Upton scored seven times and was successful on all three stolen base attempts.

NL Player of the Week
Chase Headley, San Diego—The Padres’ third baseman has taken over the National League lead in RBIs.

He also homered four times.
NL Pitcher of the Week
Kris Medlen, Atlanta—The Braves’ young righthander finally saw his 40.2-inning scoreless streak come to an end, but he defeated the Mets anyway, allowing just two earned runs over six innings. The Braves have won Medlen’s last nine starts. For the week he allowed nine hits, two walks and struck out 15 in 15 innings.
