3 relief pitcher trades to replace Drew Smith's roster spot

Drew Smith got off to an unbelievable start this season for the New York Mets, not allowing a run in his first 13.1 innings pitched (12 appearances). Since that start, things have been rocky, but the one constant was he stayed healthy, something he had not done in any of his other years in the bigs.

Unfortunately, Smith has found himself on the shelf once again, this time with a right lat strain. The Mets have not given a timeline for his return, but I would assume Smith will be on the IL past the minimum 15 days.

The Mets bullpen was shaky even with Smith healthy and now with him out, the need for bullpen arms is as prevalent as ever.

1) NY Mets trade to replace Drew Smith on the roster: David Robertson

David Robertson is the reliever I want at the deadline the most. He's had a resurgent season in Chicago and wouldn't cost much given his age and the fact that he's a free agent after the season.

Robertson didn't sign with the Cubs until after the lockout, and he wasn't even on a roster for much of last season until Tampa Bay signed him following Tommy John surgery.

The 37 year old has gone 3-0 with a 1.83 ERA in 35 appearances for the Cubs this season. He has converted 14 of his 19 save opportunities and even has eight outings in which he has accumulated more than three outs.

Robertson wouldn't be the closer for this Mets team of course, but he'd be an elite setup man for Edwin Diaz. Adam Ottavino has been excellent, but other than him, it's been hard to find an arm Buck Showalter can trust late in games to set up for Diaz.

Robertson set up for Mariano Rivera back in the day with the Yankees and did a great job with that. His proven success in New York is yet another reason he'd be such a good fit with the Mets.

Robertson spent seven seasons in the Bronx and that meant a lot of postseason appearances. In 33 appearances he has posted a 3.11 ERA, faring well in big moments. Given most of this Mets bullpen has not seen playoff action, it'd be nice to have a seasoned vet to help calm the nerves.

Robertson's price will be cheap, and he'd be the perfect addition to this Mets bullpen.
