MLB Week-in-Review: Blake Swihart promoted, Yankees won't pay A-Rod

April is officially over and May baseball is here. The Yankees will not pay A-Rod his bonus home run money and the Brewers may be ready for a fire sale.

Diamondbacks place Archie Bradley on 15-day DL

Bradley was hit in the face by a Carlos Gonzalez line drive early in the week. Double-A reliever Enrique Burgos took his spot on the roster, however Arizona will be without an arm that was having success. Bradley allowed four runs over 20 innings to open the year. He did have minor control problems, though, walking 11.

Nationals sign Jose Valverde

The 37-year old was signed to a minor league deal and adds experience to the back of Washington's bullpen. He was an All-Star in 2007, 2010, and 2011, and opted out of his deal with the Padres last spring after not making San Diego's 25-man roster.

With Rafael Martin and Craig Stammen on the disabled list, Valverde adds another right-handed arm to the bullpen mix.

Minnesota open to rebuilding?

Minnesota has lost Casey Fien, Jordan Schafer, and Phil Hughes to injuries and may now be committed to finding young talent. It has been a rough stretch for the Twins, and Daily Dish's Mike Bates believes we will learn just how serious the club is about winning based on their moves over the next few weeks.

Mets not open to trading Bartolo Colon

Colon was thought to be a veteran option who New York could move once its entire rotation was healthy and consistent, but after Colon's 4-1 start, the organization's thoughts have changed. The Mets have several young starting options, but if Colon continues to have success, he could remain with New York.

Braves promote Mike Foltynewicz

Foltynewicz was acquired in the Evan Gattis deal. He boasts a power fastball but has been plagued by control problems in the past. Regardless, Atlanta's roster could prove to be notably better with him on it.

The draft and imminent trades

Drafted players can now be traded after the World Series. Daily Dish's Jordan Freemyer is fond of the change:

The rule change closes a loophole that was beneficial to no one, as it complicated negotiations for teams in making trades and left recent draft picks in limbo if they were involved in a trade during their first year as a professional. With the new deadline in effect, things should be much easier for teams and players going forward.

Reds' Homer Bailey out with Tommy John surgery

Bailey made two starts and allowed seven runs in 11.1 innings but had success with Cincinnati in 2014. He signed a six-year, $105 million contract before the start of last season but will now be out until 2016.

Boston promotes Blake Swihart

The organization is reportedly concerned with the status of Ryan Hanigan (fractured finger) and even after promoting Swihart may be in pursuit of starting depth.

Milwaukee open to selling key pieces

The Brewers may deal Kyle Lohse, Aramis Ramirez, and Matt Garza after a slow start to the 2015 campaign.

Phillies 'waiting for trade partner' for Jonathan Papelbon, Cole Hamels

Chase Utley could also be dealt in the coming weeks.

Giants seeking upgrade at third base

Casey McGehee is off to a slow start and the Mets' Daniel Murphy could be expendable.

Yankees will not pay Alex Rodriguez

Home run bonus money is not happening.
