I understand the principle under which you WANT to alternate lefty and righty in the lineup. You WANT to do that. However, that desire does not trump the general idea that you protect your best hitter in the lineup with a bonafide major league hitter. JD Drew, for all his warts, comes to mind. Lavarnay has a .553 OPS against right handed pitching in his brief ML career. The starter in the game was a righty. Forget alternating L and R. You cannot hit Lavarnay with a .553 OPS against righties 5th in the order. Can. Not. That is exactly the kind of thing a manager is paid to think about. Allowing gonzalez to be intentionally walked 3 times is a miserable failure of a managerial decision.
And then you have to pinch hit for him in the 9th. Salty may be dinged up and not able to catch 9 innings, but he could sure pinch hit. If he gets a hit and the game goes longer, you figure it out. You don't go quietly with Lavarnay there.
And for all the complaints about both Drew and Crawford, they are both better against righties than Lavarnay. Crawford, even THIS year has an OPS against righties of over .750. Drew is at .650. Salty at .630. Lavarnay at .550.
Hell, Scutaro's OPS against righties is .750. Even Aviles OPS against righties is .600. The guy hitting 5th had the worst OPS against righties in the entire lineup.
That was, simply put, a horrendous series of moves by Francona. Its almost like he didn't realize Lavarnay is very good against lefties and crap against righties. That seriously can't be the answer.
