Erik Miller made a splash in his 2026 Cactus League debut on Friday, striking out the side in a scoreless inning. The SF Giants' lefty reliever, who had been sidelined by a back issue, is back just in time for Opening Day.
As spring training kicked off, the left side of the Giants' bullpen was seen as a significant strength. With Miller, Sam Hentges, and Matt Gage all having success against left-handed hitters, the team seemed well-positioned. Typically, this kind of situational leverage can secure a bullpen role, but the Giants might need more than just situational contributions from Miller and Hentges this season.
Hentges, one of the few relievers the Giants signed to a major league deal in the offseason, faced his own set of challenges. After only 25 appearances in 2024, he underwent season-ending shoulder surgery, followed by knee surgery last August. With no appearances yet this spring, Hentges is unlikely to be ready for Opening Day.
Miller, on the other hand, missed the latter half of last season due to an elbow injury. The bullpen landscape was quite different when he last took the mound in a regular-season game for San Francisco.
Tyler Rogers and Camilo Doval were handling the eighth and ninth innings, while Randy Rodríguez was utilized in various roles. Miller primarily served as the high-leverage option against left-handed hitters, delivering a solid 1.50 ERA over 36 outings.
Despite his effectiveness, his strikeout (6.6 SO/9) and walk rates (6.0 BB/9) showed room for improvement. However, he held lefty hitters to a .578 OPS, excelling in those matchups.
This season, the Giants may need Miller to step into a larger role. With the bullpen hierarchy still in flux, Ryan Walker is expected to start the year as the closer. Although he struggled in that role last season, the Giants are optimistic about a bounce-back performance.
Miller might be called upon as a high-leverage arm this season. While the Giants haven't finalized their strategy for getting the ball to Walker with the lead, Miller's skillset makes him a strong candidate for those crucial innings. However, his control remains a key concern.
Friday's performance was a promising start for Miller. Although his fastball velocity was slightly down from last year, he still has time to ramp it up before the season kicks off.
