Biographical Information[edit]

Jen-Ho Tseng debuted for the Taiwan national team when he was just 18 years old and made the majors five years later. His sister Chi Tseng has pitched for Taiwan's women national team.

Tseng was 0-1 with a 1.80 ERA in the 2011 Asian Junior Championship. In the 2012 World Junior Championship, he was superb at 3-0, 0.84 with a save. In 21 1/3 innings, he fanned 22 and allowed only 12 hits and 2 walks. He beat Canada, South Korea and Colombia. He was second in the event in strikeouts (four behind Shintaro Fujinami), led in wins and tied Jae-min Shim for the most appearances (6). He was named the tourney's All-Star relief pitcher.

Jen-Ho then was the only high schooler picked for Taiwan's squad in the 2013 World Baseball Classic Qualifiers, 3 1/2 years younger than Yao-Lin Wang, the next-youngest). He made his lone appearance in their 9-0 win over New Zealand in the finale. Relieving Kai-Wen Cheng with a 7-0 lead in the 7th, he retired Moko Moanaroa then walked Beau Bishop. Tseng recovered to fan two players with minor league experience in the US, Alan Schoenberger and Tim Auty, to end the inning. He was replaced by Yen-Feng Lin in the 8th. He remained with Taiwan for the 2012 Asian Championship, going 1-0 and tossing six shutout innings; he beat rival South Korea to help ensure Taiwan getting a Silver Medal and Korea the Bronze.

On July 25, 2013, he signed a minor league contact with the Chicago Cubs. He went 6-1, 2.40 for the Kane County Cougars of the Midwest League in his first season in organized baseball in 2014, then followed that in 2015 by going 7-7, 3.55 for the Myrtle Beach Pelicans of the Carolina League. With the Tennessee Smokies of the Southern League in 2016, he was 6-8, 4.29 in 22 starts. He had an excellent season in the minors in 2017, split between Tennesse and the AAA Iowa Cubs as he was a combined 13-4, 2.54 in 24 starts. He tied Duane Underwood for second in the Cubs chain in wins and led with 122 strikeouts (3 ahead of Seth Frankoff). He was a mid-season All-Star in the Southern League and was named the Cubs minor league pitcher of the year for the second time, having already been the recipient of the honor after his first season in 2014. He was called up to Chicago in September. He was the 10th major league pitcher from Taiwan. He was obviously nervous in his debut against the New York Mets on September 14th, as his first pitch was behind the batter, then he fell while covering first base against the next batter, being charged with an error, and also collected a hit batsman before the inning was over. He ended up giving up 5 runs in 3 innings, but the Cubs still won the game, 14-6.

Tseng collected his first career win against the St. Louis Cardinals on September 28. He relieved Justin Wilson in the 8th inning, and he pitched 3 shutout innings with 2 strikeouts. Taylor Davis's double in the 11th inning drove in the winning run. Those were the only two games Tseng pitched in the 2017 season, and he was 2-15 with a 6.27 ERA for the Iowa Cubs in 2018. Tseng pitched one game in The Show in 2018, and he surrendered 3 runs in 2 games versus the Miami Marlins. The Cubs released him, and Tseng signed a minor league contact with the Texas Rangers. He only pitched 2 games combined in the Rangers system, and he became a free agent.

The Kaohsiung native then pitched for the Auckland Tuatara. He was 0-2 with a 13.50 ERA in 3 games in the 2019-2020 Australian Baseball League. Tseng announced that he would join the CPBL, and the Rakuten Monkeys drafted him in the third round of the 2020 CPBL Draft. Tseng was 1-3 with a 3.06 ERA in 2021, then he improved to 7-2 with a 2.48 ERA in 2022. He was named the starter of 2022 Taiwan Series Game 2, and he pitched 5 2/3 innings while allowing 3 runs. Tyler Viza outdueled him as he pitched 8 innings with only one run allowed. Tseng then pitched 2 innings with only an unearned run allowed in Game 4, but the Monkeys were still swept by the CTBC Brothers.

Tseng was on the roster of Taiwan for the 2023 World Baseball Classic, but he withdrew due to a waist injury. He ended up 6-6 with a 4.55 ERA in 2023. In the 2023 Taiwan Series, Tseng started in Game 3, and he allowed 2 runs in 5 innings. When Jake Dahlberg was destroyed early in Game 7, Tseng relieved him and he pitched 7 innings with only one run allowed. The Monkeys still lost the title to the Wei Chuan Dragons. Tseng then pitched for Taiwan in the 2023 Asian Championship. He started against Japan, and he pitched 4 2/3 shutout innings. Taiwan won Silver in the event.

Tseng throws a slider, sinker, changeup and knuckle-curve. His peak speed has been 95 mph as of 2012.
