Ethan Small To Miss Several Weeks With Oblique Strain

The Giants announced to reporters, including Susan Slusser of the San Francisco Chronicle and Maria I. Guardado of MLB.com, that left-hander Ethan Small has a right oblique strain. Though the strain is described as moderate, the club nonetheless estimates that the lefty will be out for “several weeks.”

Small, 27, is a former first-round pick of the Brewers who came over to the Giants in a trade last month. He only has 10 1/3 innings of major league experience thus far, with an earned run average of 8.71, but has impressed in the minors. Last year, the Brewers moved him from a starting gig into a primary relief role. He tossed 51 innings at Triple-A last year with a 3.18 ERA, striking out 28.5% of batters faced in the process. His 11.2% walk rate was a bit concerning but it was encouraging season nonetheless.

Small wasn’t slated to be the most important part of the San Francisco bullpen but he was arguably the club’s #2 lefty behind Taylor Rogers. The only other southpaw reliever on the roster is Erik Miller, who doesn’t have the first-round pedigree of Small and has yet to make his major league debut.

The move will add another question mark to a San Francisco pitching staff that has plenty. They have long known that they would be starting the season with starters Alex Cobb and Robbie Ray on the injured list, but this spring has seen each of Keaton Winn, Tristan Beck and Sean Hjelle deal with various ailments. Winn seems like he’ll avoid missing any time but Beck is already on the injured list and Hjelle is likely to join him.

The bullpen consists of a strong group of four for the high-leverage work, with Camilo Doval in the closer’s role, backed up by Rogers, his brother Tyler Rogers, as well as Luke Jackson. Beyond that, none of the relievers on the roster have much experience. Miller and Randy Rodríguez haven’t pitched in the big leagues yet while Small and Ryan Walker have less than a year of service time.

RosterResource currently estimates that non-roster invitees Spencer Howard and Daulton Jefferies will crack the Opening Day bullpen. Jefferies has missed most of the last two seasons as he underwent both thoracic outlet syndrome surgery and Tommy John surgery in 2022, while Howard has a 7.20 ERA in his 115 big league innings and a 4.43 ERA in Triple-A.

There’s a lot of question marks in a bullpen that could be important, considering their rotation isn’t overflowing with certainty right now. Ace Logan Webb figures to be backed up by Kyle Harrison, who is a notable prospect but with seven big league starts to his name. Longtime reliever Jordan Hicks is going to attempt to move to the rotation. Winn has less than 50 innings under his belt. Prospect Mason Black might crack the Opening Day rotation to make his major league debut.

There are many moving parts and the overall structure of the staff will likely be an ongoing storyline in San Francisco this year. If the club has interest in bolstering their pitching staff with external additions, there are options still out there. Brad Hand, Jarlín García and Aaron Loup are lefty relievers that are still unsigned here in mid-March and likely won’t command huge salaries. The Giants have Amir Garrett and Juan Sanchez in camp as non-roster invitees. Garrett has thrown 3 2/3 innings in the spring with four walks and six earned runs allowed, wherehas Sanchez has tossed six frames with only one earned run crossing the plate, striking out eight with no walks given out.
