Riley O'Brien made the ASG over Trevor Megill as well.
Megill - 2.76 ERA, 2.72 xERA, 1.89 FIP, 28 saves
O'Brien - 4.14 ERA, 4.95 xERA, 3.96 FIP, 37 saves
I think it's one of the reasons why you should take into consideration underlying stats for the ASG because a lot of guys can have flukey half seasons and make the ASG. Now just because you had good underlying stats doesn't mean you will continue it in the second half but I think someone with good underlying stats is more likely to carry over success to the second half than a guy playing way above his underlying stats.
