Teng has impressed the Astros' staff early in spring, giving him a chance to make the Opening Day roster, per Chandler Rome of The Athletic.
EDGE Analysis
Per Rome, Houston has been impressed by Teng's ability to record swinging strikes "with multiple breaking balls". The right-hander was traded to the Astros in late January after posting a 6.37 ERA across 29.2 innings with San Francisco last year. Teng's ability to provide multiple innings out of the bullpen is certainly viewed as an asset, as Houston plans to open the season with a six-man rotation. Their middle relief depth has already been tested, as Enyel De Los Santos (knee) has yet to resume throwing, opening the door for Teng to claim a roster spot.

Teng was traded from the Giants to the Astros in exchange for a minor-league player on Thursday, Robert Murray of FanSided.com reports.
EDGE Analysis
Teng has experience as both a reliever and starter in the majors, and he worked primarily out of the Giants' rotation toward the end of the 2025 season. He still has two options remaining, so there's a strong chance Teng begins the season with Triple-A Sugar Land, though he should contribute to the big-league team at some point in 2026.

Teng allowed two runs on a hit and two walks while striking out six over three innings in a no-decision versus the Dodgers on Saturday.
EDGE Analysis
Teng threw just 39 of 74 pitches for strikes but was able to limit the damage to a two-run home run by Max Muncy in the first inning. The Giants look to be limiting Teng's workload -- he's reached the five-inning mark in just two of his eight major-league appearances this season. He's at a 6.37 ERA, 1.55 WHIP and 39:17 K:BB through 29.2 innings with the big club. Teng could get one more appearance this season, which is tentatively projected to be at home versus the Rockies in the final series of the year.

Teng allowed one unearned run on two hits and a walk while striking out five over four innings in a no-decision versus the Diamondbacks on Monday.
EDGE Analysis
Teng gave up a run in the first inning but generally allowed the Giants to keep things close before the bullpen had a rough night. This was Teng's first appearance in over a week after he allowed four runs on three hits and five walks versus the Cardinals on Sept. 7. The right-hander is now at a 6.41 ERA, 1.61 WHIP and 33:15 K:BB through 26.2 innings over seven appearances (six starts) in the majors this season. The Giants' rotation has been in flux recently, but Teng would next be available to pitch on normal rest in the back half of this weekend's four-game road series versus the Dodgers.

Teng (2-4) took the loss against the Cardinals on Sunday, allowing four runs on three hits and five walks while striking out eight across four innings.
EDGE Analysis
Teng and Sonny Gray were locked in a pitchers duel Sunday, with the former keeping the Cardinals off the board through the first four frames. Things fell apart in the fifth for Teng, who issued three straight walks before yielding an RBI single and being pulled from the inning, but not before being tagged for three more runs. Teng was able to generate 14 whiffs on 77 pitches (41 strikes) and has registered eight strikeouts in back-to-back starts, but his five walks were a season high. The Giants currently have a six-man rotation, but it's unclear whether Teng will get another turn or head back to Triple-A Sacramento.

Teng (2-3) earned the win over Colorado on Monday, allowing two runs on nine hits and no walks while striking out eight batters over 5.1 innings.
EDGE Analysis
Teng struggled with an 8.78 ERA over four starts in August prior to a brief minor-league demotion, but he looked like a different pitcher Monday. Not only did the right-hander limit the Rockies to two runs, he also fanned eight batters, doubling his previous season-best mark. Teng did allow traffic in all but one of his frames, but the Rockies didn't score on him until after he gave way for a reliever with one out in the sixth. Teng figures to get another turn in the rotation given this strong outing, and he lines up to face the Cardinals in St. Louis this weekend.

The Giants recalled Teng from Triple-A Sacramento on Sunday, and he's expected to start Monday's game against the Rockies in Colorado, Shayna Rubin of the San Francisco Chronicle reports.
EDGE Analysis
The right-hander has struggled to an 8.78 ERA across 13.1 frames in the majors this season, but he'll receive another opportunity with the Giants after starter Carson Whisenhunt (back) was placed on the injured list Sunday. Despite his struggles over four outings with the Giants, Teng has been effective for Sacramento this season with a 3.63 ERA, 1.12 WHIP and 89:22 K:BB across 57 innings.

The Giants optioned Teng to Triple-A Sacramento on Thursday.
EDGE Analysis
Teng has had an excellent season in the minors, but thus far that hasn't translated at the big-league level, as he's posted an 8.78 ERA and 12:9 K:BB over 13.1 frames covering three starts and one relief outing. He'll try to get back on track and earn another opportunity later this season.

Teng (1-3) allowed three runs (two earned) on three hits and a walk while striking out four over 3.1 innings to take the loss versus the Padres on Tuesday.
EDGE Analysis
Teng's last two outings have been against San Diego, and he's allowed a total of 10 runs (eight earned) over five innings against the Giants' division rivals. Teng has maintained the last spot in San Francisco's rotation this month, staying in the majors over Carson Whisenhunt when Landon Roupp returned from an elbow injury. That said, Teng's 8.78 ERA and 12:9 K:BB through 13.1 innings over four appearances haven't inspired much confidence in his major-league readiness. If he gets another start, it's projected to be another challenging matchup this weekend in Milwaukee.

Teng (1-2) took the loss Wednesday against San Diego, allowing seven runs (six earned) on four hits and four walks over 1.2 innings.
EDGE Analysis
After tossing a scoreless first inning, Teng unraveled in the second, allowing six straight batters to reach after recording the first out. It's a disappointing showing from Teng, who held the Nationals scoreless over five innings in his last appearance. With Landen Roupp (elbow) expected to rejoin the Giants' rotation Friday, Teng will likely head back to Triple-A or assume a bullpen role.
