seconds.

No one has ever questioned MacMath's athleticism. But his decision-making is questionable at best and wildly inconsistent at worst. If he can put it together and play like he did Saturday, this team could go far.

For the first time this season, someone other than Jack McInerney was the star of a Union win. So with Landon Donovan, Robbie Keane and the LA Galaxy coming to PPL Park tonight -- likely meaning plenty of chances for MacMath to save the Union's bacon -- it's a perfect time for the casual fans to learn a little more about Mr. MacMath (a trend we'll continue occasionally throughout the season).

How He Got Here: MacMath -- a star at the University of Maryland -- was the fifth overall pick in the 2011 MLS Draft, the Union's second-ever draft. He is the only goalkeeper drafted in the first round since 2009 (Stefan Frei, Toronto), and one of just 11 goalies ever taken in the first round since the league began drafting college players in 1996. Only three goalies have ever been picked higher: Former Union player Chris Seitz (4th by Salt Lake in 2007), budding English Premier League star Brad Guzan (2nd by Chivas in 2005) and Adin Brown (3rd by Colorado in 2000).

Why Fans Love Him: The 21-year-old MacMath is incredibly athletic. He has incredible reflexes and his six-foot frame can reach all four corners of the net.

Why Fans Are Frustrated By Him: Expectations, plain and simple. The Union spent a high pick on MacMath, and gave him an experienced veteran to learn from in fan favorite Faryd Mondragon. His name was mentioned as the next in a long line of American goalkeepers -- the one position where the United States stands out in the soccer world.

He seems to doubt himself at times, come out on balls when he shouldn't, and stay on his line when he should be more aggressive. In the last home game against Seattle, he made two saves while STANDING INSIDE HIS OWN NET -- one which resulted in a goal and one that he got away with. This only served to illustrated his sometimes-shaky sense of control over his own penalty area -- something Mondragon excelled in.

That's another thing working against MacMath's perception among Union fans: Faryd Mondragon. The Colombian was a fan favorite during his one season in 2011, and has an INCREDIBLE command over his penalty area and defenders. He was constantly barking out instructions, consoling defenders after mistakes, and constantly teaching and directing his teammates. MacMath needs to remember some of the lessons he learned from Mondragon and realize this is his ship now.

You Know He'll Have a Good Night: When he makes a big save early, like he did on Saturday. MacMath then seems engaged and in control, and more aggressive coming off his line.

Union Highlight: In my opinion, Saturday's game against Chicago was MacMath's best game as a Union player. He also saved a penalty kick in a crazy 1-1 draw against DC United last year.

Where Does He Go From Here: Based on his age and athleticism, MacMath still could be a top goalkeeper in this league, and eventually parlay that into a European career, should he so choose. But he has a long way to go on the consistency and confidence front. For now, he needs to be someone that Union fans don't need to worry about on a game-by-game basis.

Today's Game:

Philadelphia Union (4-3-2, 15 points) vs. LA Galaxy (4-3-2, 14 points)

7:30 p.m. -- PPL Park -- TV: Comcast SportsNet

Prediction Sure To Be Way Off:

The Union seem to be finding their way, and Jack McInerney is hotter than any forward in the world not named Lewandowski. And the Galaxy are still finding their way with Landon Donovan back from his self-imposed vacation (another post for another day). But LA is still LA. The Union will get one early and sneak in another. But they'll struggle to hold the lead, before giving it up and settling for a draw.

Union 2, Galaxy 2.

Union-Red Bulls 5 things: Aim to finish strong against streaking New York

Union-Red Bulls 5 things: Aim to finish strong against streaking New York

Union vs. New York Red Bulls
4 p.m. on TCN 

Having all but officially made the postseason for the first time since 2011, the Union, who are already locked into a first-round road match, could rest players Sunday in the season finale against the New York Red Bulls (15-9-9). But that doesn’t mean the Union (11-13-9) will be mailing it in.

Here are five things to know.

