MLB Players To Grab Before the Offseason for Dynasty/Keeper: Middle Infield

As we hit the final weeks of the fantasy baseball season and many turn their minds to fantasy football, there is an opportunity for you to take advantage. It is easy to see and jump on players who break out early in the season, but many miss those who perform well late.

This week, I will walk position by position and look at some players who may have more value than you think and could not only help your team down the stretch but in 2027 as well.

Today, we look at three MLB middle infielders who look the part and have provided value, but are still underrostered. Looking for a middle infielder for 2027 or to help down the stretch? This article should help you out.

MLB Middle Infielders to Grab Before the 2026 Season Ends

Justin Foscue, 2B, Texas Rangers

Foscue was once a top 100 prospect as he put up four straight impressive seasons between 2021 and 2024. As a 2020 first-round pick, Foscue never really put it together and looked like a quad-A type player due to some major struggles in the majors. After making his MLB debut in 2024, Foscue got just nine plate appearances in 2025. With adequate playing time this year, Foscue has put up respectable numbers, hitting 11 home runs with a .271/.330/.508 slash.

Since mid-August, when Foscue began to play more regularly, he has four home runs and five doubles in 55 plate appearances. He has a slash of .333/.382/.667 with an 18.2 percent strikeout rate.

On the season, Foscue has an average exit velocity of 89.5 mph and a 90th percentile of 104 mph, but he creates strong barrels thanks to ideal launch angles. The low swing rate is an issue, but the chase rate is respectable.

Foscue is also making a ton of contact, having an 87 percent in-zone contact rate with an overall mark above 80 percent. He pulls the ball in the air well.

The thing to note is that Foscue is on the weak side of a platoon in Texas. But I do think there is use here in daily leagues and deeper formats. He has shown enough to earn more playing time in 2027.

Javier Sanoja, INF/OF, Miami Marlins

At the time of writing this, Sanoja is on a nine-game hitting streak and has hits in 19 of his last 22 games. While not flashy, Sanoja has been very solid this year and has positional eligibility at nearly every position in the field. In 421 plate appearances this year, Sanoja has a .291/.331/.441 slash with eight home runs and nine stolen bases.

While more of a niche play, Sanoja does have value in points leagues. The profile is kind of Luis Arraez lite. The hit tool is elite with a 93 percent in-zone contact rate and an 89 percent overall mark. He chases a lot and does not hit the ball overly hard, but Sanoja has value.

Since the start of the second half, Sanoja is slashing .317/.356/.491 with five home runs and 12 doubles. The exit velocities have slightly improved, and the production is there.

He is rostered in just 50 percent of Fantrax leagues, and in a batting average league, there is value if you have enough power elsewhere in the lineup.

Adael Amador, 2B, Colorado Rockies

Sometimes it takes longer for a prospect to click, and it is important to remember that Amador is just 23 years old. Amador looked the part in Triple-A, hitting 11 home runs with 11 stolen bases while slashing .269/.368/.431. The data was respectable, with impressive contact skills, a low chase rate, and improving exit velocities.

Amador has been back in the Majors for just 37 plate appearances, so this is a complete dart throw on him, but he has three home runs and a .344/.417/.688 slash. The BABIP is driving the profile at .348; he is creating barrels, and the exit velocity data is in line with what we saw in Triple-A.

The zone contact rate and chase rate are also good, but again we are looking at a tiny sample. His Triple-A max exit velocity of 109 mph this year has nearly been matched at 108.5 mph in the Majors.

How Amador fares is still a question mark, but he is rostered in just 23 percent of Fantrax leagues and is worth a shot in deeper formats.
