How deep is the Cubs’ 40-man roster now that the trade deadline has passed?

The Aug. 31 trade deadline, which allowed teams to make deals on players on waivers, no longer exists. So teams now must rely on internal depth as the season unfolds.

The trade Wednesday of Martin Maldonado to the Astros leaves the Cubs with only two catchers on the 25-man roster — Willson Contreras and Victor Caratini — and they would need to make room to add a player to their 40-man roster.

Here’s a look at the team’s current roster depth.

Catcher

Triple-A Iowa catcher Taylor Davis has spent parts of three seasons with the Cubs and has caught Yu Darvish.

“We feel good about Taylor,” general manager Jed Hoyer said. “Taylor has been solid for us and has done a good job up there. We feel good about him.”

First base

The Cubs have plenty of coverage at first on the major-league roster. Contreras and Caratini and infielders David Bote and Javier Baez all can spell Anthony Rizzo if needed.

Second base

The Cubs have plenty of candidates on the major-league roster, so they wouldn’t need to promote a player from Iowa. Daniel Descalso is on the 10-day injured list, and infielder Ben Zobrist is expected to start a minor-league assignment this weekend. Zobrist is on the restricted list and hasn’t played since May 6.

Third base

Bote and Baez can spell Kris Bryant at third.

Shortstop

Addison Russell, who was optioned to Iowa on July 24, has played shortstop throughout his career. Before his demotion, he mostly played second for the Cubs.

Outfield

Mark Zagunis spent nearly two months with the Cubs before being optioned to Iowa. The Cubs are stocked with outfielders. Trent Giambrone, a 5-foot-8 infielder, has been playing the outfield more frequently this season at Iowa and has 20 home runs. But he is not on the 40-man roster.

Starting pitchers

Iowa’s rotation includes Alec Mills, who has started two games for the Cubs and has pitched in 12 major-league games over three seasons. Adbert Alzolay pitched in three games for the Cubs this season but is on the seven-day injured list with Iowa.

Right-handed relievers

Dillon Maples has shown flashes of promise over three seasons with the Cubs but is in Iowa with Duane Underwood Jr., who has made a smooth transition from a starting role, and James Norwood. All three are on the 40-man roster.

There are no indications that former closer Brandon Morrow or Allen Webster will return from the IL, which prompted the Cubs to acquire David Phelps from the Blue Jays on Tuesday.

Left-handed relievers

Brad Wieck, acquired from the Padres for Carl Edwards Jr., can provide depth but was assigned to Iowa.

Iowa’s Randy Rosario has spent parts of the last two season with the Cubs. It appears murky as to whether Xavier Cedeno, who was transferred to the 60-day IL because of left wrist inflammation, will return.

If Danny Hultzen is promoted, it would complete a fascinating comeback. Hultzen, the second pick in the 2011 draft by the Mariners, missed the entire 2014 and 2017 seasons because of injuries but has a 2.25 ERA in eight appearances while striking out 12 in eight innings.

Hultzen, however, is not on the 40-man roster.
