Kershaw allowed five runs (four earned) on a season-high-tying eight hits in a six-inning no-decision against the White Sox on Friday.
Kershaw has been battling plantar fasciitis in his left foot, although he's insisted the painful condition doesn't bother him pitching. Two weeks ago, the southpaw briefly eliminated between-starts running for conditioning, but he has since resumed the activity.
"He has to keep dealing with it," said manager Don Mattingly. "He's had to modify his workout so it doesn't get worse. He said he doesn't feel it pitching or pushing off [the rubber], but he's changed his routine a little and that sometimes can affect you. It sounds like it's no better, no worse. It's not like it's going away."
The defending National League Cy Young Award winner is 5-3 with a 2.86 ERA. After winning the pitching Triple Crown (wins, ERA and strikeouts) last year, the only category in which he ranks in the top 10 is strikeouts (88 for eighth).
The number that really stands out is 10 homers allowed in 94 1/3 innings, including two to Adam Dunn and Carlos Rios on Friday night. In 233 1/3 frames last year, Kershaw allowed only 15 homers. Left-handed hitters have four homers this year compared to three all last year.
Since pitching a May 19 shutout against the Cardinals, Kershaw has allowed 17 runs in 32 2/3 innings (4.68 ERA).
