I think if they're 10 games under .500 at the All Star break, sell, sell, sell.
They may need to take a step back, shed some salary if possible, get younger b/c you're still will have a solid core, but you can't pay $20+M for replacement level players.
Schwarber and Castellanos are barely above replacement b/c their fielding is so bad they have to be .850+ OPS to have real value. Same with Hoskins at 1B. Everything went right last year down the stretch, but depending on career offensive seasons is probably not a viable strategy.
Castellanos averaged about 2.5 WAR in his peak years, what did they expect in his 30s?
Schwarber about 2.2 WAR
JT is off relative to last season, but I expect a little bounce back, but at 32, his offense will probably gradually decline and those 6 WAR seasons will be 3-4 WAR seasons, and less if they go to electronic strikes.
Bohm will be 27 in August, I'm afraid this is it, maybe one or two 2 WAR seasons
Sosa RC+ 104, 82, 82, at 27 running out of time to make any sort of jump
Stott is 25, still adjusting to 2B so expect defensive improvement, his hit tool is a middle IF profile, he's still learning on the job but probably better suited to the #2 slot, but at least there's some upside left.
Turner is better than he looks, I doubt he'll ever had a stretch like his last three years, but I also doubt he's a RC+ 72 player - if he just bounces back to RC+ 100 he's a 4 WAR player until his defense declines.
Clemons is at least worth a shot, his numbers so far are similar to what he put up in AAA last year, he's part of a group of players (Dunn, Ellis, Podkul, Roberts) the Phillies have picked up who lost a lot of PA to COVID and being bounced around - good long shot bets on 25-26 year olds having the light go on with a full season of AA/AAA play.
Which also brings up Song, if the team continues to struggle, they should find a spot for him to keep his rights. The last spot in the pen is fine for a team ten games under .500.
Ortiz is the most intriguing prospect in the system, after years of 30+% K rates, he's suddenly posting a 15.0%/20.6% BB/K ratio and his ISO is way up - SSS of 107 PA but he's only 24, maybe the light has gone on.
Muzzioti 204 PA, 7.4%/11.8%, BABIP .398, ISO .128, that .358 BA might be inflated, but still impressive.
Keep an eye on Matt Kroon, less than a 1000 PA due to injuries and COVID at 26, having a breakout season at Reading.
Until the organization fills out, they need some "older prospects" to emerge to add cheap depth and not rush the "real" prospects like Rojas, De La Cruz and Wilson.
