Matzek signed a minor league deal with the White Sox on Friday, Matt Eddy of Baseball America reports. The former Rockie struggled as a starter with the Rockies in 2014 and 2015 before spending the 2016 campaign in the minors working as a reliever. The former highly touted lefty continued to struggle in the minors, however, as he worked a 6.75 ERA across 33 appearances last season. He figures to latch on with one of the White Sox's minor league affiliates at the end of spring training.
Matzek was promoted to Double-A Hartford on Friday, Patrick Saunders of the Denver Post reports. Matzek missed time earlier in the season due to some performance anxiety, but it seems that he's doing well enough to advance to the next stage of the minor leagues. The left-hander's 4.71 ERA wasn't very impressive during his time with High-A Modesto, especially for a reliever, so he'll have to figure some things out if he wants to get back up to the Triple-A level before the conclusion of the season.
Matzek was outrighted to High-A Modesto on Tuesday. Matzek missed the start of the 2016 season as he battled an anxiety issue and was optioned to High-A Modesto immediately following his reinstatement on May 19. The Rockies are now choosing to outright the left-hander, meaning he'll stay with High-A Modesto, but be removed from the 40-man roster. This allows the Rockies to make an addition to their roster, which they would be presumably inclined to do in the coming days.
Matzek (personal) was reinstated from the 15-day DL on Thursday and optioned to High-A Modesto. The left-hander started the season on the disabled list due to an anxiety issue, but he has been gradually progressing throughout the spring. He's off the disabled list as of Thursday, but he will continue to work at High-A Modesto for the time being as he ramps up his workload.
Matzek (personal) walked the only batter he faced in an appearance with High-A Modesto on Wednesday. Matzek was a bit wild, with four of his five pitches being balls, but it's noteworthy that the Rockies felt confident enough in Matzek to put him back in a game situation. He'll continue to get eased back into action over the coming weeks, and the left-hander should hopefully be able to enter the Triple-A rotation once he has stretched out his arm enough.
