MILWAUKEE, May 26 (UPI) -- Pedro Alvarez
delivered a key two-run double and Pittsburgh's bullpen strung together four shutout innings Sunday, boosting the Pirates over Milwaukee 5-4.
Leading 2-0 in the third, the Pirates double the advantage when Alvarez smoked a 1-0 pitch into the right-field corner, chasing home Andrew McCutchen and Gaby Sanchez.
Starling Marte added a sacrifice fly in the sixth for the Bucs, who took the rubber match of their three-game series and grabbed a share of the National League Central lead with their 16th victory in May.
Starter Wandy Rodriguez (6-2) lasted just long enough to earn the win, yielding three runs on seven hits.
Vin Mazzaro and Mark Melancon combined for three scoreless relief frames and Jason Grilli racked up his MLB-best 20th save for the Pirates.
Milwaukee's Yovani Gallardo (3-5) was touched for four runs on five hits over four full frames.
Ryan Braun supplied a bases-clearing double for the Brewers.
