Craig Kimbrel, the four-time All-Star acquired by the San Diego Padres in April, could change teams this week for the second time in the last four months.

Rival executives said the Padres are "pushing" their players ahead of the July 31 non-waiver trade deadline, while both the Toronto Blue Jays and Washington Nationals have reportedly showed some interest in the 27-year-old, according to Jon Heyman of CBS Sports.

Though Kimbrel remains one of the game's elite closers - he owns a career 1.59 ERA and leads the majors with 214 saves since 2011 - both the Blue Jays and Nationals have also been linked to Philadelphia Phillies closer Jonathan Papelbon and the trade market remains saturated with experienced ninth-inning options.

The Houston Astros, meanwhile, are also thought to have some interest in Kimbrel, though the $25 million remaining on his contract over the next two seasons has given them pause.

Despite a slow start to his tenure in San Diego, Kimbrel owns a 2.75 ERA with a 1.12 WHIP over 41 appearances this season, notching 55 strikeouts while converting 29 saves in 30 chances in 2015.
