Curtis was released from Triple-A Nashville, T.R. Sullivan of MLB.com reports.

EDGE Analysis

Curtis, who pitched in eight games for the Rangers in 2018, leaves the organization after posting an 8.90 ERA over 30.1 innings at Nashville. The 27-year-old left-hander becomes a free agent.

Curtis returned to the Rangers on a minor-league deal on Monday.

EDGE Analysis

The deal includes an invitation to major-league spring training. The lefty has thrown 38 major-league innings over the last three seasons, pitching for four different organizations. He owns a 4.74 ERA and an ugly 34:35 K:BB.

Curtis was non-tendered by Texas on Friday.

EDGE Analysis

Curtis spent time at the big-league level with both the Phillies and Rangers in 2018. He registered a 4.96 ERA with 18 punchouts over 16.1 innings and struggled with his command, issuing 19 walks over that span.

Curtis was recalled from Triple-A Round Rock on Saturday, T.R. Sullivan of MLB.com reports.

EDGE Analysis

Curtis will join the Rangers for the first time since being claimed in early August. The 26-year-old has a career 3.73 ERA and 1.63 WHIP over 31.1 innings and adds to the Rangers' bullpen depth with September's expanded rosters.

Curtis was claimed off waivers by the Rangers on Tuesday and optioned to Triple-A Round Rock.

EDGE Analysis

Curtis has a solid 3.73 career ERA in 31.1 major-league innings, but his walk and strikeout rates each sit at an ugly 17.7 percent. He could be called up when the Rangers need another lefty or a new long man in the bullpen. Brandon Mann was designated for assignment in a corresponding move.

Curtis was designated for assignment by the Phillies on Tuesday.

EDGE Analysis

Curtis has an excellent 1.86 ERA in 9.2 innings for the Phillies this season, though his underlying numbers don't support that success, as he's walked as many batters as he's struck out (10). The move makes room on the 40-man roster for deadline-day acquisition Wilson Ramos.

Curtis was optioned to Triple-A Lehigh Valley on Sunday.

EDGE Analysis

Curtis struck out three batters across 1.1 innings in Friday's matchup, but the Phillies needed a refresher in the bullpen after multiple days of heavy use. With Vince Velasquez (forearm) headed to the DL, the team called up Jake Thompson and activated Pat Neshek (forearm) in corresponding moves.

Curtis threw a pair of scoreless innings in Tuesday's loss to the Yankees, hitting a batter and allowing a hit and a walk while striking out one.

EDGE Analysis

Curtis' 2.16 ERA is the lowest of the three lefties in the Philadelphia bullpen, outpacing Austin Davis (2.70) and Adam Morgan (5.57). That low ERA has come in 8.1 innings, however, and it isn't supported by his underlying numbers. He has more walks (8) than strikeouts (7), with ERA estimators such as SIERA and xFIP putting his deserved ERA north of 6. It would be quite surprising to see him move into a more important role any time soon.

Curtis was recalled from Triple-A Lehigh Valley on Friday.

EDGE Analysis

It's a somewhat surprising call-up, as the Phillies already have a pair of lefties in the bullpen in Adam Morgan and Austin Davis. Morgan hasn't been particularly impressive, though, and Davis has recorded just a single major-league out, so Curtis has a chance to impress and stick around. The 25-year-old has a 4.33 ERA in 27 career big-league innings, with an ugly 21:23 K:BB. Jake Thompson was optioned to Lehigh Valley in a corresponding move.

Curtis was optioned to Triple-A Lehigh Valley on Thursday.

EDGE Analysis

Curtis allowed two earned runs off three hits and three walks while striking out a pair over two innings of relief against the Giants during Wednesday's game, and will now head back to Lehigh Valley in exchange for Jake Thompson. During his brief stay with the Phillies, Curtis wasn't able to find the strike zone, walking a total of seven batters across just 5.1 innings. With the revolving door that is a major-league bullpen, expect to see Curtis back with Philadelphia at some point later on this year.