1. Playoff recovery
The Union had hope that last Sunday’s home match against mathematically eliminated Orlando City SC would work as a slump buster, breaking the club’s five-game winless run. 

Instead, with a 2-0 loss, it just extended the Union’s slump to six.

“We had a good meeting with the group, we talked a lot about accountability,” Union manager Jim Curtin said. “Everybody does have to look in the mirror.”

With their last win coming in late August, the Union seem fresh out of ideas. Passing up the ripe opportunity to gain confidence against Orlando City, the club must now host the best team in the Eastern Conference as a pre-playoff test.

“We shot ourselves in the foot in a big spot and we came up a little short,” said Curtin, whose club flubbed an outside chance to host a first-round game and will be on the road regardless of Sunday’s outcome. “It’s the past, though. We have to look forward to the challenge that Red Bulls will present. They are the perfect team to play in terms of a tuneup, to get up to speed with the tempo of a playoff game. It’ll be good for our guys, we’ll use that to get prepared.”

2. Refreshing the lineup
Because Sunday’s match comes just days before the Union’s midweek postseason game, Curtin could look to rest some starters against the Red Bulls, especially the injured ones.

“There are discussions,” he said. “You have to do what’s best. Maybe it’s a new face, a change or a tweak. We won’t change our formation, we won’t change the style that we play but maybe there’s a new body that comes out on the field and gives us a little bit of a lift.”

But Curtin’s team doesn’t just need a lift, it needs healthy bodies. C.J. Sapong suffered a concussion against Orlando City and will likely sit out Saturday. If he does, Charlie Davies could see a chunk of playing time. Davies has only played 81 minutes in eight games since being acquired by the Union in August.

Tranquillo Barnetta and Chris Pontius are also banged up with lower-body ailments.

“Charlie’s been a little bit sharper each day in training,” Curtin said. “It’s tough to forget that he as recently as a month and a half ago was beating cancer so, the sharpness and the fitness is starting to come back. He wants to start, he wants to play, like any striker does, but we have to be smart about what makes the most sense for the team to get a result this weekend.”

3. Mighty Red Bulls
With the Red Bulls already locked into a first-round playoff bye, claiming the top seed in the East, they could float into Sunday’s match like it’s an exhibition — resting starters and providing minimal effort. 

But while riding an unbeaten streak that dates back to early July, the Red Bulls aren’t likely to pull their foot off the gas just yet.

“It’s a challenging game for us,” Curtin said. “It’ll be a high tempo, playoff atmosphere. With Red Bull already securing their bye, I envision them playing their full-strength lineup because they don’t want to rest guys for two weeks, and then you could have some rust. We expect their best.”

Though the Red Bulls want to keep things moving Sunday, the Union also want to finish the season strong. Although the match doesn’t hold the importance it could have for either club, Curtin’s team, winless since late August, is grasping for anything it can to catapult itself into the postseason with momentum. 

“We want to finish the season the right way for our fans,” Curtin said. “We want to come out with some confidence after the game.”

4. Keep an eye on …
Union: With Sapong hobbled from a concussion, Sunday’s match could put Charlie Davies’ effort on display. The forward, who has been seldom used as he regains conditioning after beating cancer earlier in the year, was acquired by the Union for this exact scenario — providing quality attacking depth.

Red Bulls: Although the match is practically meaningless for the Red Bulls, it could mean something for Bradley Wright-Phillips. The 31-year striker could claim his second golden boot in three seasons. He currently leads MLS with 23 goals — one ahead of David Villa. He has a goal and an assist against the Union this season and 11 goals in his last nine games.

5. This and that
• The Union are 0-1-1 against the Red Bulls this season but did score a win in the U.S. Open Cup round of 16.

• The result of Sunday’s match will leave the Union with one of three postseason road opponents — New York City FC, Montreal Impact and D.C. United. The match will be played the following Wednesday or Thursday.

• With a win on Sunday, the Union would match a club-high in wins with 12 — a record set in 2013.
