Madison Bumgarner Won’t Require Surgery

APRIL 28: Bumgarner will indeed not require surgery, but he’s expected to be out for quite some time, as Andrew Baggarly of the Mercury News reports (Twitter links). With some “partial ligament tears” in the AC joint, it is indeed a Grade 2 sprain that will require about two months of rehabilitation followed by a three-or-four-week buildup on the mound.

APRIL 25: Initial evaluations on Madison Bumgarner, who suffered bruised ribs and a shoulder sprain last week in a dirt bike accident, are fairly positive, per Andrew Baggarly of the San Jose Mercury News (Twitter links). Bumgarner’s injured shoulder won’t require surgery and has calmed down to the point where he could begin rehab work on it in the next four to five days, Baggarly adds. While that all sounds encouraging, Bumgarner’s layoff will still be considerable; Baggarly notes that he could be ready to begin throwing off a mound in about two months’ time, and he’ll of course need to then build up enough arm strength to rejoin the rotation.

All told, that timeline seems to suggest that Bumgarner won’t be back in the Giants’ rotation until at least mid-July. Of course, that timeline is dependent both on how his shoulder responds to rehab work and on how lengthy of a rehab assignment he’ll require once he returns to the mound. More clarity on Bumgarner’s timeline may soon become available, it seems, as Henry Schulman of the San Francisco Chronicle tweets that the Giants will give an official diagnosis on Bumgarner tomorrow.

“He’s going to start some light work,” manager Bruce Bochy told reporters (link via Schulman). “It’s going to be slow at first, nothing major. Things have calmed down a little. There’ll be no surgery or anything. We’re going to rehab this.”

The Giants’ rotation without its ace still appears solid, albeit unspectacular, as nominal No. 2 starter Johnny Cueto would be the top arm in most rotations around the league. Cueto will be followed by Jeff Samardzija, Matt Moore, Matt Cain and Ty Blach for the time being, though it’s certainly possible that top Giants prospect Tyler Beede eventually forces his way into the big league rotation mix. That group faces an uphill battle in helping the Giants stay afloat in the National League West, however; San Francisco enters play tonight with just a 7-13 record, and two-plus months without one of the game’s very best pitchers clearly hampers the team’s ability to dig out of that early hole.

On a related note, it seems that the Giants got a bit of good news regarding another member of the rotation. Schulman notes that an MRI on Cain’s ailing hamstring came back clean. The veteran right-hander is expected to make his next scheduled start — a Saturday outing against the Padres.
