Singleton among Houston prospects with big day

While Astros fans at the big league level are getting a taste of what the farm system can produce in the form of George Springer currently, there was plenty of action on Saturday to whet the appetites further for those hungry for more.

The apparent next in line for a callup, first baseman Jon Singleton, has continued to make Triple-A Pacific Coast League pitching look like batting practice. The No. 48 ranked prospect on MLB.com's Top 100 list and No. 4 on the Astros' Top 20 has been on an absolute tear, especially with the long ball. On Saturday in Memphis, Singleton homered and drove in three runs in a 6-2 Oklahoma City win over the Redbirds.

The long ball was the sixth Singleton has hit in the past 10 days. He now leads all of Minor League Baseball in RBIs with 23, and he's tied for second in home runs with seven. He's tied for the lead in extra-base hits (14), while he's second in total bases (52) and third in slugging percentage (.776). In his last 10 games, Singleton has hit .409/.469/.955 with six homers and 16 RBIs.

Singleton is far from the only Astros prospect who made some noise on Saturday. There was plenty of action to watch down in the Class A Advanced California League as well.

No. 1 Astros prospect (No. 8 overall) Carlos Correa went 3-for-3 with a double, a triple and two runs scored. The former No. 1 overall Draft pick, hitting third in the Lancaster lineup, is now hitting .281/.338/.469 over his first 16 California League games.

His offensive worked helped support another fine pitching performance by No. 9 prospect Vincent Velasquez. Last week's Pipeline Pitching Prospect of the Week went five shutout innings to improve his record to a perfect 4-0 on the season. Velasquez gave up just one hit and three walks while striking out four. The 2010 second-round Draft pick now has a 1.29 ERA over 21 innings, having allowed just seven hits while striking out 23.
