Presented here are the top 10 pitcher game scores from weekend series, June 22-24, by pitchers who appear in the 2012 Baseball America Prospect Handbook.

• Indians lefthander T.J. McFarland earned a promotion to Triple-A Columbus at the end of May after going 8-2, 2.69 in 10 starts for Double-A Akron. The 2007 fourth-rounder has continued on his back-of-the-rotation trajectory with the Clippers, piling up innings and groundballs, if not strikeouts. The 23-year-old McFarland lowered his Triple-A ERA to 4.22 after his four-hit shutout of Lehigh Valley on Sunday, during which he faced just three batters over the minimum.

• The White Sox pushed Andre Rienzo to Double-A Birmingham when he returned from his 50-game suspension for performance-enhancer use, but the 23-year-old seems no worse for the time missed. Despite missing nearly two months, the Brazil native has allowed only one run on seven hits in his first 11 1/3 innings for the Barons, while striking out nine.

• Read about the pitching heroics of low Class A hurlers Adalberto Mejia, a Giants sleeper; Noah Syndergaard, a physical, hard-throwing righty in the Blue Jays system; and Kyle Crick, who could be the next big Giants pitching prospect.

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

High Class A Lynchburg righthander Aaron Northcraft kicked off the weekend in style, tossing a seven-inning no-hitter on June 22 in the second game of a doubleheader versus Salem. His gem (85 game score) was the first single-pitcher no-hitter in the minors this season. The 22-year-old Northcraft struck out 10, walked two, hit a batter and dealt with one other baserunner, the result of an infield error. A Braves 10th-round pick out of high school in 2009, Northcraft ranks second in the Carolina League (to Myrtle Beach's Cody Buckel) with 78 strikeouts.

Worst Game Score By A Prospect

Rangers righty Barret Loux went 5-0, 1.63 and allowed five runs total in five April starts for Double-A Frisco, but he's logged a 5.21 ERA in nine starts since then, an average stoked by a nine-runs-in-three-innings performance on Friday. In that start, he allowed eight hits, including a homer, while striking out four, walking one and taking his first loss of the season (game score = 10). Pitching for the Texas League Southern Division-leading RoughRiders has its advantages, however, as the 23-year-old Loux has picked up wins in 11 of his 14 starts this season despite ranking 16th in the league with a 3.87 ERA.

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).
