Duke played three rollercoaster-type games at Georgia Tech this weekend and lost two of them.

Runs weren’t hard to come by and there was little separation, with a combined score of 29-28 in Georgia Tech’s favor. The Yellow Jackets won 11-8 and 8-6 on Friday and Sunday, respectively; Duke won the middle game of the series 14-10 on Saturday.

The Blue Devils entered the weekend looking to solidify their credentials for being a regional host in the NCAA tournament. That possibility remains, and next weekend’s home series against UNC, which has the best record in the ACC, looms large with résumé-strengthening chances.

Of greater concern than losing two of three this weekend is the health of two of Duke’s most-important players. Starting pitcher Jonathan Santucci was scratched from his start on Friday; third baseman Ben Miller was removed from Sunday’s lineup.

Here is a recap of each game this weekend:

On Sunday, Duke ran the gamut of emotions in the seventh inning.

The Blue Devils (34-16, 15-12 ACC) got a game-tying three-run home run by Zac Morris with two outs. After AJ Gracia doubled and Georgia Tech (30-19, 14-13) made a pitching change, Alex Stone — who was a combined 8-for-15 with 10 RBI in the series — hit a home run to put Duke up 6-4.

Obviously, the lead didn’t last.

Jackson Emus (0-1) allowed a leadoff single in the seventh and walked the next two batters; he was relieved by Jimmy Romano. GT got a sacrifice fly to make it a one-run game, and took the lead on a two-run single by Cam Jones. The Yellow Jackets tacked on another run with Carson Kerce’s single.

Duke put two runners on in the eighth and couldn’t score; it got a two-out single in the ninth before the end of the game.

Duke’s only lead of the game was in the seventh; its only run to that point came in on a triple by Harrison Rogers, who replaced Miller in the lineup.

The Blue Devils used eight pitchers. Andrew Healy started and gave up one run in two innings. David Boisvert and Fran Oschell III followed with one scoreless inning each. Gabriel Nard gave up a run and Tim Noone was charged with allowing two in the middle innings.

On Saturday, Logan Bravo doubled in a run to break a 10-10 tie in the eighth inning and Devin Obee added a sacrifice fly to make it a two-run lead.

AJ Gracia supplied more insurance in the ninth with a two-run homer, his 12th of the season and a program record for a freshman.

That capped a huge day for Gracia and the middle of Duke’s lineup, in general. Gracia, Alex Stone and Bravo, hitting 3-4-5, respectively, were a combined 9-for-16 with nine RBI and nine runs scored. Stone hit a three-run homer in the fifth that tied the game at 7-7, and Bravo made it back-to-back homers to give the Blue Devils a lead. Bravo also homered in the sixth to put Duke ahead 10-8.

Georgia Tech tied the game in the bottom of the sixth with John Giesler’s two-run single. That was it for the Yellow Jackets’ offense, though, with Gabriel Nard (2-2) working around two singles to start the seventh, and Charlie Beilenson retiring all six batters he faced across the eighth and ninth innings for his 11th save; he struck out the last five batters.

Eight of Duke’s nine starters in its lineup had at least one hit. Wallace Clark’s three-run double in the fourth started the Blue Devils’ comeback, and Chase Krewson was 2-for-5.

Kyle Johnson started and was tagged with six runs on eight hits in his two innings. Tim Noone gave up one run in working two innings, and James Tallon was charged with allowing GT’s other three runs.

On Friday, the makeshift pitching effort in the wake of Santucci’s scratch gave up at least one run in six of the eight innings Georgia Tech came to bat.

Ryan Higgins started the game and gave up two runs in the first inning, leaving in the second after recording five outs. Jimmy Romano relieved him and was charged with allowing four runs on three hits and a walk, only notching two outs.

Gabriel Nard was the only one of Duke’s six pitchers who escaped without allowing a run; he faced four batters and notched two outs.

David Boisvert (2-1) took the loss for allowing two runs, one each in the fourth and fifth. Fran Oschell III gave up a run in the sixth and walked the leadoff batter of the eighth; he was replaced by Charlie Beilenson, who allowed Oschell’s runner to score and gave up a run of his own to complete the damage.

Duke had a four-run lead before GT came to the plate; the Blue Devils got a three-run homer by Alex Stone in the first, and added an unearned run on a single by Wallace Clark. Zac Morris had an RBI single in the third and Logan Bravo had a two-run homer in the fourth that gave Duke a 7-6 lead.

Duke’s only other run came in the eighth on a single by Stone, who was 3-for-4, and made it a 9-8 deficit before GT’s pair of insurance runs. The Blue Devils didn’t have a baserunner in the ninth.
