Casilla inked a minor-league contract with Colorado on Thursday, Robert Murray of The Athletic reports.

EDGE Analysis

Casilla was recently released by the Athletics after making 26 appearances with the club in 2018. During those outings, he logged a 3.16 ERA and 1.21 WHIP while accumulating a subpar 22:20 K:BB across 31.1 innings of relief. The 37-year-old will provide extra depth within the Rockies' system at the Triple-A level.

Casilla was released by Oakland on Thursday, Julian McWilliams of The Athletic Bay Area reports.

EDGE Analysis

Casilla was designated for assignment Saturday, and he'll look to latch on elsewhere after being officially released. The 37-year-old right-hander had served as a reliever for the Athletics over the past two seasons.

Casilla was designated for assignment Saturday.

EDGE Analysis

On the surface, the move is something of a surprise, as Casilla had a solid 3.16 ERA in 31.1 innings so far this season. His underlying numbers were poor, however, with a 16.7 percent strikeout rate and a 15.2 percent walk rate, so his low ERA seems primarily attributable to a .209 BABIP. Joey Wendelken's contract was selected in a corresponding move.

Casilla, who fired a scoreless inning in which he recorded two strikeouts in an extra-innings win over the Angels on Sunday, has logged 3.2 scoreless frames across three outings since returning from the disabled list with a shoulder injury.

EDGE Analysis

Casilla has yet to issue a walk through that trio of appearances as well, always an encouraging sign for a pitcher with as many control issues as he typically exhibits. The 37-year-old has made significant improvements in both his ERA (2.84) and WHIP (1.07) over last season's respective 4.27 and 1.36 figures, but his fantasy utility remains limited in many formats due to his lack of hold and save opportunities.

Casilla (shoulder) was activated from the disabled list prior to Friday's game.

EDGE Analysis

Casilla didn't wind up missing too much time on the DL after going down with a shoulder strain near the end of May, though this has been a consistent issue for the right-hander since spring training, so it's worth keeping an eye on moving forward. Over 16 appearances this year, Casilla has logged a 3.32 ERA and 1.15 WHIP with a 14:14 K:BB over 21.1 innings of relief.

Casilla (shoulder) could be activated from the disabled list as soon as Friday according to manager Bob Melvin, Jane Lee of MLB.com reports.

EDGE Analysis

The 37-year-old has made one rehab start, firing a scoreless first inning for High-A Stockton on Tuesday. That appears to have been enough to corroborate Casilla's return to health, and with the Athletics' bullpen still short-handed, his presence after a relatively brief absence would be a welcome sight.

Casilla (shoulder) will begin a minor-league rehab assignment with High-A Stockton on Tuesday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Casilla has been sidelined since May 26, but it sounds like he's already nearing a return to action. The A's will reevaluate him after Tuesday's appearance with the Ports, and if everything checks out OK, the veteran reliever could be back with the big club sometime this week.

Casilla (shoulder) was placed on the 10-day disabled list Saturday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

As expected, Casilla was sent to the shelf with a shoulder strain that has been bothering him since spring training. It's unclear how long the issue will keep him sidelined, but manager Bob Melvin is apparently hopeful that the veteran will only be forced to miss the 10-day minimum, per Slusser. Chris Bassitt was recalled from Triple-A Nashville in a corresponding roster move.

Casilla allowed a hit and two walks in a scoreless ninth inning during a loss to the Mariners on Wednesday.

EDGE Analysis

The 37-year-old reliever had faltered to an extent each of his last two times on the mound, yielding a combined four earned runs over the four innings encompassing those outings. While the scoreless effort was certainly a welcome sight, Casilla's career-long control issues persist, and he's now issued multiple walks in five consecutive appearances. However, his ability to work multiple innings as needed and his extensive experience figure to continue affording him a heavy workload.

Casilla allowed an earned run on two hits and two walks across two innings in a loss to the Yankees on Sunday. He also recorded two strikeouts.

EDGE Analysis

The outing included some of Casilla's strengths and weaknesses, as he struggled with his control but got himself out of trouble by missing bats as well. The 37-year-old reliever saw a four-appearance scoreless streak snapped, and he's now issued multiple free passes in three straight outings.
