John McDonald went 2-for-4 and hit a three-run homer in the Diamondbacks' 8-5 defeat of the Brewers on Saturday night. McDonald showed nothing at all offensively after arriving in Arizona in last year's Aaron Hill-Kelly Johnson trade, but he's hitting .317 with two homers in 60 at-bats this season. He's been a big help with Stephen Drew sidelined.

Diamondbacks signed INF John McDonald to a two-year, $3 million contract. McDonald gets $1.5 million in 2012 and another $1.5 million in 2013. The 37-year-old batted just .169/.222/.203 in 63 plate appearances after joining the D'Backs in late August, but he's a pretty slick defensive infielder and should be a reliable utilityman in 2012. If Stephen Drew (ankle) isn't back to 100 percent by Opening Day, the veteran McDonald could even draw some starts in the early going at shortstop.

Diamondbacks acquired SS John McDonald and 2B Aaron Hill from the Blue Jays for 2B Kelly Johnson. McDonald was mostly a throw-in, but he'll provide needed depth at shortstop for the Diamondbacks, who will be without Stephen Drew (fractured ankle) down the stretch. McDonald, 36, has a weak .606 career OPS. He'll become a free agent this winter.

Blue Jays activated INF John McDonald from the 15-day disabled list. McDonald missed around two weeks with a hamstring strain. He has a .190/.252/.295 slash line this year and will return to his role as a utility infielder.
