The MLB trade deadline concluded at 4:00 p.m. on Monday. Many pieces were Moved on the last day to trade players, with Yu Darvish, Sonny Gray, and Tony Watson leading the way. However, there were plenty of players that were not moved on this day. These are the biggest question marks from teams that needed to make a move.

Lance Lynn, St. Louis Cardinals

Lynn is set to be a Free Agent at the end of the season. The Royals could have benefited from having Lynn slide into their rotation, and were reported to be willing to part with prospects. The Cardinals never declared that they were selling.

The team is 4.5 games out of the division lead, and must believe that they can still make a run to overtake the Chicago Cubs.

Zach Britton, Baltimore Orioles

Britton is a year removed from finishing fourth in Cy Young voting, but his value was high while in the midst of an injury-plagued season. The Orioles are 50-54, and are close to being out of playoff contention. Even at their low odds, the Baltimore brass belive they can make a run at the wild card as they are 4.5 games out. Britton’s asking price might have been too high, but he is set to be a free agent in 2018. The team missed out on retooling their roster.

The Miami Marlins' entire trade block

Let’s recap. The Marlins have been selling for nearly a month, and they only moved closer AJ Ramos?

The team had All-Stars Marcell Ozuna, and Giancarlo Stanton. Christian Yelich could have brought in a decent haul. Not to mention Dan Straily is having a solid season and has a cost-controlled contract. Yet, all of these names will be with the Marlins. Maybe the sell of the team will give the team a busy winter.

Ervin Santana, Minnesota Twins

The Twins went from first place in the Central to being seven games out. The team is likely to miss the playoffs. The good news is that none of this was expected this year, but the team could have received a package of prospects for their All-Star starting pitcher. Santana is having a career year and is a free agent at the end of the season.

The Twins struck out on a potential step for next season. The Astros missed out too, as they didn't even make a move.

Jay Bruce, New York Mets

Bruce has over 20 home runs on the season and is going to be a free agent at the end of the year. The Mets are not going to make the playoffs this season, so the team would have only gained from dealing Bruce. The Mets have had an injury-plagued year in terms of their rotation. Bruce is not a building block, so it’s puzzling why Bruce was never moved.
