Giants (ss) 13, Brewers (ss) 3

Twenty-year-old prospect Tommy Joseph was supposed to be here just to get an idea of what it’s like to be in a major league spring training camp. But if he keeps playing the way he did today, he may find himself on the 25-man roster come Opening Day.

Joseph went 2-for-3 and clobbered two home runs to lead a San Francisco Giants split squad over the Milwaukee Brewers 13-3 Saturday at Scottsdale Stadium. [box score]

The sample size is small, but the numbers are large for Joseph: 4-for-9 (.444/.545/1.111, 1.657 OPS), 4 R, 2 HR, 6 RBI, 2 BB. This is the guy I was telling you about last November, when I ranked him No. 3 on my “22 Giants Prospects You Need To Know” list. He’s the real deal, folks. Could be better than Posey.

Giants starter Barry Zito pitched three strong innings in his second Cactus League start and allowed just a single to pick up the win.

The Giants’ other split squad fell to the Los Angeles Angels 9-5 at Tempe Diablo Stadium. San Francisco is now 6-3-1 in Cactus League play.

The Giants will face King Felix and the Seattle Mariners tomorrow at Scottsdale Stadium. Left-hander Eric Surkamp (0-1, 8.31) will make his first start of the Cactus League season, taking on 2010 AL Cy Young Award winner Felix Hernandez (0-0, 0.00).

Closer Brian Wilson is expected to make his Cactus League debut tomorrow.

The game can be heard on KNBR 680 AM at 12:05 p.m. (PT).

NOTES: The Giants tallied 16 hits in this game, 12 of which went for extra bases … Pablo Sandoval hit his first home run of the spring, a two-run shot in the third inning. He also doubled. Took him a few games, but it looks like the Panda has found his stroke … Remember when all the talk was about letting slick-fielding Brandon Crawford start at shortstop and hope the rest of the lineup can compensate for his light stick? Well, so far Crawford’s holding his own this spring. He went 2-for-3 with a double, triple and three RBI Saturday to lift his average to .429, in the nine-hole … Thirty of Zito’s 45 pitches went for strikes … Manager Bruce Bochy has decided to wait until a little later in the week to let Freddy Sanchez play second base. He was supposed to play there on Monday, but Boch doesn’t want to rush him … The annual parade of a dozen or so low self-esteemed Dodgers fans who have nothing better to do than show up at the Giants’ spring training home every year and take abuse from Giants fans happened today. Not one of them was wearing a shirt supporting Bryan Stow. Stay classless, Dodgers fans.
