[By Kang Tae-gu | Sports Today] The expected major-league call-up for Go Woo-seok (Detroit Tigers) was nixed on Friday.<\/p>\n

MLB.com reported on May 29 (KST) that the Tigers placed veteran closer Kenley Jansen on the 15-day injured list with inflammation in his pelvis.<\/p>\n

Rather than promoting Go, Detroit selected left-hander Drew Somers to fill Jansen\u2019s spot.<\/p>\n

Somers had been the 27th-man call-up for the May 25 game against the Baltimore Orioles, was optioned back to the minors, then returned immediately under the injured-player replacement rule.<\/p>\n

The decision came down to 40-man roster logistics.<\/p>\n

Somers is already on Detroit\u2019s 40-man roster, making it straightforward to add him to the active 26-man roster. Go is not on the 40-man, and the Tigers were not able to clear a 40-man spot to promote him.<\/p>\n

This season, Go has appeared in 16 minor-league games, going 2-1 with a 1.38 ERA.<\/p>\n

He fractured the index finger on his right hand during spring camp, rehabbed and then raised expectations by pitching well for South Korea in the March World Baseball Classic (WBC).<\/p>\n

After the WBC, however, Go struggled in Triple-A \u2014 two outings produced a 20.25 ERA and a loss, and he was demoted to Double-A.<\/p>\n

His former KBO club, the LG Twins, explored bringing him back after closer Yoo Young-chan\u2019s injury, but Go declined the offer.<\/p>\n

That choice drew criticism, yet Go remained confident. He responded with a dominant stretch in Double-A, posting a 0.66 ERA over eight appearances and earning a promotion back to Triple-A on May 9.<\/p>\n

He continued to pitch well at Triple-A and pushed for a big-league call, but this time the majors stayed out of reach.<\/p>\n
