READING, Pa. — Mickey Pena (2-0) fired five scoreless innings, and Portland (19-10) used a three-run third inning to beat the Reading Fightin Phils (14-14) 4-0 on Tuesday night at FirstEnergy Stadium. Portland has won four straight and moves nine games over .500 for the first time this season.

Pena allowed one runner past second base, yielding three hits (two infield singles) and two walks while fanning five. The Mission, Texas native earned his second win of the season, and has back-to-back, five-inning shutout performances against Reading.

Reading starter Severino Gonzalez (3-2) beat the Sea Dogs in his last start on April 30 at Hadlock Field, but took the loss on Tuesday. Gonzalez gave up four runs on six hits over six innings.

The Sea Dogs got to Gonzalez in the third inning, sending eight men to the plate and continuing their two-out magic. Shannon Wilkerson led off the frame with a single and Deven Marrero drew a one-out walk. Travis Shaw knocked in the game’s first run with a single off the shortstop’s glove for his 22nd RBI. With two outs, Blake Swihart and Henry Ramos delivered back-to-back RBI singles. Portland has scored 50 percent of its runs this season with two outs.

In the fourth, Betts picked up a hit for the 26th time in 28 games, blooping an RBI single to score Derrik Gibson and give Portland a 4-0 advantage. Betts extended his on-base streak to 58 straight games, dating back to last Aug. 2 (63 including the playoffs).

Nate Reed, who grew up in Temple, Pa., just two miles from FirstEnergy Stadium, fired three scoreless to earn his first Double-A hold. Aaron Kurcz closed out the win, working around leadoff singles in the ninth. The Sea Dogs notched their third shutout of the season, allowing just six hits and holding Reading to 0-for-5 with runners in scoring position.

Portland has won four of their last five against Reading, and holds a 1.5-game lead over Trenton for the top spot in the Eastern Division.
