Talk of Jonathan Singleton's disappointing season has been greatly exaggerated. The Phillies' high Class A first baseman went 2-for-4 and hit his seventh home run of the season yesterday, bringing his season line to .279/.384/.401 through 78 games. Despite being the Florida State League's youngest hitter at 19, Singleton's on-base percentage is 52 points higher than the league average and his slugging is 18 points higher than a league that's hitting .261/.332/.383 as a whole.

• The Red Sox pulled a surprise by jumping Aruban shortstop Xander Bogaerts from the Dominican Summer League in 2010 to low Class A Greenville in June. Bogaerts has flourished in the South Atlantic League, hitting .253/.339/.515, including a 3-for-5 showing with a double yesterday.

• The Angels drafted C.J. Cron in the first-round this year because of his ability to hit and hit for power. He's done just that as Rookie-level Orem's DH, going 2-for-5 with a home run yesterday, giving him four homers in 12 games and a .365/.441/.654 batting line.

• A high-profile Dominican signing in 2009, Rockies shortstop Rosell Herrera went 1-for-4 and hit his fourth home run of the year yesterday for Rookie-level Casper. Herrera, 18, was one of the top prospects in the Dominican Summer League a year ago and is hitting .300/.371/.575 through 20 games.

• Cardinals 2011 first-round pick Kolten Wong picked up a hit in his ninth straight game, going 3-for-4 with a triple and a home run for low Class A Quad Cities. Wong, 20, is hitting .333/.420/.561 overall through 15 games with the River Bandits.

• A hamstring injury kept Cardinals outfielder Oscar Taveras on the bench for a while early in the season, but he's been one of the best hitters in the low Class A Midwest League when he's been on the field. While his teammate Wong stole the show, Taveras went 3-for-4 with a triple yesterday, extending his hitting streak to eight games and bringing his slash stats to .371/.411/.523 through 35 games.

• Mariners righthander Taijuan Walker has been one of the breakout prospects of 2011 since joining low Class A Clinton in May. Walker, 18, has overpowered hitters with a heavy fastball that reaches the mid-to-high 90s and an above-average breaking ball. Yesterday he became the rare Midwest League prospect to throw nine innings, holding Great Lakes to two runs in a pair of hits and a walk while striking out seven. Walker now has 90 strikeouts in 71 innings and a 2.66 ERA.

• Some scouts thought Rockies righthander Joel Payamps was one of the better value signings of last year's July 2 class. The early returns have been positive for the 17-year-old Dominican, who struck out six in five shutout innings yesterday in the DSL. Payamps has only made four starts, but he's been impressive with an ERA of 0.95, 23 strikeouts and eight walks in 19 innings.
