The A’s are seemingly in the hunt for an addition to their bullpen, hears Mark Feinsand of MLB.com (Twitter link). To that end, Oakland was in on Trevor Rosenthal before the Royals traded the right-hander to the Padres yesterday, Feinsand adds.
The A’s bullpen has been a big part of their 22-12 start. Oakland relievers have pitched to a league-best 1.87 ERA and 2.92 FIP this season, with strong contributions from Liam Hendriks, Joakim Soria, Lou Trivino and others. Nevertheless, there’s little harm for the Oakland front office in seeking to lengthen the pen. The club’s starting rotation has been a middle-of-the-road unit. An even deeper bullpen would give manager Bob Melvin more ammunition to mix-and-match on the pitching staff, which could be especially useful in the postseason.
Beyond Rosenthal (who’s obviously no longer a trade candidate), it isn’t clear specifically who Oakland is targeting. There are a host of relievers who look like potential trade candidates, among them Kansas City’s Greg Holland, Baltimore’s Mychal Givens/Miguel Castro and Boston’s Matt Barnes.
