I follow the Brewers very closely. I listen to all their games on the radio and tonight won't be any different. So I believe I am better qualified than most people to speak about this game.
Putting aside the OP's original comments, I give a very small edge to LAD in the betting line. There are a couple of things going for them. 1) Kershaw, along with Cole Hammels IMO, is the best pitcher in baseball. His stuff is down a bit from last year but it is still at at a very elite level. Gallardo, who use to be among the pitching elites, is no longer a reliable starter. His BB/9 is out of this world (4.34). Almost 2 more BB this year than last year and nearly 1 BB more than his career. Plus, if you look at the advanced metrics, you see that he is down in virtually every meaningful category whether it be his first-pitch strikes, getting batters to swing and miss, etc... Now, you might ask, is Gallardo doing anything different this year compared with last year? And the answer is not really. He is still throwing his 3 main pitches (fastball, slider, and changeup) at the same rate he was last year. Just his stuff has not been good and he has been pitching with runners on base all the time. Now the upside for Gallardo is that he is starting to put together some pretty good starts in a row and he is not facing STL and he should regress back to his career numbers. But personally, I don't trust his stuff right now. 2) MILW is fielding an overall very poor lineup these days with a minor league catcher just called up (Martin Maldonado) and Nyger Morgan (who has amazingly 0 RBIs), Rickie Weeks (batting in the .150's), Cody Ransom (replacement level player), Carlos Gomez (a very weak offensive player), etc... In fact, I trust Gallardo with a bat more than 4 of those players I just mentioned. And while LAD is not fielding murder's row, they still have Loney, Kemp and Either a slightly better combination than Hart, Braun, and Ramirez.
Given the edge in pitching and hitting, I made LAD around -160 before it came out. Most of the sharp money is probably backing Gallardo, but I have not seen enough consistency in Gallardo's starts to back him over Kershaw on the road. I don't blame people if they like MILW tonight, but I just don't see it. Kershaw handles righties almost as well as he does lefties and that should neutralize Hart, Braun and Ramirez. Whereas Gallardo has weaker numbers against lefty hitters (i.e. Loney, Either, Abreu, Herrara, etc..).
I recommend a play on LAD on anything < -160 tonight.
