WIMBLEDON – For the first time this year, a Grand Slam tournament actually starts on a Monday in the U.S. – as it should be.

The Australian Open, with the 16-to-19 hour time difference, begins Sunday night in the U.S.. The French Open has a 15-day schedule and starts on Sunday.

But promptly at 1 p.m. London time (8 a.m. EST, 5 a.m. PST), reigning Wimbledon champion will walk onto Centre Court, to the hushed and awed applause of the patrons (to steal an expression from the Master's), and officially kick off this year's edition.

Here's the complete order of play.

And here's the weather forecast for Monday (not great - 40 per cent chance of afternoon showers)

Here are some things to look out for Monday.

Americans on tap

Men's singles

[Q] Ryan Harrison vs. [11] Grigor Dimitrov (BUL) - Two players close in age, but one who has yet to fulfill his early hype against another who is doing just the opposite this season.

[Q] Alex Kuznetsov vs. [16] Fabio Fognini (ITA)
Steve Johnson vs. [27] Roberto Baugista-Agut (ESP)
Bradley Klahn vs. Sam Querrey
Donald Young vs. Benjamin Becker (GER)

Women's singles

[18] Sloane Stephens vs. Maria Kirilenko (RUS) - Kirilenko missed time with injury, and after her engagement to hockey superstar Alex Ovechkin hasn't appeared overly eager in her few tournaments back.

[30] Venus Williams vs. Maria-Teresa Torro-Flor (ESP) – The elder Williams has a good draw. Will her health and nerve allow her to take advantage of it?

Coco Vandeweghe vs. [27] Garbiñe Muguruza (ESP) - Vandeweghe just won her first career WTA Tour title Saturday, on grass no less. Muguruza is one of the hot "young" up-and-comers on Tour, even though they're practically the same age.

Vania King vs. Yvonne Meusburger (AUT)
Lauren Davis vs. Alisa Kleybanova (RUS)
Varvara Lepchenko vs. Tsvetana Pironkova (BUL)

Upset alerts

(Not saying they WILL happen. Just saying they could get sticky)

[14] Jo-Wilfried Tsonga (FRA) vs. Jürgen Melzer (AUT): Melzer is a former top 10 player (and Wimbledon doubles champion) coming back from shoulder surgery. And a lefty. And Tsonga's season has been awfully full of ups and downs. He's 4-0 against Melzer, losing just one set in those meetings, and defeated him in three straight sets a couple of weeks ago in the second round of the French Open. But it's a different surface.

Yanina Wickmayer (BEL) vs. [17] Samantha Stosur (AUS): Stosur, for whatever reason, hasn't ruled the grass in singles the way she ought to. Wickmayer, while not what she was a few years ago, can still have her moments.

[6] Petra Kvitova (CZE) vs. Andrea Hlavackova (CZE): It's not so much the opponent as Kvitova herself. The former champion pulled out of a tune-up event last week with a hamstring injury, and she was sporting a hefty wrap job in practice over the weekend.

[14] Sara Errani (ITA) vs. Caroline Garcia (FRA): Errani's best surface is clay. And she's having a down year as the field finally has caught up to arguably the slowest serve of any top female player, ever. Garcia can get nervous, but she has little to lose.

[21] Alexandr Dolgopolov (UKR) vs. [Q] Sam Groth (AUS): Dolgopolov, by all accounts, isn't particularly healthy. And Groth, a large, tattooed, rough-around-the-edges type, possesses the biggest serve in the game.

The "Queue up early" match of the day

Without a doubt, Dustin (Dreddy) Brown of Germany against former Australian Open finalist and top-10 player Marcos Baghdatis of Cyprus.

Brown made a splash at last year's Wimbledon not just because he defeated former champ Lleyton Hewitt, but for his eye-pleasing game, his dreadlocks and his showmanship. Baghdatis also can be a showman, even if his career has taken a downward turn. This one is unlikely to disappoint.
