Presented here are the top 10 pitcher game scores from weekend series, May 4-6, by pitchers who appear in the 2012 Baseball America Prospect Handbook.

• Twice this season Jake Odorizzi has finished a Double-A start with 11 strikeouts and one walk. Though he gave up a run to Tulsa on Saturday, game score sees that start as a better effort—if only slightly so—than his April 23 one when he shut out Springfield for seven innings but allowed four hits. In his last three starts, Odorizzi has notched 26 strikeouts, four walks and 11 hits allowed while allowing four runs in 20 1/3 innings.

• Perhaps no Double-A pitcher has been as efficient this season as Harrisburg lefty Danny Rosenbaum, who in his last four starts has allowed a mere two runs and 21 baserunners in 32 innings. He leads the Eastern League in ERA (0.81), innings (44 2/3) and WHIP (0.69).

• The 49th pick in the last year's draft, Giants righy Kyle Crick has struck out eight in consecutive starts for Augusta, during which time he hasn't allowed a run over 10 innings.

• Toledo lefty Andy Oliver didn't allow his first hit to Columbus on Saturday until the seventh inning. Mud Hens manager Phil Nevin told the Toledo Blade after the game: "That's as good as I have seen him. The stretches where he 'loses his groove' have gotten shorter and shorter the last three outings." In his last three starts, Oliver has allowed just four runs over 19 innings, while striking out 18 and walking 12.

• Last year's top Red Sox pick, righthander Matt Barnes had no trouble adjusting to pro ball in the low Class A South Atlantic League. In five starts he went 2-0, 0.34 (he didn't allow a run until start No. 5) with 42 whiffs and just four walks in 26 2/3 innings. His start on Saturday bodes well for his fortunes in high Class A.

Top Performance By A Prospect-Eligible Pitcher Outside His Team's Top 30

Mariners 20-year-old lefty Jordan Shipers tossed a three-hit shutout for low Class A Clinton against Burlington on Saturday. He struck out six and walked two, improving his season ratio to 26-10 through 39 innings and improving his ERA to 1.62 through six starts. A high school product from Bethany, Mo., Shipers proved very hittable last season in the short-season Northwest League, notching a 4.71 ERA and 1.53 WHIP, but he did sign for $800,000 out of the 16th round in 2010.

Worst Game Score By A Prospect

Rays lefty Braulio Lara surrendered eight runs on nine hits over two innings Sunday for high Class A Charlotte (game score: 3). He allowed 11 of 17 opponents to reach base, while striking out two and allowing a home run. The 23-year-old had allowed three runs total in his past four starts, so this probably is just a bump in the road.

Bill James' game score calculation (Wikipedia entry) rewards pitchers who work deep into games without allowing many runs or hits while providing extra credit for dominance (strikeouts) and control (few walks).
