"Jacobsen was the guy I wanted in that situation," Suns manager Matt LeCroy said. "He has been hot. He comes to the park every day ready to play and he has been playing a lot right now. I didn't think we played really well today. If we wouldn't have won at least one of those games, it would have been tough for me to swallow."
Jose Lozada drew a leadoff walk off Andrew Loomis as conditions worsened. Steve Lombardozzi moved the runner with a bunt and Derek Norris was intentionally walked before Aaron Seuss popped out to left.
Jacobsen worked the count full before uncoiling a liner that fell just inside the line to drive home the winning run.
"They came out and (worked) on the mound and the plate. It was like a stalling tactic," Jacobsen said. "There was nothing I could do about that. What I could do was watch the pitcher and get the timing. I was 0-for-3 in the game. I wanted to help the team."
The Suns held a 2-1 lead in the seventh when Greensboro used an infield single by Emilio Ontiveros, a wild pitch and Justin Bass' single to send the game into extra innings. A wild pitch also changed the complexion of the first game.
The Suns threw out two runners at the plate in the eighth to give Jacobsen his chance. Chris Lugo won the game in relief of starter Patrick Arnold. Seuss homered in the fourth and Lozada had an RBI single in the fifth.
In the opener, Suns starter Jack McGeary (0-2) issued a one-out walk in the second to Brandon Turner and Joel Staples singled before a wild pitch advanced the runners and erased any double-play possibility. Torre Langley's grounder, a Jason Bass single and Isaac Galloway's double produced a 3-1 lead.
The Suns got their only run in the third when Stephen Englund led off with a double off starter Johnny Dorn, moved to second on Chris Curran's sacrifice bunt and scored on Nick Arata's grounder.
