Keller did not make the Angels' 30-man roster.

EDGE Analysis

The Angels acquired Keller from the Marlins in January. He gave up four earned runs in five innings between spring and summer contests, contributing to his exclusion from the active roster. Keller will head to the Angels' alternate training site for the start of the campaign.

Keller was optioned to Triple-A Salt Lake on Sunday.

EDGE Analysis

The Angels traded for Keller in early January and gave him a four-game audition in spring training. Though the right-hander struck out five batters over four innings in Cactus League play, he also allowed five hits and four earned runs. Keller has consistently posted strong strikeout numbers in the minors, but his ERA was a less-than-impressive 4.50 at the Triple-A level last season.

Keller was traded from the Marlins to the Angels on Monday in exchange for minor-league catcher Jose Estrada.

EDGE Analysis

The 26-year-old debuted in 2019 with a solid 3.38 ERA in 10.2 innings, but his underlying metrics weren't promising. It took an .091 BABIP to get him to that mark, and he walked batters at a 17.4 percent clip. The righty also recorded a mediocre 4.50 ERA in 54 innings of relief for Triple-A New Orleans.

Keller was designated for assignment by the Marlins on Friday, Jordan McPherson of the Miami Herald reports.

EDGE Analysis

The move clears a spot for Yimi Garcia, signed in a corresponding move. Keller made his MLB debut last season, posting a 3.38 ERA in 10.2 innings of relief.

The Marlins recalled Keller from Triple-A New Orleans ahead of Sunday's game against the Pirates.

EDGE Analysis

Keller will provide Miami with a fresh arm out of the bullpen after the team needed four relievers to cover the final 5.1 innings of Saturday's 9-3 loss to the Phillies. Right-hander Tyler Kinley was optioned to Triple-A in a corresponding move.

Keller was optioned to Triple-A New Orleans on Monday.

EDGE Analysis

Keller spent just four days on the big-league roster, allowing a run in 1.2 innings in his only appearances. He'll make way on the roster for Ryne Stanek (hip), who returns from the injured list in a corresponding move.

The Marlins recalled Keller from Triple-A New Orleans ahead of Thursday's game against the Twins, Jordan McPherson of the Miami Herald reports.

EDGE Analysis

The righty reliever will fill the opening on the 25-man roster created Wednesday by the trade that sent Zac Gallen to the Diamondbacks. An 18th-round pick in 2015, Keller earned his first call to the big leagues after racking up 64 strikeouts and nine saves in 48.1 innings for New Orleans. Like many Triple-A pitchers this season, however, Keller struggled to rein in the long ball, surrendering eight home runs.
