The Chicago Cubs and New York Mets both made a flurry of moves leading up to the MLB trade deadline on Monday afternoon.

The 20-14 Cubs are in first place in the NL Central and wanted to fortify both their bullpen and position player depth. Chicago acquired lefty relievers Andrew Chafin (Arizona Diamondbacks) and Josh Osich (Boston Red Sox) to help out a rocky bullpen. The Cubs then acquired Cameron Maybin from the Detroit Tigers for outfield depth.

Chafin is currently injured and is hoping to return in a few weeks. If he's able to return soon enough, the Diamondbacks will get a low-level prospect, according to MLB Network's Jon Heyman. The lefty struggled to the tune of an 8.10 ERA before going on the shelf, but he was more effective in recent years.

The Cubs are getting Osich for a player to be named later. The 31-year-old has a 5.74 ERA in 13 appearances this season.

As for Maybin, Jason Beck of MLB.com says infield prospect Zack Short is going to Detroit. Maybin is hitting .244 this season with one home run and two RBI in 45 plate appearances.

Out in New York, the Mets acquired infielder Todd Frazier (Rangers), catcher Robinson Chirinos (Rangers) and pitcher Miguel Castro (Orioles), per Heyman. New York is 15-20 and five games back in the NL East, but the standings are bunched together behind the first-place Atlanta Braves.

Frazier returns to the Mets after his brief stay in Texas. He's hitting .241 with two dingers and seven RBI this season. The veteran played for the Mets in 2018 and 2019. The Rangers are getting a player to be named later for Frazier.

Chirinos has been awful at the plate this season. He had previously spent six years with the Rangers before going to the Astros last season, only to return to Texas for 2020. Unfortunately, he's hitting just .119 on the year. The Rangers are getting a player to be named later in the deal, per Mark Feinsand of MLB.com.

Castro has racked up 24 strikeouts in 15 2/3 innings this season while notching a 4.02 ERA out of the bullpen. The Mets are sending minor league left-hander Kevin Smith to Baltimore for Castro.
