Tseng is dealing with a shoulder injury and has yet to face hitters since signing a minor-league deal with the Rangers in early April, Evan Grant of The Dallas Morning News reports.

EDGE Analysis

The Rangers have a need for rotation depth at both the major-league and Triple-A levels, but it doesn't appear Tseng will be a potential solution to those problems anytime soon. Based on where he's currently at in his recovery from injury, it's unlikely that he'll report to one of the Rangers' minor-league affiliates until July at the earliest.

Tseng signed a minor-league contract with the Rangers on Wednesday.

EDGE Analysis

Tseng is headed south after being released by the Cubs last week. The 24-year-old spent most of the 2018 campaign with Triple-A Iowa, compiling a 6.27 ERA and 1.49 WHIP in 136.1 innings (26 starts). Tseng will report to extended spring training to begin a throwing program.

Tseng was released by the Cubs on Thursday, Patrick Mooney of The Athletic reports.

EDGE Analysis

Tseng appeared in one game for the Cubs this season, giving up three runs on four hits in two innings pitched. The 24-year-old was designated for assignment Saturday before ultimately being released Thursday. Tseng has a career 9.00 ERA through eight innings pitched in the majors.

Tseng was designated for assignment Saturday.

EDGE Analysis

Tseng has yet to appear in a game this season after making spot starts in each of the past two seasons for the Cubs. He'll head to Triple-A Iowa and make regular starts there until an opportunity presents itself in the majors.

The Cubs optioned Tseng to Triple-A Iowa on Saturday, Gordon Wittenmyer of the Chicago Sun-Times reports.

EDGE Analysis

Tseng made a spot start with the Cubs in both of the past two seasons, but the right-hander wasn't under consideration for an Opening Day rotation spot with Yu Darvish reporting to camp healthy. The 24-year-old will instead make regular starts at Iowa to begin the upcoming campaign and wait for injuries at the big-league level to open up an opportunity.

Tseng will start the Cubs' Cactus League opener against the Brewers on Saturday, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

Tseng had a rough year in 2018, finding little success in the minors (6.27 ERA in 26 starts) nor the majors (three earned runs in two innings pitched). He'll get the first starting nod of spring training, though the Cubs' rotation is chock full of veteran arms, likely leaving Tseng with a ticket back to Triple-A for much of 2019.

Tseng was optioned to Triple-A Iowa on Wednesday, Bruce Miles of the Chicago Daily Herald reports.

EDGE Analysis

The soft-tossing righty gave up three earned runs on four hits (one home run) in two innings in his spot start Tuesday, so it is no surprise to see him headed back to the Iowa Cubs. He may be summoned for another spot start or two this season, or perhaps to serve as a long reliever, but is unlikely to gain relevancy in most fantasy formats.

Tseng pitched just two innings in Tuesday's start, allowing three runs on four hits while striking out three against the Marlins.

EDGE Analysis

Tseng was called up to make a spot start in place of Yu Darvish (illness), and was only given two frames despite sitting at a pitch count of just 39. There was no indication of any injury, but he didn't look sharp and yielded three runs in the first, leading to manager Joe Maddon's quick hook. Darvish would be eligible to return for Monday's tilt against the Braves, so it remains unclear if Tseng will make his next start with the big league club.

Tseng was called up from Triple-A Iowa and will start Tuesday against the Marlins, Bruce Levine of 670TheScore.com reports.

EDGE Analysis

Tseng pitched six innings for the Cubs last season, allowing five runs. He has a 8.04 ERA in 31.1 innings for Iowa so far this season, though he had a much better 1.80 ERA in nine starts at the same level in 2017. He projects as a back-end starter at best with no noteworthy pitches.

Tseng was scratched from his start with Triple-A Iowa on Monday, Bruce Miles of the Chicago Daily Herald reports.

EDGE Analysis

Though this may normally signal an injury, it seems more likely that it is in response to Yu Darvish (illness) landing on the disabled list Monday. Tseng may be called up to the big leagues to fill the vacancy in the Cubs' rotation, though the official move likely won't be announced until Tuesday before the game. If he does in fact fill in for Darvish, he'll take on the Marlins at Wrigley Field.
