Tonight at 10:05 p.m. ET, the Kansas City Royals (41-28) and Oakland Athletics (34-41) open up a three-game weekend series live from the O.co Coliseum in Oakland.

Kansas City has won two of its last three games as it continues a six-match road trip while Oakland has won five consecutive contests as it opens up a 10-game homestand.

The Royals took two of three from the Mariners in Seattle from Monday-Wednesday while the A's swept away the Rangers in Texas from Tuesday-Thursday.

Edinson Volquez (7-4, 3.33 ERA) toes the rubber for the Royals while the A's counter with Jesse Hahn and he is 5-5 with a 3.40 ERA thus far this season.

Despite not having any strikeouts and allowing four runs in 5.1 innings last time out, Volquez is coming in on the heels of a victory over the Boston Red Sox.

Hahn, who has allowed just three homers this season, is coming in off of a performance where he allowed just one run and four hits in 7.2 innings against the Los Angeles Angels on Saturday. He's allowed one earned run in three of his four starts in June.

This is the first meeting between these two teams since a controversial series from April 17-19 that saw the two clubs engage in a weekend of beanings, bench clearings, warnings, ejections and led to a fine and a suspension following Brett Lawrie's hard slide in Game 1.

Volquez faces an Athletics lineup that is paced by catcher Stephen Vogt, who owns a team-best .308 batting average and leads the club with 13 homers. Vogt also is first in the American League with 53 RBI, which is fourth overall in the MLB.

The Royals counter with a roster that is carried by third baseman Mike Moustakas, who is fifth in the AL with a .328 batting average and has seven homers and 30 RBI. Centerfielder Lorenzo Cain is tied for third in the AL with 14 stolen bases.

As far as the standings go, Kansas City enters Friday atop the AL Central with a 3.5-game lead over the second-place Minnesota Twins while Oakland is in fourth in the AL West, nine games behind the division-leading Houston Astros.

The Royals and A's open up a three-game weekend set live tonight from the O.co Coliseum in Oakland.
