SAN FRANCISCO -- Clayton Kershaw playfully took ground balls at shortstop off the bat of third-base coach Tim Wallach during batting practice Wednesday afternoon at AT&T Park.It was a bit awkward since he's a left-handed thrower, of course, but Kershaw scooped several balls up the middle and shoveled to second using his glove. He went into the hole, spun and made a nice, firm throw on the money to Dee Gordon.It gave the impression that, should every other player on the Los Angeles Dodgers' roster capable of playing shortstop go down, he could probably do it.
