In Europe, it's very common for soccer matches to be played in empty stadiums after violent clashes between fans, but it's something we've never seen in the history of Major League Baseball. For the first time ever, the Orioles will host the White Sox in a game at Camden Yards that will be closed to fans. I'll take the visitors in this historic contest.

Here are my keys to the game:

1. Pitching - Jeff Samardzija will be on the mound for the visitors, and he's starting to look like the pitcher Chicago paid for in the off-season. Samardzija (1-1, 3.33 ERA) tossed six scoreless innings in a shutout win over Cleveland in his latest outing. The Orioles will counter with Ubaldo Jimenez, who is coming off a loss to Toronto in his last start.

2. Baltimore Bullpen - Chicago's bullpen was a real weakness last year, but the Sox have turned things around with one of the best bullpens in the American League so far. That's not the case for the Orioles, who rank better than only Cleveland.

3. X-Factor - Jimenez was 3-6 with a 5.52 ERA in 11 starts in Baltimore last year, and he was an awful 1-8 with an 8.82 ERA in days games in 2014.

Selection: This is a play on the Chicago White Sox.
