Senior Matt Riebesell doubled in senior Chris Grillo with one out in the bottom of the 12th to give the Muhlenberg baseball team a 5-4 win against Franklin & Marshall and a sweep of a Centennial Conference doubleheader.

The Mules (12-11, 2-3), who won the first game 5-2, picked up their first CC wins of the season against the team that ended their 2018 campaign in the second round of the CC playoffs. And after giving up 57 runs in dropping their last four games, the Mules got four outstanding pitching performances in the sweep.

Junior Matthew D'Ambrosia worked eight solid innings, allowing seven hits and striking out five, to earn the win in the opener. Senior RJ Hennessey pitched a 1-2-3 ninth against the top of the the F&M lineup to land his second career save - his first in three years.

In the nightcap, sophomore Truman Devitt was brilliant in eight innings in just his second start of the season. He allowed only one earned run and struck out eight. Freshman Will Nomura pitched four hitless, scoreless innings in relief to earn his first career win.

The Diplomats (15-10, 2-3) turned a leadoff double into a quick run in the top of the first inning of the opener and led 1-0 heading into the bottom of the fifth. Senior Jon Capra led off the fifth with a single and came all the away around to score when the F&M pitcher threw away a sacrifice bunt by junior Brenden Weiss.

Sophomores Robert Cappadona and Cameron Miller added RBI singles before Riebesell capped the five-run upsrising with a two-run single.

F&M got one run back in the top of the sixth, but sophomore second baseman John Serruto prevented further damage by diving to his right to field a ground ball and get the third out with a runner on second base.

Serruto, who was 2-for-3 at the plate, also dove to his left to get an inning-ending out in the fourth.

Hennessey induced three ground ball outs in the top of the ninth to nail down the win.

The Diplomats again scored quickly at the start of the second game, but Muhlenberg took a 3-1 lead in the bottom of the second. Weiss started the rally with a sharp single off the leg of the F&M starting pitcher. Cappadona, who was 3-for-3 in the opener, brought in the first two runs with a single and scored the third on a wild pitch.

F&M plated three unearned run in the top of the third, and the score remained 4-3 until the bottom of the ninth, when senior Seth Wasserman led off with a single up the middle and was sacrificed to second by Cappadona. Serruto followed with a single up the middle, bringing home Wasserman with the tying run.

Nomura struck out the side after a leadoff walk in the 10th and retired all six batters he faced in the 11th and 12th. Wasserman came close to hitting a walkoff home run in the 11th, but his long drive to left was hauled in two steps from the fence.

Grillo beat out a slow roller up the middle with one out in the 12th and came all the way around on Riebesell's opposite-field double, sliding in safely just ahead of the tag.

In addition to his three hits in the nightcap, Riebesell also threw out two runners attempting to steal and picked another one off second. Serruto and Grillo also had three hits.

After playing only one game as long as 12 innings in their first 25 years in the CC, the Mules have played two this week. The extra-inning walkoff was the first for Muhlenberg at Cedarcreek Field since a memorable 10-9 win against Johns Hopkins in 11 innings in 2014. The Mules hadn't walked off in a game of 12 innings or more since 1976.
