Young stars go deep

Russell Martin, who will be the everyday catcher, and Matt Kemp, who won’t make the team but will be a major-league star one day soon, homered in the fifth and sixth innings, respectively. Kemp’s was a no-doubt, three-run blast deep into the pavilion in left center. James Loney legged out a double, although he might have been out at second if the throw from right field hadn’t been offline. Anyway, with that hit, Loney raised his spring average to .415.
