A whopping 18 baseball trades were completed on Monday, more than half of which happened within the final hour leading up to the 4 p.m. ET deadline. With that night’s slate beginning only hours later -- not to mention the fact that 14 teams were off Monday -- Tuesday will feature the debuts of many players on their new teams.

More importantly, on Tuesday we'll see the first hints of those players’ roles for their new teams. We saw a few of them Monday night, including Texas Rangers general manager Jon Daniels' statement that Sam Dyson would remain the team’s closer despite the acquisition of Jeremy Jeffress, and that Carlos Beltran would bat behind Adrian Beltre. We also learned of the New York Mets' plans to play Yoenis Cespedes (left field) and Jay Bruce (right field) at the outfield corners, with Curtis Granderson and Michael Conforto sharing center field. But many plans have yet to be made.

Perhaps the most attention will be paid to the Rangers’ lineup release, after the team acquired catcher Jonathan Lucroy and Beltran. Though Lucroy seems likely to slot in sixth or seventh, he was a No. 2 hitter on 82 occasions for the 2015 Milwaukee Brewers, and his .359 on-base percentage in 2016 exceeds that of any qualified Rangers hitter, and therefore he could sneak into a higher spot.

Such a decision might signal a future reduction in playing time for Jurickson Profar, even after the demotion of Joey Gallo to Triple-A Round Rock on Monday night. Profar loses the DH spot as a safety net now that Beltran is in town, and he’ll also be blocked in the corner outfield once Shin-Soo Choo returns to action (expected to be Thursday). Profar, whose fantasy stock was on the rise when Prince Fielder was ruled out for the year, is now in danger of returning to his part-time utilityman role; or worse, the right-handed part of a platoon (a role for which he’s poorly suited). That’s why these next two days could provide a hint: If Profar leads off in both games playing positions besides left field or DH, it could signal the Rangers’ desire to find creative places to play him even after Choo’s eventual return.

Still, even that might not be enough, as Choo has batted first or second in 32 games that he has started this season, and could easily slide back into the leadoff role on Thursday. Lucroy’s spot on Tuesday, however, could be telling, and there’s little doubt that the No. 2 hole would be more beneficial for his daily-league value than No. 6 or 7. That said, such a move would hurt current No. 2 hitter Nomar Mazara's value, as he’d be the one moved down in that event.

Bruce’s position for the Mets might be known, but his lineup spot isn’t yet. Against right-handed pitchers, he’ll almost assuredly bat fourth, directly behind Cespedes, but injuries and the team’s center field partnership should create opportunities for Nos. 1 and 2 hitters in the coming days. Neil Walker will probably bat second most days, but when Granderson sits for Conforto, who leads off? The Mets have already given at least 10 starts in the Nos. 1-2 lineup spots to five different players -- Granderson (88), Asdrubal Cabrera (43), David Wright (28), Jose Reyes (16) and Juan Lagares (10) -- with the latter three currently on the DL and Cabrera perhaps headed there.

Could James Loney, Justin Ruggiano or Kelly Johnson sneak in the occasional start at leadoff or No. 2 in the order? It’s possible, and depending upon the specific pitcher matchup or ballpark (road games), that could be a daily opportunity. Certainly, owners of Bruce, the National League’s leader in RBIs (80), want to see as many high on-base percentages as possible slotted ahead of him.

The Los Angeles Dodgers, who acquired Josh Reddick and Rich Hill on Monday, might be more focused on Yasiel Puig's status than either of their new acquisitions Tuesday. After several contradictory reports regarding Puig on Monday night, the outfielder appears ticketed for Triple-A Oklahoma City, freeing up right field as well as a probable No. 5 or 6 spot in the Dodgers’ lineup for Reddick. It’s curious timing considering Puig’s .308/.390/.440 numbers in 28 games since returning from the DL, but the decision at least solidifies Reddick’s role for his new team.

The Tampa Bay Rays, who traded both Brandon Guyer and Steve Pearce on Monday, provided us a glimpse of their new lineup against left-handed pitchers that evening, with Logan Forsythe leading off, Desmond Jennings in left field and both Gordon Beckham and Nick Franklin in the lineup. The result: An eight-inning, 16-strikeout masterpiece by opposing lefty Danny Duffy. That’s not a stat line one should expect from every opposing left-hander, but Guyer (.473) and Pearce (.510) were not only the team’s top two hitters in terms of wOBA against lefties this season -- they were two of the team’s five players with a wOBA greater than .330 against that side. Even with the addition of new shortstop Matt Duffy -- he actually has a greater wOBA against righties (.322) than lefties (.320) in his career -- this will be a lineup to exploit from either side, especially at Tropicana Field.

Speaking of the Rays, Matt Andriese will replace the traded Matt Moore in the rotation beginning on Tuesday night. Andriese isn’t a fantasy consideration on Tuesday, having thrown 32 pitches in relief as recently as Saturday, meaning he’ll need to be stretched out over one or two more turns, but he has a 3.19 ERA, 1.23 WHIP and a promising 6.6 percent walk rate in 16 career big league starts, and should be added in deeper-than-standard leagues.

The New York Yankees, who in the past nine days traded Aroldis Chapman, Andrew Miller, Beltran and Ivan Nova, had new closer Dellin Betances notch his first save on Monday, though the team’s long-term plans to replace Beltran and Nova remain unclear. Rob Refsnyder started in right field, batting eighth, in Beltran’s place on Monday, though Aaron Hicks and perhaps eventually Aaron Judge could be factors in that spot in the coming days. In addition, with the Yankees now firmly turning the page to 2017, releasing Alex Rodriguez might be a consideration; Gary Sanchez is reportedly due for a promotion soon, and he might grab regular playing time between catcher and DH (Brian McCann shifting to DH on Sanchez’s catching days). In leagues that use two catchers, Sanchez is worth an add right now.

Other quick notes: The Cincinnati Reds have a right field spot to fill, and it’s possible that Adam Duvall could merely shift there to free up a regular left-field role for Jose Peraza, which was the team’s arrangement on Sunday. Peraza is well worth the speculative add as a second base-eligible player who can contribute a healthy number of stolen bases. ... The Oakland Athletics are expected to give Max Muncy, Jake Smolinski and Danny Valencia additional at-bats in right field following the Reddick trade.
