If they want to try the trade route again, without giving up crazy dollars (i.e., just for a rental), here's a few guys they could look at:
Pat Neshek (Phi) - 36 years old
- 2017: 24.0 ip, 0.75 era, 2.33 fip, 0.79 whip, 8.3 k/9
- last six seasons: 2.56 era, 3.48 fip, 0.98 whip, 8.1 k/9
Joaquin Benoit (Phi) - 39 years old
- 2017: 23.2 ip, 4.56 era, 4.52 fip, 1.18 whip, 8.0 k/9
- last five seasons: 2.37 era, 3.32 fip, 1.00 whip, 9.5 k/9
Ryan Madson (Oak) - 36 years old (more than just a rental because his contract runs through 2018)
- 2017: 24.2 ip, 2.55 era, 2.80 fip, 0.97 whip, 9.5 k/9
- last three seasons: 2.83 era, 3.45 fip, 1.10 whip, 7.8 k/9
Drew Storen (Cin) - 29 years old
- 2017: 27.1 ip, 2.30 era, 3.49 fip, 1.21 whip, 7.9 k/9
- last four seasons: 3.07 era, 3.25 fip, 1.15 whip, 8.7 k/9
Jim Johnson (Atl) - 34 years old (contract runs through 2018)
- 2017: 27.2 ip, 3.58 era, 2.19 fip, 1.01 whip, 9.8 k/9
- last three seasons: 3.74 era, 3.05 fip, 1.27 whip, 8.4 k/9
Obviously these are, except Storen, older guys and all are at the end, or near the end, of their contracts, and all are playing on bad teams. But all of them have a history of being pretty good and are pitching well thus far this season (Benoit excepted, but he's been really good the past 5 seasons). I'd be nervous dealing away much of significant value for any of them, but I don't know what use Philly would have, for example, for Neshek or Benoit, given their age, contract situation, and how horrible Philly is. A decent minor league piece might be sufficient to pry either of them from the Phillies.
