Towering homer from Castro leads Cubs

MESA, Ariz. -- The Cubs wrapped up their spring training slate in style by cruising to a 5-3 victory over a split Brewers squad on Tuesday at HoHoKam Park.

Starlin Castro's mammoth home run in the bottom of the first inning gave the Cubs a lead they would never relinquish and capped a very good spring from the Chicago shortstop. Castro, who batted .311 in the Cactus League, crushed a no-doubter off the top half of the left-field scorebard behind the Bermuda-grass hill.

For the Brewers, who held most of their regulars for the night game of their split doubleheader against the D-backs, Scooter Gennett had three hits and third baseman Andy Gonzalez went deep for the only run that would come off the Cubs' lefty Travis Wood.

Wrapping up what was a shaky spring, Wood will at least head to Triple-A Iowa with an outing like Tuesday's under his belt. He lasted six innings and surrendered just that one run on six hits, while striking out four.

Wood's counterpart, Double-A Huntsville's Kyle Heckathorn, wasn't as sharp. The Cubs hit him hard for five runs on eight hits in five innings. He allowed two home runs -- the two-run shot to Castro, and a solo homer in the fifth to Alfredo Amezaga. In the second inning the Cubs added to their lead against Heckathorn by stringing together three consecutive hits. Joe Mather doubled home Reed Johnson, who had singled, and then a Darwin Barney single scored Mather.

Amezaga's first homer of the spring solidified the result for the Cubs, who wrapped up the spring with a 17-16-2 record. Sitting at .500, the Brewers still have a couple games remaining -- Tuesday night and Wednesday afternoon against the D-backs.

Up next: The Cubs ended their Cactus League slate Tuesday and will be in Chicago for an off-day Wednesday before their season opener against Washington on Thursday. The Cubs will send Ryan Dempster to the mound at Wrigley, and he'll be facing Nationals' ace Stephen Strasburg.
