Vargas signed a minor-league contract with the Diamondbacks on Friday, Jon Heyman of the New York Post reports.

Vargas spent most of his time at Triple-A Reno this past season but still managed to appear in 38 games for the D-backs, during which he slashed .270/.292/.383 with 19 RBI and 12 runs scored. He'll officially return to the organization to begin the 2026 campaign, although he's expected to remain an organizational depth piece.

The Mets outrighted Waddell to Triple-A Syracuse on Friday, Anthony DiComo of MLB.com reports.

New York designated Waddell for assignment earlier this week, and he'll remain in the organization after clearing waivers. Waddell posted a 3.45 ERA, 1.28 WHIP and 22:11 K:BB across 31.1 major-league innings last season.

Arizona outrighted Jarvis to Triple-A Reno on Friday, Alex Weiner of ArizonaSports.com reports.

Jarvis was booted from the 40-man roster and designated for assignment last Friday but cleared waivers and will remain with the Diamondbacks' organization. The 27-year-old right-hander appeared in 12 games at the big-league level with Arizona last season and carded a 5.73 ERA, 1.50 WHIP and 21:10 K:BB across 22 innings.

The Rays claimed Bido off waivers from Atlanta on Friday.

Bido has now bounced around via waivers from the Athletics to Atlanta and now to Tampa Bay this month. The right-hander had an unsightly 5.87 ERA and 18.7 percent strikeout rate in 2025, but he was much better in 2024 with a 3.41 ERA and 24.3 percent strikeout rate. Bido does not have minor-league options left, but he offers the flexibility to be used either in a starting or relief role.

Atlanta outrighted Molina to Triple-A Gwinnett on Friday.

Molina was claimed off waivers from the Rockies earlier this month. The 23-year-old right-hander sports an ugly 6.96 ERA, 1.61 WHIP and 65:28 K:BB across 94.1 innings spanning 52 appearances (two starts) over the previous two seasons with Colorado.

The Orioles designated Walker for assignment Friday, Roch Kubatko of MASNSports.com reports.

Walker was claimed off waivers from Atlanta earlier this month after he was previously DFA'd by Baltimore in November. He's now going to be exposed to waivers once again. The 31-year-old left-hander appeared in three games for Toronto last season, turning in a 7.20 ERA, 2.00 WHIP and 8:2 K:BB across five innings of work at the big-league level.

The Pirates acquired Montgomery from the Rays on Friday in a three-team trade, Chandler Rome and Ken Rosenthal of The Athletic report.

Montgomery logged a 5.67 ERA and walked 27 over 46 innings with the Rays in 2025, but he also struck out 63 batters and, at 98.7 mph, has one of the hardest average four-seamer velocities in the game. The lefty has past starting experience, but the Pirates are likely to keep Montgomery in the bullpen, and he could work his way into high-leverage appearances.

The Rays acquired Brito and Jacob Melton from the Astros on Friday in a three-team trade that sent Mike Burrows to the Astros and Brandon Lowe, Jake Mangum and Mason Montgomery to the Pirates, Chandler Rome and Ken Rosenthal of The Athletic report.

The 21-year-old right-hander spent the entire 2025 campaign at High-A Asheville and started all 12 games in which he appeared, registering a 3.28 ERA and 11.9 K/9 across 49.1 innings. Brito missed some time with an unspecified injury but was back to full strength in October.

The Pirates acquired Mangum from the Rays on Friday in a three-team trade, Chandler Rome and Ken Rosenthal of The Athletic report.

Mangum had a successful rookie season in 2025 with the Rays, slashing .296/.330/.368 with three home runs and 27 stolen bases. He'll turn 30 in March but is under team control through 2030. Mangum could be the favorite to open the 2026 season as the Pirates' starting left fielder, and he's capable of handling all three outfield spots.

The Rays acquired Melton and Anderson Brito from the Astros on Friday in a three-team trade that sent Mike Burrows to the Astros and Brandon Lowe, Jake Mangum and Mason Montgomery to the Pirates, Chandler Rome and Ken Rosenthal of The Athletic report.

Melton was one of Houston's top prospects, and the 25-year-old got his first taste of MLB action last season, appearing in 32 games for the Astros. The outfielder slashed .157/.234/.186 with one triple, seven RBI, seven runs scored, seven stolen bases and a 6:29 BB:K across 78 big-league plate appearances. He figures to initially slot into Tampa Bay's outfield mix behind Chandler Simpson, Cedric Mullins, Josh Lowe and potentially even Jake Fraley.
