If Jose Reyes is sidelined with his latest oblique injury, 20-year-old Ruben Tejada could get an extended look at shortstop. 

He hasn't shown much as a hitter, but what about his fielding? Well, Tejada made 30 errors in 131 games for Class A Port St. Lucie  in 2008. He cut that to 18 in 120 games at  AA Binghamton in 2009. This season, he had eight in 58 games at AAA Buffalo before being called up.

With the Mets, he has three errors at second base in 32 starts and one at short in 13 starts.

To compare, Derek Jeter leads the majors with fewest errors (5) by a shortstop. The Phillies' Jimmy Rollins was the 2009 leader with just five in 155 games.
