Matzek has allowed only one hit and posted a 0.00 ERA and 7:0 K:BB through 3.2 innings of relief this spring.

EDGE Analysis

The southpaw was the 11th overall pick in the 2009 draft, but after climbing steadily through the Rockies' system he developed anxiety issues in the majors and couldn't find the plate, eventually washing out of organized baseball in 2016. Per David O'Brien of The Athletic, Matzek has since learned to put himself in a better mental space and rebuilt his mechanics in independent ball, and he was rewarded with a minor-league deal by Atlanta last year. The 29-year-old isn't on the 40-man roster and is still a long shot to break camp in the Braves' bullpen, but even resuming his pro career is a major accomplishment, and he could be on the cusp of returning to The Show.

Matzek signed a minor-league contract with Arizona on Tuesday, Robert Murray of The Athletic reports.

EDGE Analysis

Matzek has made 24 starts and one relief appearance in the big leagues, though none have come since 2015. The southpaw has been out of affiliated baseball since 2016. Last season with the Texas AirHogs of the independent American Association, he threw 88.2 innings with an unimpressive 5.89 ERA.

The Mariners released Matzek from the minors Saturday, Chris Cotillo of SB Nation reports.

EDGE Analysis

Matzek signed a minor-league contract with the Mariners in February. The 2009 first-round pick last pitched in the majors for the Rockies in 2015, and did not pitch in the minors after being released by the White Sox last spring.

Matzek signed a minor league deal with the White Sox on Friday, Matt Eddy of Baseball America reports.

EDGE Analysis

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.

EDGE Analysis

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.

EDGE Analysis

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.

EDGE Analysis

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.

EDGE Analysis

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.

Matzek (personal) will pitch in an extended spring training game Saturday, Nick Groke of the Denver Post reports.

EDGE Analysis

Matzek seems to be getting near a return to regular game action now that he's able to pitch in game situations again. As long as no setbacks occur, the left-hander could enter the Triple-A rotation within the next week or two.

Matzek (personal) will throw batting practice for the first time in extended spring training Friday, CBS Denver reports.

EDGE Analysis

It's good to see Matzek making progress in his return from performance anxiety issues, but he still has a ways to go before returning to game action. If he can get through a few batting practice sessions, the next steps would be to throw in simulated games and rehab assignments before returning to the mound full-time. His timetable for return should become clearer once he makes the next step in his rehab process.
