Presented here are the top 10 runs created tallies for position players from weekend series, May 11-13. Players must appear in the 2012 Baseball America Prospect Handbook.

• Astros center fielder George Springer homered in four consecutive plate appearances, spanning two games of a Friday doubleheader, and now owns a .350/.389/.700 batting line in 20 home games with high Class A Lancaster. He's the seventh minor league player to homer three times in one game this season. Wouldn't you know that three of those outbursts occurred in the California League? (The other two: High Desert third baseman Steve Proscia on April 19 and Stockton first baseman A.J. Kirby-Jones on April 18.)

• Lost a bit among the organization's plethora of power arms, Diamondbacks third baseman Matt Davidson is gaining serious prospect momentum this season in the Double-A Southern League, which he tops with eight home runs and 19 extra-base hits as part of a .318/.434/.583 batting line through 132 at-bats. The 21-year-old homered twice in a game versus Chattanooga on Sunday (once against Dodgers prospect Chris Withrow) and also went deep on Friday.

• The hits keep coming for Rangers shortstop Jurickson Profar, the 19-year-old uber-prospect who extended his hit streak to 23 games with a single for Double-A Frisco on Sunday. He homered on Friday and smacked three doubles on Saturday to pick up the slack. Profar during his streak has gone 31-for-98 (.316) with a homer, 11 doubles, four triples and a 7-to-18 walk-to-strikeout ratio.

• We singled out Padres second baseman Cory Spangenberg on last Friday's Prospect Hot Sheet, and the 2011 first-rounder appears to have turned a corner in high Class A after a slow start in the California League. He has 18 hits in his last 42 at-bats (.429) for Lake Elsinore while also compiling four doubles, two triples, five steals in five attempts and just three strikeouts.

• While he's batting just .198/.246/.306 with two homers in 111 at-bats for low Class A Clinton, Mariners left fielder Guillermo Pimentel showed signs of life over the weekend by collecting six hits, including three doubles. The 19-year-old's power potential is obvious, but he'll need to curb a high strikeout rate that registers at 31 percent of plate appearances thus far.

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

Padres right fielder/first baseman Cody Decker has mashed 71 home runs in his four pro seasons, and with 13 for Double-A San Antonio this season he's just two away from matching last year's total. The 25-year-old went deep four times over the weekend, batting 6-for-11 with three walks and seven RBIs for the Missions.

Rough Stretch

With his struggles for Triple-A Tacoma this year, Mariners third baseman Vinnie Catricala has struggled to build on a breakout 2011 season. He lowered his season batting line to .203/.258/.259 after going 1-for-12 with five strikeouts over the weekend.

The Bill James-devised runs created metric (Wikipedia entry explains ’02 version) rewards batters for avoiding outs and reaching base safely (on-base percentage) and for accumulating total bases (slugging percentage), two factors that correlate strongly with run scoring, and for obvious reasons.
