Likely to get another start Giants manager Bob Melvin said after Saturday's defeat to the Mets that Teng is expected to get another start, Justice delos Santos of The San Jose Mercury News reports. Teng (0-1)...

Impact Teng's first MLB start -- and 2025 big-league debut -- didn't go well, as the right-hander was tagged for five runs. However, three of those runs came in the first inning, and Teng managed to somewhat settle down thereafter -- the other two runs on his ledger crossed the plate after his departure in the fourth. Teng also managed nine whiffs among his 67 pitches and struck out four batters, and the Giants appear content enough with the right-hander's performance to give him another look as a starter. However, Landen Roupp (elbow) could be activated off the IL soon after Teng's next turn in the rotation, at which point the latter could head back to the minors.

Making first MLB start Saturday Giants manager Bob Melvin said that Teng will start Saturday's game against the Mets at Citi Field, Susan Slusser of the San Francisco Chronicle reports.

Impact Teng made four appearances out of the San Francisco bullpen in the opening month of the 2024 season, but he had pitched exclusively in the minors ever since then before the Giants called him up from Triple-A Sacramento on Friday. The right-hander had been limited to 1.2 innings in his most recent outing with Sacramento on July 25, but that was largely because the Giants wanted to keep him fresh for a potential start with the big club last week that ended up falling to Carson Whisenhunt. The Giants still had another opening in the rotation with Landen Roupp (elbow) recently landing on the injured list, so Teng will be needed for at least one start. Over 25 appearances (four starts) with Sacramento on the season, the 26-year-old righty owns a 3.67 ERA, 1.11 WHIP and 86:21 K:BB in 54 innings.

Headed to majors The Giants selected Teng's contract from Triple-A Sacramento on Friday.

Impact Teng has appeared in 25 games in Triple-A this season and has a 3.67 ERA, 1.11 WHIP and 86:21 K:BB across 54 innings. He's mostly operated out of the bullpen, but he has started in four of his last five outings, most recently July 13 against Salt Lake, when he earned the win after allowing two hits and three walks while striking out seven across five scoreless innings. With Landon Roupp (elbow) on the 15-day IL, Teng could be inserted into the Giants' rotation and start as early as this weekend against the Mets.

Sent to minors camp The Giants reassigned Teng to minor-league camp Wednesday, Justice delos Santos of The San Jose Mercury News reports.

Impact Teng reached the big leagues for the first time in 2024 and made four ineffective relief appearances for the Giants before being non-tendered in November. The Giants re-signed him to a minor-league deal during the offseason, but since Teng is no longer a member of the 40-man roster, he'll likely face an uphill battle to resurface in the big leagues. Teng is expected to open the 2025 season at Triple-A Sacramento.

Re-signs with San Francisco The Giants re-signed Teng to a minor-league contract Nov. 29.

Impact After being non-tendered last month, the right-hander has returned to the organization on a minor-league pact. Teng, 26, spent most of the 2024 season at Triple-A Sacramento, where he put up an 8.60 ERA and 1.81 WHIP over 75.1 innings.

DECEMBER 9, 2024 • ROTOWIRE

No contract from San Francisco The Giants non-tendered Teng on Friday, Justice delos Santos of The San Jose Mercury News reports.

Impact Teng was designated for assignment by the Giants on Tuesday, and the 25-year-old will now enter free agency after being non-tendered Friday. Teng spent most of the 2024 campaign with Triple-A Sacramento, where he struggled with an 8.60 ERA and 1.81 WHIP over 75.1 innings. He did manage to make his major-league debut in late March, and across four outings he gave up 12 earned runs over 11 innings.

NOVEMBER 23, 2024 • ROTOWIRE

Dropped from 40-man roster Teng was designated for assignment by San Francisco on Tuesday.

Impact Teng spent the majority of the 2024 campaign with Triple-A Sacramento, producing an inflated 8.60 ERA and 1.81 WHIP with 61 strikeouts over 75.1 innings in 23 appearances, including 13 starts. Additionally, the right-hander gave up 12 earned runs over 11 innings in four appearances with the Giants last year. He'll now be placed on waivers and if he goes unclaimed, he'll likely remain with Triple-A Sacramento ahead of the 2025 season.

Impact Teng had been on the shelf for three weeks before he made his return to Sacramento. The 25-year-old righty made four appearances out of the San Francisco bullpen earlier this season but is likely to serve as a swingman for Sacramento for the foreseeable future. He holds an 8.66 ERA and 1.76 WHIP over 44.2 innings for the Triple-A club in 2024.

Impact Given that Teng has been on the IL for just a couple of weeks, he shouldn't require an extensive buildup in the lower levels of the minors before he rejoins Sacramento. The 25-year-old righty has a spot on the Giants' 40-man roster but hasn't distinguished himself enough at the Triple-A level this season to earn a call-up. Over his 12 appearances (five starts) for Sacramento before landing on the shelf, Teng turned in a 9.47 ERA and 1.89 WHIP across 38 innings.

JULY 20, 2024 • ROTOWIRE

Headed down to Triple-A Teng was optioned to Triple-A Sacramento on Saturday, Alex Pavlovic of NBC Sports Bay Area reports.

Impact The move corresponds with the Giants removing Sean Hjelle (elbow) from the 15-day IL. Teng has struggled in his first season in the majors, allowing 12 earned runs on 15 hits and eight walks over 11 innings. The right-hander will look to get his command back with Triple-A Sacramento, where he posted a 4.22 ERA and 1.44 WHIP over 79 innings in 2023.

APRIL 20, 2024 • ROTOWIRE

Recalled from Sacramento The Giants recalled Teng from Triple-A Sacramento on Friday, Maria I. Guardado of MLB.com reports.

Impact The move corresponds with Luke Jackson (back) being placed on the Giants' injured list. Teng started 2023 in Double-A Richmond but managed to work his way up to Triple-A Sacramento in June. With Sacramento, Teng posted a 4.22 ERA, 1.44 WHIP and 96:48 K:BB over 79 innings while going 6-5 over 16 starts.

MARCH 29, 2024 • ROTOWIRE

Receives 40-man spot The Giants added Teng to their 40-man roster Tuesday.

Impact Teng split time between Double-A Richmond and Triple-A Sacramento last season, putting up a 4.42 ERA and 1.36 WHIP through 126.1 combined innings. Teng needs to work on his command before he can be relied on in the majors. but his impressive strikeout numbers warrant protection from the upcoming Rule 5 Draft.

NOVEMBER 14, 2023 • ROTOWIRE

Promoted to Triple-A Teng was promoted from Double-A Richmond to Triple-A Sacramento on Saturday.

Impact Teng has shown some upside with a 13.0 K/9 over 47.1 innings with Richmond this season. He also posted a 4.75 ERA in his second season at Double-A, but his 3.23 FIP suggests he had some poor luck. He rides a sweeper and mixes in a fastball, though he may need to develop a third pitch to navigate the hitter-friendly Pacific Coast League. He'll likely spend the rest of 2023 at Triple-A.

JUNE 18, 2023 • ROTOWIRE

Sweeper leading to success Teng has a 2.63 ERA, 0.96 WHIP and 36 strikeouts in 24 innings across six starts for Double-A Richmond.

Impact According to Dylan White of Baseball America, Teng throws his sweeper nearly two-thirds of the time. That's an extreme percentage, especially for a starting pitcher, but his breaking ball is a better pitch than his 94-mph fastball. Essentially a two-pitch pitcher right now, Teng has gone between 3.2 innings and 4.2 innings in all six starts.
