The Cincinnati Reds acquired reliever Sam Moll in a trade with the Oakland Athletics on Monday.

The addition of Moll puts another left-hander in Cincinnati's bullpen as it tries to become the first team to win a division after losing at least 100 games in the previous season. 

The San Francisco Giants acquired outfielder AJ Pollock and utilityman Mark Mathias from the Seattle Mariners on Monday for a player to be named later, both teams announced.

Pollock is on the injured list with a hamstring strain and prior to that had struggled after signing a one-year, $7 million free agent contract with Seattle in the offseason. 

The Cubs announced Monday they reacquired Washington Nationals third baseman Jeimer Candelario, nearly six years to the day they traded him to the Detroit Tigers.

In return, the Cubs are sending prospects Kevin Made and DJ Herz back to the Nationals.

The New York Mets continued to deal from their disappointing 2023 team, trading outfielder Mark Canha to the Milwaukee Brewers for minor league pitcher Justin Jarvis, the team announced Monday

The 34-year-old Canha was a vital performer during the Mets' 101-win campaign in 2022 and still had the third-highest on-base percentage among New York's regulars this year.

The struggling Diamondbacks acquired closer Paul Sewald from the Seattle Mariners on Monday, hoping to shore up a bullpen that has faltered over the past month and taken Arizona from leading the National League West to out of a playoff spot.

The Los Angeles Angels bolstered their lineup in a trade with the Colorado Rockies on Sunday, acquiring infielder C.J. Cron and outfielder Randal Grichuk along with cash considerations for minor league LHP Mason Albright and RHP Jake Madden.

The Toronto Blue Jays acquired flamethrowing reliever Jordan Hicks from the St. Louis Cardinals on Sunday, reinforcing their bullpen the day after they placed closer Jordan Romano on the injured list.

Hicks, perhaps the most sought-after relief arm on the trade market, was the first of what's expected to be a number of players from a disappointing Cardinals team to move. Soon after the Hicks deal was consummated, St. Louis traded left-handed starter Jordan Montgomery and right-handed reliever Chris Stratton to Texas.

In return for Hicks, the Blue Jays will send a pair of minor league right-handers to St. Louis: 21-year-old Sem Robberse and 22-year-old Adam Kloffenstein, both at Double-A.

The Texas Rangers further fortified themselves for a championship run Sunday, acquiring left-handed starter Jordan Montgomery and right-handed reliever Chris Stratton from the St. Louis Cardinals one day after finalizing a deal for ace Max Scherzer.

With the best offense in baseball, the Rangers tapped into their plentiful minor league system, sending two top prospects -- infielder Thomas Saggese and right-hander Tekoah Roby -- along with left-handed reliever John King to St. Louis.

The Rangers acquired right-hander Max Scherzer from the Mets in a Saturday trade, fortifying the Rangers' rotation for a World Series run as the dismantling of the disappointing Mets continues, sources familiar with the situation told ESPN, confirming multiple reports.

While a tentative deal was struck earlier in the day, it was contingent on Scherzer waiving a no-trade clause. One day after expressing frustration over the Mets' trade of closer David Robertson, Scherzer approved the deal to Texas, where he'll join the American League West-leading Rangers, who at 60-45 are one game ahead of the Astros.

In return, the Mets will receive Luisangel Acuna, 21, a middle infielder and center fielder who will likely be among New York's top prospects.

The Houston Astros traded for veteran reliever Kendall Graveman on Friday, sending Triple-A catcher Korey Lee back to the Chicago White Sox in the deal.

Since Wednesday night, the White Sox have traded five pitchers -- Graveman, Lucas Giolito (Angels), Reynaldo Lopez (Angels), Lance Lynn (Dodgers) and Joe Kelly (Dodgers).
