The three replacements set to turn the season around are: Josh Satin, whose .912 OPS at Triple-A Las Vegas is very good, and actually better on the road (.926 OPS) than home (.895 OPS). Sounds like he’ll play first base regularly, where his defense isn’t great.
There’s also Josh Edgin, who has a 5.91 ERA at Triple-A, but hasn’t been scored upon in his last four outings, and Collin Cowgill, who homered on Opening Day, but has a .791 OPS at Las Vegas, which isn’t very impressive. He does have six multi-hit games in his last 12.
But no, if Zack Wheeler is not the savior, these guys probably aren’t, either.
