Cubs optioned LHP Zach Rosscup to Triple-A Iowa.
Rosscup was the 26th man for Wednesday's doubleheader and tossed 1 2/3 perfect innings in an appearance. He should get another shot later this summer.
Diamondbacks sent RHP Alex Sanabia outright to Triple-A Reno.
He's now off the 40-man roster. Sanabia, 25, has posted a 9.49 ERA in his first three starts at Reno.
Koji Uehara returned to action on Thursday April 17.
Chase Headley returned to action on Thursday April 17.
Brandon Crawford returned to action on Thursday April 17.
Jon Lester tossed eight strong outings, allowing just one run and striking out nine, in defeating the White Sox on Thursday.
Lester cost himself in the sixth, when he was too slow to get over to first base on Adam Eaton's run-scoring infield single, and again in the seventh, when he failed to handle a pretty easy comebacker. But fielding issues aside -- and his awkward throws to first likely will lose him a game at some point -- he's been outstanding on the mound. He's currently sporting a 29/4 K/BB ratio in 29 innings and a 2.03 ERA. Next up for him is his second start of the month against the Yankees.
Koji Uehara earned a save with a scoreless ninth in his return to the mound Thursday against the White Sox.
Uehara showed his usual velocity in his return from a sore shoulder, but he did give up a single and miss up with a couple of splitters to a dangerous hitter in Jose Abreu with two outs. Fortunately, Abreu didn't take a cut at either of those before grounding out on a better offering. In all, Uehara threw 13 pitches. The Red Sox will likely be especially careful with him for the next few weeks, so if they have another save situation on Friday, we imagine it will go to Edward Mujica.
Chris Sale wasn't involved in the decision after allowing one run in seven innings and striking out 10 against the Red Sox on Thursday.
Sale was dominant for the most part, with the Red Sox crushing two of his very few mistakes. Fortunately, the first didn't hurt him, as Adam Eaton robbed David Ortiz of a homer in the first. The other did, though, as Xander Bogaerts was able to hit one out to left in the sixth. It was the first homer allowed by Sale in four starts this season.
