Alex Wood

The Dodgers have announced that lefty Alex Wood will “undergo an arthroscopic debridement” of his pitching elbow. The southpaw is expected to miss eight weeks after the surgery is complete, per the announcement.

Doing the math, things don’t look terribly promising for a return in 2016. The team’s estimate would put Wood back in action in mid-to-late September, and that’s before considering a full rehab build-up and factoring in contingencies. A post-season return may be hypothetically possible, but that might be an aggressive assignment.

Wood had been building back after being diagnosed with an elbow impingement, with some optimism being expressed recently, but evidently some recent development led to the change in plans. It comes at an inopportune time for a Dodgers team that also lost another starter returning from injury — fellow southpaw Hyun-jin Ryu — to another malady. And that’s before considering the most important lefty of all, Clayton Kershaw, who doesn’t have a timetable to return from his back issues after a recent throwing session didn’t go well.

Wood, 25, had worked to a 3.99 ERA in 56 1/3 innings on the year, but showed promise for more with a rising strikeout rate (9.9 K/9). With a healthy 53.0% groundball rate mixed in, Wood checked in with rather excellent ratings from ERA estimators. He was carrying a 3.27 FIP, 3.31 xFIP, and 3.52 SIERA.

There’s been plenty of discussion about what Los Angeles might do at the trade deadline, though we’ve heard relatively little in terms of clear connections to specific targets. The organization already added righty Bud Norris to shore up the rotation, but the loss of Wood, the continued uncertainty surrounding Ryu, and an increasingly concerning situation with Kershaw may heighten the Dodgers’ desire to add a major starter.

At present, the Dodgers sit 4.5 games back of the Giants in the NL West and lead the Wild Card race. That’s not a bad spot to be in at all, but the club will need to be firing with all cylinders to keep pace in the division — or, if that fails, to hold off some strong pursuers to qualify for the play-in game.

For Wood, the continued absence comes at a particularly unfortunate time. He is set to qualify for arbitration for the first time after the 2016 campaign, but now is destined to have only a partial-season platform. Though his success and prior innings tallies will help boost his earnings, he’ll surely receive far less than he would have with a healthy year.

The Dodgers announced tonight that an MRI on the left arm of starter Alex Wood has revealed a posterior elbow impingement, which will require four weeks of rest (Twitter link). Per their announcement, he’ll be reevaluated at that time. With a layoff of nearly a month from throwing, Wood seems like a lock to require a minor league rehab assignment before returning, so an absence of at least six weeks (through the All-Star break) seems like a reasonable floor, and the potential for him to miss more time than that certainly exists.

Wood, 25, had rounded into form after a slow start with the Dodgers to open the year. Over his past six outings, a span of 35 1/3 innings, he’d worked to a 2.80 ERA with a scintillating 50-to-8 K/BB ratio and a 43.2 percent ground-ball rate. Wood’s unorthodox delivery has led some to tab him as an injury risk in the past, though this is the first time he’s landed on the Major League disabled list with an arm injury (or with any injury, for that matter). Last season, he totaled 189 2/3 of 3.84 ERA ball between the Braves and Dodgers, who acquired him from Atlanta in the much-maligned Hector Olivera trade.

The Dodgers had already placed Wood on the disabled list and brought Julio Urias back from Triple-A prior to the MRI, and it’ll be Urias who starts in Wood’s place for tomorrow’s matchup against the Cubs. Wood joins left-handers Brett Anderson and Hyun-jin Ryu as well as right-handers Brandon McCarthy and Frankie Montas as injured rotation options on the Dodgers’ disabled list. With him on the shelf, Los Angeles will lean on Clayton Kershaw, Scott Kazmir, Kenta Maeda, Mike Bolsinger and, presumably, Urias in the rotation for the foreseeable future. Other alternatives at the Triple-A level include Ross Stripling, Carlos Frias and Zach Lee.

The Dodgers’ rotation entered play today with the third-best ERA of any team in the Majors, though that mark is skewed to some extent by Kershaw’s dominance. As a collective unit they’ve posted a strong 3.41 ERA, but non-Kershaw starters have provided skipper Dave Roberts and his staff with a more pedestrian 4.14 ERA. The Dodgers clearly have a number of starters that could return from the disabled list to bolster the middle and back-end of the rotation, though given the uncertainties permeating the staff, the top-heavy nature of the rotation and the front office’s active nature, it shouldn’t come as a shock if the Dodgers are connected to potential rotation upgrades on the trade market this summer.
