Needing to fortify their pitching staff for the stretch run, the Minnesota Twins reportedly struck a deal with the Miami Marlins for Sergio Romo on Saturday.

Per Joel Sherman of the New York Post, the Twins are getting Romo and a minor league pitcher from the Marlins.

Per Betsy Helfand of the St. Paul Pioneer-Press, Miami will receive minor league first baseman Lewin Diaz.

Per MLB.com's Mark Feinsand, right-handed pitcher Chris Vallimont is the other piece going back to Minnesota. The 22-year-old is currently in High-A and has a 3.16 ERA with 122 strikeouts in 105.1 innings this season.

Diaz is 22 years old and was promoted to Double-A on June 19. MLB.com ranked him as the No. 30 prospect in the Twins' system. The Dominican Republic native has a .297/.339/.558 slash line with 19 homers and 61 RBI in 89 games.

The Twins are locked in a battle with the Cleveland Indians in the American League Central. Their bullpen has been a source of frustration, making it likely the team would focus on upgrading that area prior to the July 31 trade deadline.

Minnesota's relief corps entered Saturday ranked 14th in MLB with a 4.41 ERA and 22nd in opponent batting average (.260).

Romo isn't an overpowering pitcher who will shut down an opposing lineup, but the former All-Star remains an effective arm who excels at getting out right-handed hitters. The 36-year-old has a 3.58 ERA with 33 strikeouts in 37.2 innings.
