Dodgers trade for Mets’ Rule 5 Draft selection Seth Rosin, probably see him as a reliever


The Dodgers didn’t take anybody in today’s Rule 5 Draft, but they did trade a PTBNL for Seth Rosin from the Mets, who the Mets plucked from the Phillies.

The Mets have traded right-hander Seth Rosin — their selection in this morning’s Rule 5 Draft — to the Dodgers, tweets’s Ken Gurnick. GM Sandy Alderson had told reporters (including ESPN’s Adam Rubin) earlier this morning that he had worked out a deal to send Rosin to another team for a player to be named later (Twitter links).

The PTBNL probably won’t be a significant piece, or at least I hope not, since Rosin looks to be a speculative bet, at best.

Last year, Rosin posted a 4.33 ERA in AA, primarily as a starter. He struck out just 96 in 126.2 innings, but kept in control, walking only 35. Mediocre performance, so why take the 24-year-old? Probably to try him as a reliever, where he posted strikeout rates of 9.9 and 9.4 per nine in 2012 and 2011.

I actually had watched Rosin in 2012 in the Cal League, and as a starter, Rosin is 91-92 with an average slider and a fringe change, not exactly the profile of a successful prospect. But as a reliever he can hit 93 consistently and can touch 95. Then he can scrap the change and focus on the slider. At 6’6″, Rosin has a deeper release point, so the velocity plays up and he gets depth on his fastball.

Update: John Sickels sees him as a reliever as well.

Rosin is subject to the Rule 5 Draft rules, so he’ll have to remain on the Dodgers’ roster the whole season in order to be kept. So while he’ll be an intriguing Spring Training addition, he’s also one that’s unlikely to make the Opening Day roster, much less stay with the team the whole year. But what’s a $25k loss to Mark Walter, right?
