The Phils will approach to their stars' nonperformance is to let them work it out on the field. Sometimes it's better management to sit nonperformers. Not in the Phils' repertoire.
Sosa is an obvious sub for Stott. Sosa is every bit as good a defender as Stott. Likely the best IF on the team, IMHO. The Phils want to keep him as a backup IF, which a team has to have, but he should have been given a shot in LF. Yes, his hitting hit a wall, but he showed incredible talent at the plate with a lot of PT. He could get it back. Been said that he is an IF and not ready to play OF. Didn't stop Dave Roberts from playing an IF in LF against the Phils when his team was running out of hitters. Sure enough, he muffed one. For OF replacment, take your best guess who is going to perform. Things look a lot better w/o Merrifield and Pache.
At the moment Hays looked like he was ready to take over LF, he gets a hammy. They think like Marsh, maybe 2 weeks. Hays sounds eager and confident.
Watch the Phils closely and you'll see how to manage when your entire team slumps at once.
