The Terrapins baseball team entered this weekend with a 3-9 record in ACC road games. But on Sunday the Terps completed their third conference sweep of the season at Pittsburgh.

The Terps scored four runs in the last two innings and overcame a seventh-inning 4-2 deficit to beat Pittsburgh 6-4 at Charles L. Cost Field on Sunday in their ACC regular-season finale. The Terps, who trailed in all three games this weekend, have won 15 league games this season to tie a school record.

Left-hander Jake Drossner pitched 5.1 scoreless innings Sunday and allowed two hits and three walks while striking out two. The sophomore retired 11 straight at one point.

In the fourth inning, left fielder Tim Lewis hit a lead off double and after advancing to third on a sacrifice fly, scored on a grounder. Two doubles, from catcher Kevin Martir and then center fielder Charlie White, produced the second run of the inning.

Big innings helped the Terps notch victories on Friday and Saturday, but the Terps (33-19, 15-14) didn’t produce a big inning Sunday. Instead, the Panthers (22-27, 11-16), who entered Sunday with two runs in the series, scored four runs in the seventh and temporarily took the lead.

The Panthers’ four runs in the seventh ended the Terps’ bullpen’s streak of 21.2 scoreless innings. Right-hander Bobby Ruse, who replaced Drossner, allowed the first three batters to reach and surrendered a run in the process. Right-hander Kevin Mooney, the Terps closer, issued a bases-loaded walk and gave up a two-RBI single before he got the final three outs of the inning.

 The Terps tied the game at 4 with two runs in the eighth. They loaded the bases with one out and wwo straight grounders plated runs. First, there was miscommunication between the Panthers middle infielders as designated hitter Nick Cieri hit a chopper to short. Catcher Kevin Martir then hit a slow roller to third, and shortstop Blake Schmit scampered home.

Mooney worked his way out of trouble in the eighth after he allowed two Panthers to reach with two outs. A ground out to Schmit ended the threat.

The Terps scored the go-ahead run in the ninth. First baseman LaMonte Wade led off the ninth with a triple, and second baseman Brandon Lowe, who entered Sunday second in the ACC in batting average, drove him in with a single to left.

Mooney pitched a 1-2-3 ninth to pick up his first win of the season.
