Cubs sent RHP James Russell outright to Triple-A Iowa.
Russell has had a miserable season, compiling a 5.29 ERA and 1.50 WHIP over 34 innings. He'll continue to provide bullpen depth at Triple-A and could get another chance with the big league club before the regular season ends.
Cubs recalled RHP C.J. Edwards from Triple-A Iowa.
The 24-year-old has posted a terrific 2.87 ERA, 1.24 WHIP and 41/17 K/BB ratio over 53 1/3 innings between Double-A Tennessee and Triple-A Iowa. He'll provide an extra weapon out of the bullpen for the Cubs in the final month of the season.
Chris Heston will start for the Giants on Friday against the Rockies in Colorado.
Giants manager Bruce Bochy had given consideration to starting Tim Hudson in his place, but opted to stick with the young right hander. If he has another rough outing though, he could be shifted to the bullpen.
Dodgers purchased the contract of INF Corey Seager from Triple-A Albuquerque.
Arguably, the top position prospect in all of baseball, the 21-year-old will look to add a spark to the Dodgers push toward the postseason over the final month of the regular season. He's slashing .292/.343/.486 with 18 homers and 74 RBI in 124 games between Double-A and Triple-A this year. Seager is starting at shortstop and batting eighth in his major league debut Thursday evening.
Dodgers designated 1B Andy Wilkins for assignment.
He was the roster casualty required to create a spot on the 40-man roster for Corey Seager. If he isn't claimed on waivers, he should continue to provide organizational depth at Triple-A.
