Quick Hits: Alvarez, Guerrero, Hahn

Athletics righty Henderson Alvarez has suffered a “setback” in his efforts to return from shoulder surgery, John Hickey of the Bay Area News Group reports on Twitter. Oakland had hoped to plug him into the major league rotation in the coming days, but instead Alvarez is headed for an MRI. The 26-year-old had turned in six solid starts in his minor league rehab assignment, leading to hope that he’d provide a boost to an A’s staff that has largely failed to produce quality results thus far. Alvarez’s prognosis remains unclear at this time.

Here are a few more notes to round out the evening:

• The Dodgers will soon face a decision on utilityman Alex Guerrero, as J.P. Hoornstra of the Los Angeles News Group writes. Guerrero, 29, has begun a rehab assignment after missing time with an injured knee, but it’s not clear at all where he’d fit on the major league roster. While he’s often been discussed as a trade candidate, there are some clear barriers to a deal, even beyond his defensive limitations and a mixed and limited MLB track record. For one thing, he’s owed $5MM for the present season and for 2017. For another, his unusual contract provides that he cannot be optioned without his consent and that he would have the right to elect free agency after any season in which he’s traded.
• White Sox GM Rick Hahn says that he’ll continue not to “leave any stone unturned” in improving the club’s roster, as Bruce Levine of 670thescore.com reports. While it doesn’t seem that Chicago will land Tim Lincecum, and though Hahn wouldn’t address his situation directly, the GM did say that he believes the presence of pitching coach Don Cooper and trainer Herm Schneider help the organization when it seeks to woo bounceback candidates. Of course, as Hahn implicitly acknowledges, there may well come a point this year where the Sox find a need to do something more to address the back of the rotation. “It would be too good of an opportunity to squander to not try to do everything in our power to put the club in a position where Chris Sale, [Jose] Quintana, [Carlos] Rodon and others get to perform on the biggest stage in October,” he said.
