SCOTTSDALE, Ariz. –The Cubs held on to beat the San Francisco Giants 5-4 on Tuesday and are now 4-1 in road games and 4-1 against National League opponents.

The good: Despite relying heavily on a fastball, Chris Volstad still pitched three scoreless innings, allowing two hits. Volstad has now pitched six scoreless innings in two outings this spring as he tries to stake a claim to one of the open spots in the rotation.

The bad: Bryan LaHair didn’t have much luck in a game started by another left-hander. LaHair struck out all three times he came to the plate and now has a .150 batting average (3-for-20) this spring with seven strikeouts. Andy Sonnanstine gave up three runs on five hits in one inning of work, but one hit came on a bunt and another when Blake DeWitt hesitated on a throw from third base.

Outside the box: Anthony Rizzo still figures to be destined for Triple-A Iowa, but he’s making everybody stand up and take notice. Rizzo came on as a replacement for LaHair at first base and hit a two-run home run, his first in a Cubs uniform. He also smothered a ground ball at first on an in-between hop in the ninth inning to help preserve the victory.

Up next: Cubs right-hander Randy Wells (0-0, 0.00) will get the start Wednesday against Brewers left-hander Randy Wolf (1-0, 0.00) in the 3 p.m. CST start from HoHoKam Park.
