PORTLAND, Ore. --- Portland's Chris Clements tossed a complete-game shutout and the Pilots finished off the sweep of Northern Colorado with a 4-0 win over the Bears on Sunday afternoon at a sun-splashed Joe Etzel Field. Clements struck out 13 to claim his second consecutive complete-game win.
 
Portland extends its winning streak to six straight games, which is the longest stretch without a loss since 2012. The Pilots' 13-4 record is the best start to a season since that same year, when Portland also won 13 of their first 17 games.
 
Clements scattered just six hits to improve to 4-0 on the year. He walked only one, struck out the side in the top of the third inning, and allowed only two UNC (2-11) runners to reach third base. The 13 K's are the most for a Portland pitcher since Kevin Baker also fanned 13 in 2017.
 
All four Portland runs came in the bottom of the fourth inning. After the frame began with a strike out, Daniel Lopez and Cody Hawken both reached base with a walk and a hit-by-pitch, respectively. Hunter Montgomery then came through with an RBI single to left field, which scored Lopez with the game's first run.
 
Another hit-by-pitch loaded the bases, and Tracye Tammaro brought all three runners home with a two-out double into the right-center gap. The 4-0 lead was more than enough for Clements, a senior righty who also went the distance during a win over Stephen F. Austin last weekend to earn WCC Pitcher of the Week honors.
 
Northern Colorado used five pitchers on the afternoon with the loss going to reliever Carter Chacon (1-1). He went 1.1 innings and was charged with two runs, and reliever Bill Moreland allowed the other two runs in the fourth.
 
Portland defeated the Bears on Friday night and took both ends of a double header on Saturday en route to the four-game sweep. It's the first four-game series sweep for the Pilots since taking four from Eastern Oregon in 1982, and it's the first against a DI opponent since winning four against Seattle in 1980.
 
Next up for the Pilots is a visit from Seattle U on Wednesday. First pitch at Joe Etzel Field is set for 3 p.m.
