Wainwright threw seven innings and gave up no runs with six strikeouts. It was his 12th quality start of the year and he now sits with 97 strikeouts on the season.
He also has a 2.18 ERA (fourth-best) and 1.01 WHIP (seventh-best).
Considering all the facts, does Wainwright now have the edge to start for the NL in the All-Star Game?
So, who deserves it?
Corbin has the most wins (nine) of any starter with no losses. His 2.28 ERA ranks sixth, while his 1.07 WHIP ranks 11th. Strikeouts haven't been his strong suit (only 67), but he does have 11 quality starts.
What has hurt Corbin is that two of his last three starts haven't exactly been his best.
If he does well during that stretch, then he'll be back in the conversation. For now, you can consider him out of the discussion.
Zimmermann is the biggest surprise on the Nationals, especially considering the starting staff includes Gio Gonzalez and Stephen Strasburg.
However, both have disappointed and Zimmermann has been a bit of saving grace for the starting rotation.
He has a record of 9-3 with a 2.00 ERA (second best) and a league-best 0.89 WHIP. Like Corbin, Zimmermann has a low strikeout total (61), but he still gets guys out.
His May 29 start against the Baltimore Orioles was his only hiccup of the year as he gave up seven earned runs. Outside of that, he's allowed no runs four times and 1-2 runs seven times.
If that's not consistent, I don't know what is.
Zimmermann deserves a lot of consideration, but his low strikeout total might be what keeps him from being the starter for the NL.
Some fans hope that Clayton Kershaw will also get some discussion as the starter, but with only five wins thus far, he won't get the start.
While you can place the majority of the blame on the Dodgers offense for their lack of run support, Kershaw's chances don't look good. It's the same reason why Seattle's Felix Hernandez has never started an All-Star Game.
For now, Wainwright has the edge in wins, strikeouts, WHIP and ERA.
Of course it could all change over the course of the next few weeks, but if the All-Star Game starter were to be decided today, Wainwright would have to get the nod.
