Saturday's streaking and slumping starting pitchers

Streaking

Jordan Zimmerman, Washington Nationals (7-6, 2.31 ERA)
There hasn’t been a more consistent starter in the month of July than Zimmerman. He hasn’t allowed more than one earned run in each of his last six starts and boasts a ridiculous 0.87 ERA for the month. It’s hard to believe he won’t continue to dominate in his next outing against the ice-cold Brewers. 

Johnny Cueto, Cincinnati Reds (12-5, 2.23 ERA)

Cueto has the lowest ERA in the NL and has picked up wins in each of his last three starts. At this point in the season, Cueto has to be considered as one of the frontrunners for the NL Cy Young Award. He has a chance to continue that momentum against the struggling Rockies.

Slumping

Henderson Alvarez, Toronto Blue Jays (6-7, 4.61 ERA) 

With fireballer Brandon Morrow on the mend, Alvarez could get the boot from the rotation if he doesn’t have a strong outing against the Tigers. Alvarez allowed seven runs on eight hits over 5 2-3 innings pitched in his last start against Boston, but somehow walked away with the victory thanks to a disgraceful performance from the Red Sox pitching staff. He’s allowed 14 earned runs in just 17 innings in July.

Jon Lester, Boston Red Sox (5-8, 5.46 ERA)

Lester’s last three starts have been an absolute disaster. The lefty got booed off the mound at Fenway Park after the Blue Jays roughed him up for 11 runs in just four innings Sunday. His previous two starts against the White Sox and Yankees were equally as dreadful. Add up Lester’s July numbers and the results are staggering. Hold your breath - 22 earned runs and a 10.42 ERA in just 17 innings pitched.
