MLB Player News

The Red Sox designated Kelly (elbow) for assignment on Monday, Chris Cotillo of MassLive.com reports.

Kelly spent most of the second half of the regular season on the 60-day injured list for the Red Sox. He appeared in 17 games out of Boston's bullpen prior to the injury, recording a 3.31 ERA, 1.29 WHIP and 14:7 K:BB across 16.1 innings.

The Tigers signed Waguespack to a one-year, $1.3 million contract Monday.

Detroit acquired Waguespack from the Brewers in June, and the right-hander settled in as a key bullpen piece for the Tigers over the second half of the season. He produced a 2.49 ERA, 0.92 WHIP and 35:18 K:BB across 47 innings.

The Tigers exercised Anderson's $10 million club option for the 2027 season Monday.

Anderson returned to the MLB last winter after spending the previous four years overseas. In his first season with the Tigers, Anderson logged a 3.67 ERA, 1.27 WHIP and 114:43 K:BB across 108 innings. He made 11 starts, including nine following the trade deadline departure of Tarik Skubal in August. He might get a chance to earn a spot in the rotation during the spring.

Zulueta cleared waivers and was outrighted to Triple-A Norfolk on Monday.

Zulueta was claimed off waivers from the Cubs over the summer and spent all of last season in Triple-A, where he compiled a 3.74 ERA, 1.39 WHIP and 24:9 K:BB across 21.2 innings of relief in the Baltimore organization.

The Orioles claimed Abner off waivers from the Mets on Monday.

Abner split the 2026 season with the Diamondbacks, Giants and Mets and will now head to Baltimore after appearing in 13 games out of the bullpen with Arizona and San Francisco. He was hammered for a combined 17 runs (15 earned) on 21 hits and 11 walks with 10 strikeouts across 19 innings. Abner will look for a fresh start with Baltimore in the spring.

The Orioles claimed White off waivers from the Marlins on Monday.

White made his major-league debut with Miami this past season but was tagged for five runs on one hit, four walks and a hit-by-pitch across two-thirds of an inning. He spent the bulk of the campaign with Triple-A Jacksonville, logging a 2.41 ERA, 1.21 WHIP and 62:31 K:BB across 56 frames. The 25-year-old will likely get a shot to break camp with Baltimore.

The Astros selected Munoz's contract from Triple-A Sugar Land on Monday.

Munoz was dropped from the Astros' 40-man roster shortly after Opening Day after he was knocked around for seven runs in four innings. However, he's earned his way back onto the roster after posting a 3.06 ERA and 76:21 K:BB over 53 innings at Sugar Land.

The Mariners claimed Mattson off waivers from the Pirates on Monday, Colin Beazley of the Pittsburgh Post-Gazette reports.

Mattson posted a 2.45 ERA and 45:19 K:BB over 47.2 innings in 2025, but he stumbled in 2026 with a 5.35 ERA and 36:18 K:BB over 38.2 frames. The 31-year-old will look to fill a middle relief role in Seattle.

Blue Jays general manager Ross Atkins said last week of Tiedemann that the team is "thinking of him as a reliever" heading into the 2027 season, Shi Davidi of Sportsnet.ca reports.

Tiedemann returned from a nearly two-year absence in 2026 due to Tommy John surgery and multiple setbacks, allowing one run with an 8:6 K:BB over six innings during his brief time in the big leagues. The 24-year-old boasts a 39.1 percent strikeout rate in the minors, but he's logged a total of just 152 innings since being drafted in 2021 because of myriad injuries.

The Red Sox exercised Whitlock's (leg) $8.25 million club option for 2027 on Sunday, Ari Alexander of 7 News Boston reports.

The right-hander pitched through a fractured right tibia down the stretch, but he still pitched well as he didn't give up an earned run in his final nine outings of the regular season. It's no surprise that Boston picked up the option after he posted a 1.72 ERA, 0.90 WHIP and 59:9 K:BB while recording four saves and 27 holds in 54 regular-season appearances.
