The Texas Rangers have signed starting pitcher Johnny Cueto to a minor-league contract on Tuesday. The 38-year-old lands a deal with the defending World Series champions after a rough year with the Miami Marlins. Cueto posted a 6.02 ERA, 1.26 WHIP, and a 39/15 K/BB ratio over 52 1/3 innings with the Marlins last season. It's uncertain what Cueto still has left in the tank, but he'll at least be additional depth for the organization. Cueto has plenty of experience but is unlikely to offer any kind of fantasy value.

Washington Nationals catcher Keibert Ruiz (illness) is scheduled to begin a minor-league rehab assignment with Double-A Harrisburg on Tuesday. Ruiz landed on the injured list last week with influenza. Barring any setbacks, Ruiz should be ready to return to the Nats lineup at some point later this week. Until then, Riley Adams and Drew Millas figure to split up the playing time behind the plate.

Philadelphia Phillies starting pitcher Taijuan Walker (shoulder) is set to make his season debut against the San Diego Padres on Sunday. The 31-year-old appears to be ready to pitch after missing time due to right shoulder soreness. Walker isn't an excellent fantasy option, but he could be worth a look in deeper mixed leagues. He has shown in the past that he has the skills to be a viable option in the big leagues. Fantasy managers who are in need of pitching help should keep an eye on Walker.

New York Yankees infielder DJ LeMahieu (foot) is scheduled to begin a minor-league rehab assignment with Double-A Somerset on Tuesday. It sounds like the plan is for LeMahieu to play four games in the minors before possibly returning to the Yankees roster. The veteran slugger has been sidelined all season due to a fractured foot. The Yankees could certainly use LeMahieu's help given their current struggles at the plate. Fantasy managers should wait patiently as it sounds like LeMahieu should be back soon.

Baltimore Orioles first baseman Ryan Mountcastle (knee) remains out of the starting lineup ahead of Tuesday's game against the Los Angeles Angels. The right-handed slugger will miss his second game in a row due to knee soreness. That means, Ryan O'Hearn will cover first base and bat third on Tuesday. It doesn't sound like this issue will force Mountcastle to miss significant time. For now, fantasy managers should consider him as day-to-day.
