Major League Baseball's trade deadline isn't until 6 p.m. ET on Tuesday, but there already have been some big deals made.
In Monday's first big stunner, the San Diego Padres picked up four-time All-Star Josh Hader from the Milwaukee Brewers in exchange for four players, including left-handed reliever Taylor Rogers.
And the New York Yankees added to their pre-trade deadline acquisition of All-Star outfielder Andrew Benintendi by adding a top setup man from the Chicago Cubs to their bullpen.
What other deals could be made as the countdown to the deadline continues? USA TODAY Sports will provide updates on all the key trades.
