Kirilloff is batting .067 vs left handed pitchers; Larnachis batting .212 against right handed pitchers which he has faced all most 3 times as often as left handed.
Miranda at this point seems to be the real deal with a bat but none of them have excelled in the field and both Kirilloff and Larnach do not have strong arms, while they are fighting for the left field position.
Only Miranda is a threat to Sano, and unless you have a crystal ball , no one here has any idea how well he will do after he returns, or how well any of these rookies will be doing two months from now.
A covey of posters here are trade happy and some of them may end up being traded because they end upbeing better than average.
