MESA, Ariz. -- George Kottaras hit a three-run double in the fourth and a two-run double in the fifth to lift the Brewers to a 10-2 victory on Wednesday over the Cubs in front of 11,682 at HoHoKam Park -- the Cubs' highest attendance of the season.

Milwaukee starter Randy Wolf gave up two runs on five hits and one walk over four innings, while striking out four.

Cubs starter Randy Wells cruised through three innings, giving up just two hits. Milwaukee then pounced on Travis Wood in the fourth. With one out, the Brewers loaded the bases as Wood walked two batters and hit Mat Gamel with a pitch. Kottaras then cleared them with a double into the gap in left-center. Carlos Gomez reached on an error by left fielder Reed Johnson -- who misplayed the ball -- and Cesar Izturis followed with a two-run double. Wolf followed with a RBI single that chased Wood.

Starlin Castro and Ian Stewart hit back-to-back doubles in the Chicago fourth, and Jeff Baker followed with an RBI single to close the gap to 6-2. The runs were the first off of Wolf after 7 2/3 scoreless innings this spring.
