Giants recall pitcher with intriguing strikeout potential

The Giants announced a series of roster moves Friday, with outfielder Luis Matos and right-hander Kai-Wai Teng recalled from Triple-A Sacramento. Teng will be making his major league debut as soon as he gets into a game. In corresponding moves, outfielder Mike Yastrzemski has been placed on the paternity list while right-hander Luke Jackson goes on the 15-day injured list with a lower back strain. Daniel Alvarez-Montes of El Extrabase had reported earlier that Matos would be taking Yastrzemski’s place on the roster. Susan Slusser of the San Francisco Chronicle first relayed that Teng was at the ballpark Friday.

Jackson departed Thursday night’s game with an apparent back issue. He didn’t seem terribly concerned with the severity but the club evidently feels he will need at least a couple of weeks to get back on the mound.

His injury will pave the way for Teng to be called up to the big leagues for the first time. The 25-year-old was signed by the Twins as an international amateur out of Taiwan. He came to the Giants in the 2019 deadline deal that sent Sam Dyson to Minnesota.

He has climbed the rungs of the minor league ladder since then, showcasing strikeout stuff but also control issues. He split last year between Double-A and Triple-A, making 28 starts and one relief appearance, tossing 126 1/3 innings. He struck out 29.8% of batters faced but also gave out free passes at a 12.4% clip, leading to a combined earned run average of 4.42.

He was added to the club’s 40-man roster in November to keep him out of the Rule 5 draft. He didn’t make the Opening Day roster but Jackson’s injury will allow him to come up just after. He’ll likely be in a long relief role out of the bullpen. The club is currently operating with 14 positions players and just 12 pitchers, meaning that eating multiple innings from the bullpen will be valuable for the club.
