Twins Shake Up Pitching Staff as A.J. Minter Joins Active Roster, Zebby Matthews Optioned

Minnesota's roster makeover continued Saturday. Less than 24 hours after adding another starting pitcher before the trade deadline, the Twins announced another round of transactions ahead of their matchup with the Seattle Mariners. The headline move was expected: newly acquired left-handed reliever A.J. Minter was officially activated. 

To make room on the 26-man roster, the Twins optioned right-hander Zebby Matthews to Triple-A St. Paul. The move isn't necessarily an indictment of Matthews' performance on Friday night. He gave Minnesota five innings, allowed three earned runs, and struck out an impressive 10 hitters against Seattle. However, his overall July results painted a different picture. Across 24 2/3 innings, Matthews posted a 7.66 ERA and 5.69 FIP while recording 23 strikeouts against 14 walks.

With Dean Kremer acquired to bolster the rotation, Matthews became the logical candidate to head back to Triple-A. The timing gives the Twins a fresh bullpen arm in Minter while creating what appears to be a clear opening for Kremer to slide into the starting rotation.

Minnesota also made a change to its 40-man roster, designating right-hander Cody Laweryson for assignment. Laweryson appeared in 15 games for the Twins this season, logging 16 2/3 innings with a 4.86 ERA and 5.08 FIP while striking out 18 and walking eight. Although he flashed intriguing stuff at times, injuries have impacted him this season. A right forearm strain sidelined Laweryson for much of April and May, and after he was optioned to Triple-A in early July, Laweryson has been on the St. Paul injured list since July 19.

His departure immediately created room for another pitcher. Right-hander Garrett Acton was reinstated from the 60-day injured list and optioned to Triple-A St. Paul. Minnesota acquired Acton from the Miami Marlins this spring in exchange for Logan Whitaker, but he has been limited to four appearances after suffering a right shoulder strain that landed him on the injured list at the end of April.

Acton's rehab assignment offered plenty of encouragement. In six innings for St. Paul, he surrendered just one earned run while striking out eight and walking only one. Opponents managed just a .053 batting average against him during that stretch. If the shoulder continues to respond well, Acton could quickly emerge as another bullpen option for a Twins club that has spent the past week aggressively reshaping its pitching staff.

With Minter now in the bullpen, Kremer expected to join the rotation, and additional depth returning from injury, Minnesota's pitching staff looks noticeably different than it did just a few days ago, and the Twins might not be done adding before Monday’s deadline.
