jackpot - I have no info on Mayers other than what most probably know. He's a 24yr old righty who started the year in AA then moved up to AAA and now gets his MLB debut tonight.
In 9 AAA starts he was 3-3, 2.94 ERA, 1.25 WHIP. Not bad.
He gets a 0 TTF rating based on no MLB record.
Kazmir gets the same 0 TTF rating based on his 1.27 WHIP.
STL is 4 TTF rating points better than LAD offensively (OPS) while LAD's pen is 0.5 TTF rating point better than STL.
There's the obvious risk of backing a guy making his debut, but STL's +3.5 overall TTF rating for this match up puts them just into 2 unit play territory.
I wouldn't classify this as a top play, but a plus money team rated +3.5 (2 units) is worth a close look IMO.
Hope that helps.
Cheers!
